"Put it on the train; see if it gets off at Westport" is an old saying on Madison Ave. told to me by an editor at the Princeton University Press. My Father did just that for decades, get off the train there that is.
Westport in the 70s didn't have its commercial flare. Now mansions are cultivated where apple orchards and strawberry fields once were. The downtown where George Washington dismounted was home to a certain cigar smoking American woman of German ancestry by the name of Sigrid Schultz.
Today a plaque rests at the approximate spot where Washington relaxed in a little tavern. Behind the Episcopal church where this tavern once stood was a ramshackle home covered over with weeds and shrubbery. Bowing limbs shielded from view the little white house exempt from the Westport tax roles. Before I was born Sigrid had cut a deal with the town that upon her death they could make the property a parking lot but that until that day she would pay no property taxes. They hadn't counted on her living for so long. After all, the crippling effect of Nazi bullets had begun to take its toll upon her once ravenous beauty. Just as she had outsmarted Hitler, so too this suitably located hamlet.
Sigrid had written a book in the 30s which she was very proud of. She was proud of being the first women Chief of Central Europe for the Chicago Tribune. There was a network in the Berlin of the 30s that included my biological Grandfather. Officially employed by the U.S. Treasury Dept., my Grandfather was part of that clique of Americans milling about Berlin during the buildup. He made haste for Paris and eventually shipped back to the States. Sigrid stayed on to report the battles under another name and date.
Now, the full circle of coincidence. My mother, being an investigative reporter and political editor for the Hartford Courant, would run errands for Sigrid as the arthritis had confined her to bed. More often than not I was schlepped along for the ride. My mother had her hands full with armored car heists, suspicious murders, provocative human-interest stories (for which she was nominated for a Pulitzer) and dinners with Ella, another cigar smoking woman who happened to be the Governor of Connecticut at the time. My Mother didn't smoke cigars, however she thought it was cool.
A couple of times per week my mom would bring me to see Sigrid, as she was my mother's mentor. We had a good laugh when we realized the namesake as Sigrid recalled stories of the war and a woman's role in a man's world. That biological relation had been a friend many years before. There are coincidences in this world.
I was rather precocious at the age of ten and would invariably skip out of the house, say hello to Clarence, Sigrid's minder, and wander over to the river, past the old Westport Library on the corner of Post and Main. At that very corner there was a park bench where heroin addicts would nod out. It was called Needle Park and yes times have changed.
Walking across Jesup Green where the hippies were sprawled out mingling with the black leather clad bikers, I would skip up the little hill overlooking the Saugatuck River to the spot where the new Library now stands. It was a landfill back then and the funny thing is that they had a magazine section even then. A huge metal container filled with thousands upon thousands of discarded magazines. At ten years old there was only one kind of magazine that I was looking for.
Now 30 years later I make the journey in reverse. I have a workshop across the street from the old landfill, next to the site of the Yankee Doodle Fair (100 years and counting). I cross a little bridge from the fairgrounds over to the library parking lot. I do a quick scan of the printed headlines in the magazine section. I stroll across Jesup Green, no bikers. Pass by Needle Park, entrance to Guess Jeans (good tenant). I make my way into the old library building for a Starbucks. I stride along the river behind main street, over to and across the parking lot where Sigrid had her house and gardens right up to an adjacent lot behind the church where I manage residential modernizations to the only house in Westport with five legal kitchens.
In the most important ways, Westport is still the same. Train to NY, good schools and low crime. Not having movie theaters downtown has changed the dynamic along with the fact that most moms and pops are gone. But there were always women's clothing stores on Main Street.
It is interesting that in the recesses of academe there are a few Galtonian souls studying the psychology of music empirically. One thrust pertains to analyzing both speech and music according to pitch perception; how we view music and speech may be quite similar.
One finding, for instance, is that pitch is related to perception of social dominance and submission in both speech and music:
A commentator on the latter article notes that you can accurately predict an animal's size from its pitch.
Do markets have pitch and do they invite psychological responses with messages of submission (come hither) and dominance (threat)? Could we explain behavioral finance phenomena in the same terms as behaviors in the wild, communicated by the pitch of animal sounds?
It's a fascinating literature. Rhythm (shifts in frequency of ticks) might just be a consequence of pitch, as speculators respond to market communications. Perhaps it's no coincidence that rising markets are so inviting; falling markets so threatening.
Todd Tracy writes:
Emotional stability in musical rhythm goes a long way on the road to complex weaving of interactions. It is best not to get too carried away with the music as it is occurring and to keep an observant eye on possible upcoming change ups in the rhythm, however, not to be so observant as to get cold.
In my capacity as a producer of commercial types of music one of my most important tools is the use of tension and its undoing. I would tend to think that as human beings we would react emotionally to the tension in a universal way, the shiver that runs down your spine when you hear a section of a particular song. Breaking away from the expected syncopation in such a way as to capture the attention of the listener, not as a total distraction but as a way to lead the listener into the enfolding polyrhythm. One cool way to capture attention is to have the band just stop in the middle of the verse, for one beat and then continue on as if you never skipped a beat. You can usually only get away with that one once per song.
A technique I have been using for awhile to further the management of syncopated air-pressure is the use of a "ghost track". Rather like an "invisible hand" simulation in that music is played on top of a prearranged rhythm and then that rhythm is removed from the mix as it were. The ghost track can be a drumbeat, a whole other song or just about any kind of rhythmic audio. Tempo and rhythm modeling can help the music to feel more spontaneous as even the best musicians will tend to play up to and around the beat. After the original beat is removed the music is left precariously dangling on its own. So thereby combining multiple musical performances that dance around a beat that is not there provides a sophisticated allure.
Adding random elements in a sprinkled fashion music production could be like BBQ. Much testing is required. After I finish many performances I will always look around for other drum tracks of the exact same speed (tempo) and slip in and review many beats just to see what I might be missing. The question can become which track is the ghost track and which is actually the track. Many of these questions are left for the final mix in which a systematic top to bottom approach is always the way to go. For instance the kick drum is the first level set so that every vibration is set in relation to that level, the snare might be second followed by the bass and a rhythm guitar or keyboard. Next the lead vocal followed by high hats and solos. Special effects are always last.
There is a direct correlation between understanding rhythmic vibrations in music to market tension. It is the ability to absorb the tension in a cool manner. When a random gyration begins to make sense my emotional response is to trade because I feel that I am in sync with the mind of the mistress. By stepping outside of the song in my mind I can see the vibrational landscape in a more objective fashion.
It is a duality of experience to be able to hear the music in my imagination and then to create those exact imagined vibrations in the same split second. The markets are like songs just begging for solos. The unrealized vibration that we can imagine in the price changes are calling us to jump right in and start soloing, however if the ghost track is removed after you have jumped in you will find yourself quickly hoping for the song to end.
Jimi Hendrix was great in his ability to start playing a different rhythm in the middle of a song and to stick to it even if the drums and bass were doing something different. So too, reading all the market tensions but to not be drawn in by the emotions, so as to coolly carry out the plan. The tricks that a composer will use to get the listeners attention are similar to that of the mistress. How far can Robert Plant stretch that note? How far up can the price go?
Jim Sogi comments:
One thing I've noticed about rhythm is that you've got to feel it in your body. If you are busy counting 1,2,3,4 in your head, you've already missed the beat or it starts to get mechanical sounding and stiff.
Sure it can be quantified, sliced and diced, and put into numbers, but it is only the hours and hours of practice, of feeling and living the music that mean a musician can feel the beat. The rhythm is more than a count, there is an unquantifiable element that allows it to swing, to move in and out of the beat, a fraction before, a fraction after, and pulsing and changing in unpredictable cycles. It is what gives live music its life. It is why a canned computer drummer sounds so dry, so dead and uninspiring.
Hours, days, years watching the markets gives the same feel for the rhythm. This is not to say that quantification and study will not give understanding about the structures, the chords, the main time signatures, but the discretionary element to me is an integral part of the process that numbers alone can not totally replace.
Kim Zussman adds:
It isn't too difficult to follow established rhythms and melodious sequences. What is hard is to recognize changes the first notes of which sound familiar and sweet, but devolve rapidly into deadly arrhythmia.
Normal sinus rhythm > Ischemia > Inverted T-wave > Ventricular tachycardia > Ventricular fibrillation > asystole
Will Kenney offers:
I agree that you don't have to count simple forms, like blues or AABA stuff, that is so internalized that not much thought is required. However, it's often enough that someone puts some complicated music in front of you and then you'd better be counting. the challenge then is making the music really breathe while having to pay close attention to the page. at the end of the day the slice and dice of it all is very important. it's the command of the tools that allows the most freedom and puts you in the place of getting a groove together.

The musical scale that Pythagoras invented and that forms the foundation for all Western music is based on relationships between small integers. Both the frequencies of musical notes and the intervals between them are ratios of certain integers, as follows:
Scale of Just Intonation
Note C D E F G A B C'
Frequency 1/1 9/8 5/4 4/3 3/2 5/3 15/8 2/1
Interval 9/8 10/9 16/15 9/8 10/9 9/8 16/15
How could similar relationships be uncovered for the S&P? As a first step we might force all S&P daily moves into bins one point wide, that is we could call all moves of 1.0 to 1.9 points "one point moves," and so forth.
We calculated the number of occurrences of each integer move, and also the number that would be expected if we assumed a normal distribution having the same mean and standard deviation. The result may be familiar to some readers but new to others, so we show it here:
S&P Daily moves in increments of 1 point

The main features of the distribution as compared to the normal are: an excess of small changes (say from -6 to +6 points), a deficit of medium sized moves (of about +-16 points) and a modest excess of very large moves (+-35 points or more). A description in terms of these three features is a better one, in my opinion, than simply focusing on the size of the negative tail (as too many people do).
From Laurel Kenner:
In mathematics, Dr. Castaldo is on Parnassus and I am on the "Gradus ad." I do know a little about music and writing, and so I will nevertheless venture to observe that Pythagoras did not actually invent the musical scale. As Stuart Isacoff puts it in his masterful book "Temperament":
"Pythagoras's discovery was that the most 'agreeable' harmonies [e.g., the octave, fifth and fourth] are formed by the simplest kind of mathematical relationships. If the vibrations of one tone are twice as fast as the vibrations of another's, for example, the two will blend so smoothly the result will sound almost like a single entity [he is referring to an octave]. The separate constituents of this musical marriage are oscillating in the proportion 2:1."
Closer to our day, Helmholz wrote that consonant tonal relationships are embedded in the essential physical structure of notes — the sound waves. Look at a graph, and you'll see greater spikes in intensity around the octave, fifth, fourth, etc. These spikes are known as harmonics. Their intensity levels depend on the shape of the instrument that produces the sound, and the resulting mixture contributes to the distinctive sound of each instrument.
(Hold a bass note on the piano down and strike the same note, stacatto, a few octaves higher and listen closely — you'll hear sonorities of tones still higher. Or experiment with harmonics on a vibrating guitar string.)
The market's ever-changing significant levels might be viewed (heard) as harmonics of past turning points. The Chair's insights on the continuing psychological impact of catastrophic events would seem to be in this genre.
The mathematical relations found in music are tempting to apply to the physical structure of the universe, and people have done that at least since Pythagoras. But I will leave that to the physicists.
Todd Tracy adds:
We might be socialized to market intervals in much the same way as to musical intervals. I found this interesting.
Evolutionary Effects by Robert Fink, 2004
General human evolution has provided us with voices that are acoustically musical, and with ear receptors that are appreciative of, or attracted to, acoustically-musical sounds (i.e., not noisy). Why this evolution?
Without these physiological capacities, then:
* Mothers would not coo to their babies; nor would the babies love the sound of it;
* Nor would evolution of language and the socializing sounds of the voice have been as possible;
* Nor would the noisy (i.e., not-acoustically musical) sounds from any nearby destructive event or attack, or of the sounds of breakage, screams or cries of pain, have served as a noisy warning [unattractive or repelling] to alarm or alert us — Some sounds make us come, others make us run….
And, as a result, our collectivized survival might not have been as efficient, and we could have gone the way of the extinct Dodo.
All those same capacities [regarding being able to distinguish noise from "musical" sound] also served to allow the development of musical systems to arise and evolve wherever there were curious people with time to play or experiment with the stimuli around them.
Tom Ryan extends:
I find this Pythagorean scale discussion fascinating and have thought about various applications of musical scales and notes to market prices often over the years. Pythagoras believed the universe was an immense monochord and many of the Pythagorean teachings at Crotona are remarkable insights, especially with respect to what we now call string theory.
Pythagoras believed that by studying music mathematically, one could develop an understanding of structures in nature. One of the more interesting aspects that I have found in this is the lambdoma table, which is a 16×16 dimensional matrix of ratios starting with 1/1 and ending with 16/16,
1/1 1/2 1/3 1/4 1/5 1/6 1/7…….1/16
2/1 2/2 2/3 2/4 2/5 2/6 2/7…….2/16
3/1 3/2 ………..
16/1 16/2 16/3……………….16/16
The lambdoma is composed of two series. The first represents the divisions of a string which represent frequencies or tones. The second level represents harmonics. For example the first 16 harmonics of C are 256 hz (C), 512 hz (C), 768 hz(G) 1024 hz(C) 1280 (E) 1536 (G) 1792(B-) 2048(C) 2304(D) 2560(E) 2816(F#) 3072(G) 3328(A-) 3584(Bb-) 3840(B) and finally 4096 hz (C again since 4096/256 =16/1). This series represents the overtones or partial and whole harmonics of C and are represented by ratios in the table
Through the ratios one can study other types of natural structures as well. Botanists in particular have studied geometrical structure and many plant structures (leaves, flowers) have been noted to be geometrically developed in consistent ways where the key geometric ratios fall into a contiguous grouping or overtones of a fundamental, i.e. a pattern of squares within the lambdoma matrix. Leaves for instance often have simultaneous ratios of thirds (5:4) and fifths (3:2). The Renaissance studies including Da Vinci's notebooks note that the human body develops along particular lines as well, namely an abundance of major sixths (3:5) and minor sixths (5:8).
These whole number ratios or pattern of harmonics, as Laurel noted, form the basis for musical scales,
Major sixth 3:5
Major third 4:5
Minor sixth 5:8
Minor seventh 5:9
Major second 8:9
Major seventh 8:15
Minor second 15:16
The question is whether specific harmonic patterns occur at times in the market and whether these can be quantified in some way. Victor discusses market prices as music in his book EdSpec.
One way would be to classify movements as ratios, and see the patterns of ratios as they unfold, classifying movements in price as patterns on a scale or within the lambdoma. From that one might be able to find a few meager predictable patterns. But there is a problem with this: to calculate ratios in a contiguous strip of real time prices one must arbitrarily choose reference points in order to calculate the ratios.
This means that there is a substantial level of subjectivity in developing the ratios from which the patterns can be studied. But one could arbitrarily divide the day into segments and look at ranges or deltas within those segments (say 30 minutes) and then calculate ratios of adjacent periods. There are probably an infinite variety of ways to segment and calculate ratios and therein lies the dilemma.
Gangsta rap that glamorizes violence and demeans women is an insidious cancer overtaking our culture. I believe that the dominant thought that you hold in your mind will manifest itself in your life in some form of outward reality.
St. Louis, once a fine city, is now really several distinct microcosms. North St. Louis city and East St. Louis are shells of their former selves. They are the living, breathing personification of statist government policies, which makes me wonder: wouldn't that then make gangsta rap simply a symptom of the more advanced stages of the cancer that statist policies bring about?
On one hand you have the cancer of statism destroying inner city communities, and gansta rap is merely a symptom along the way — like an organ system shutting down in a body riddled with cancer. But in the suburbs the latent cancerous stage of statism manifests itself in the form of the "COPS" genre.
I wonder: Are all societies doomed to slow cancerous degradation? Is it somehow part of human nature that over time, prosperity leads to further and further degradation of morals and our sense of right and wrong?
History is rife with case after case of societies' collapsing because of hubris. Is this really the cancer that effects the soul of man and destroys us slowly and patiently over time, without our even noticing it — the boiling frog?
And if this is the case, how do we profit from this long-term trend? If I can't change the world, I want to profit from it while I'm here and leave my family a legacy of wealth, both in financial terms and more importantly in philosophic terms, so that they have the ability to maintain and grow the wealth legacy that I've begun.
Todd Tracy adds:
Stevie Wonder had a couple of songs that highlighted some negative aspects of society: Living For The City and Frontline.
The record companies will take the line that the market decides who gets the promotion budget, just as their big brother the films studios do. As far as the suburban kids buying the stuff, I don't think they really get into it. The rappers just do it to make money.
With gangsta rap music, it is hard to tell which is the cause and which is the effect. In all cases it brings to light an awareness of things that need to be changed, and music is always a perfect tool for the job. Sometimes it comes down to who has the hardest-core believable vibe. Stevie was hardcore in his day. The way that he produced his records was badass.
The market's repertoire of rhythms extends past human grasp. Sometimes it seems to make no sense at all, at least to me.
Sometimes, things seem to become clear. Just as in Afro-Cuban music, a strong voice - the "mother drum" in bata - dominates the counter rhythms of the smaller drums, sometimes the Fed's announcements dominate the backdrop of lesser voices — Chinese monetary authorities, fixed-systems followers, and what have you.
Earnings season has a peculiar rhythm. But it's ever-changing, based on which companies are strongest at the time.
One quality the market shares with music, good music, anyway, is "always the surprise." Bach, Mozart, Beethoven were all masters of deception and expert at weaving rhythms across bars. Beethoven's sforzandi, unexpected sharp accents, and sudden pianissimos, will be appreciated by all traders.
Back in the '90s, when I was the editor for the stock coverage, a humorous bond reporter at Bloomberg had a saying when stocks had yet another amazing jump: "Stocks ONLY GO UP," he would say, rolling his eyes knowingly, meaning just the opposite. No good musician plays loud all the time.
I am thinking of ways to quantify the rhythms of markets. Instead of looking at what others do, critiquing it, and then augmenting, I thought I'd just take a crack at thinking of it my own way.
Music rhythms would seem to be a good starting point. The rhythms that kids are taught are those they can step or clap or slap to. They can be fast or slow to start with. And I would look to see if the number of moves in a minute is fast or slow and how this changes. The slapping would involve moves from separate markets occurring in the same time period. When we step, the first step is the accented one and that's a good way to look at moves within a period. Is it the first step that's always the biggest, and what happens when the second or third step in a period is the biggest?
I would look next at the rhythms of big moves. They obviously are reversing now, with some big Tuesdays: February 27, -58; March 8, +22; March 13, -28; and March 20, +8. Naturally this kind of stuff isn't predictive in general or else it would come out in the standard time series programs. But on occasion, it comes back and forth to an inordinate degree and the question becomes how to find it.
Animals often migrate at the same time of year to the same places even when transported geographically. One wonders if the migrations of markets after big moves have a fixed place in the price firmament that they go back to. Or is it just in time, like the conventional seasonal stuff that one can expect from the migration? Last year, prices went way down in May and migrated back the last part of the year. This year the migration started in February. The month ended with the three old bags ("a woman her age would never show her posterior to a camera") acting in concert with the rhythmic release of the perennially bearish message from the Sage.
The rhythms of political announcements always seem to follow a circular path. They start with a loose cannon doing something that hits into something else. Then others join the act. One typical sequence involves worry about inflation, based of course on a preview of an upcoming release, then the release of the number, then the big bond fund guy saying he's bearish, then the perma-bears finding other inflationary things, then the opportunistic movement in certain nations that benefit from this or that energy price, and finally the rhythm ending with the release of the next number, or the quieting influence of an open market meeting.
Hoaglin has some great diagrams of rhythms in the body. And the body has different rhythms that it responds to as molecules bounce into each other and create disturbances throughout other more complex molecules, thus upsetting the usual homeostatic methods. One market makes a big move, perhaps silver, and it spills over into others in a rhythmic sequence, perhaps an up in energy, and then a decline in stocks. It's not over until the initiating market has its move back down as was the actual case with the recent bloodbath and recovery, which seemed to have the elements of rhythm of all the ones I mentioned.
Of course, the rhythms have to be combined with the melodies. The speed of the moves has to be counted with the steps between those moves, sometimes big and sometimes small. And I like the way they quantify melodies in the Joy of Music and in the statistical studies of music intervals that have so much resonance with markets.
A more humdrum approach to rhythms, which I take, is to look at the rhythms of patterns. How often do the 3-day moves with their eight possible directions: —, –+, -+-, -++, +++, ++-, +-+, + — repeat? Is it a first order Markov process vis-a-vis these eight patterns, and what is the correlation between the closeness of each of the last three moves to these three patterns, and future moves? I recently ran some rhythm stuff with open, open to close, and open, and found some ministerial randomness with t's all below one, but enough evidence of non-randomness to get me thinking about rhythms on the whole.
I know enough about rhythms to know that they feel like the basic rhythms come from within the body, like the beating of the heart, and they can model it with rhythms based on the mathematics of African rhythms. Whatever quantifications they are making in bringing African rhymes and Latin rhythms into the heart beat problem would seem to be a natural for extension into the market.
I am fortunate to know someone with perfect rhythm and she is the coeditor of this column and I am going to ask her how she would try to trade in the market if she knew nothing else but markets. Perhaps other musicians with perfect rhythm might have similar expert opinions as to where market moves would be going based on their knowledge and oneness with rhythms in markets. Certainly these experts would be more prone to give good calls than the eminent people who have passed the tests of the mystical societies of America that are licensed to forecast the market.
The market's open now, and I haven't read any of the dozens of books I have on rhythms lately, but after I do and study it on the Net, perhaps I'll have some other ideas. For sure, my colleagues will be able to augment my preliminary fast ideas on this and guide others and me in proper directions.
George Zachar comments:
Perhaps other musicians with perfect rhythm might have similar expert opinions as to where market moves would be going based on their knowledge and oneness with rhythms in markets. Certainly these experts would be more prone to give good calls…
An interesting way to test this would be to submit representations of various tradeables in various time increments to musical prodigies who are naive about markets. I am thinking particularly of junior and senior high school students, who could have sufficient musical training and experience, without having been exposed to what passes for financial and economic wisdom in the popular press.
Ken Smith writes:
In harmony with Victor's piece on music, rhythm, I attempted to write a melody with three notes. I am having difficulty conveying this little ditty because the note symbols for music are not available in email text messages.
I've tried before to get symbols to end up as they were written when they appear after I've sent them. Somewhere in the Internet circle symbols sent in email get warped, become hijra. Meanings are thus distorted.
So maybe someone can help here. The musical symbols for this simple melody would be symbols for the Dollar, Mark, and Yen, just three notes.
Create a melody using these notes - they are real notes, after all. Then choreograph a dance for the melody. Add lyrics. Create permutations and program computers to trade dollar, mark, yen - according to the melody.

Everyday I am inspired by the list and become more humble. In the business of music I had done well being rather sure of myself. That confidence came about from having practiced hours daily for 20 years. And even then I had much to learn. Afro-Cuban percussion was one of those things I knew nothing about until the day that my roommate brought home four percussionists. I didn't know at the time that they would be living and practicing in my living room for two years. And yes, they had many percussionist friends. The neighbors didn't seem to mind. They played all day, ten drummers strong, and then went on to their gigs at night.
One guy, Jacques, studied African rhythms. His guru was Babinga. Another guy, Blake, studied Cuban fusion. His guru was Giovanni Hidalgo. Davey was into Indian drums, Egyptian bells, and all sorts of experimental world music. Josh was a well-rounded guy who did it all. Their friends were mostly jazz funk kit players.
At any rate, I was doing 80 hours a week at the record company but on occasion they would let me sit in with them during rehearsals. When it came to the Congolese and Senegalese rhythms I had to learn to play the pattern given to me and not concentrate on the patterns the other guys were playing. The African stuff doesn't resolve like western music. Each part is simple; the complexity comes from the layering. Euro rhythms resolve every measure. Four beats to a measure at tempos ranging from 60-130 beats per minute. The African stuff would resolve many measures out, like ten equivalent western measures. It felt as though it was random until, with incredible anticipation, the resolution was at hand.
The Latin stuff was different in that the Cubans, Haitians, and Puerto Ricans had fused the African rhythms with western melodies. The most important part to the rhythm was the clave (wooden sticks that ring out when struck). The clave would be a simplified version of the rhythm. Then came the congas. They would play a rhythm called a Tumbao. Again, you had to concentrate on your part but synchronicity was achieved and resolved after just a couple of measures.
I was completely humbled by all that I did not know. But soon, through repetition, I found I had a whole new arsenal. These guys would play until their hands bled every day as they developed the incredible muscle memory needed to counter western rhythmic intuition.
Now the straight up rap beats are simple in that they are looped (kind of like rock music). But it is the anticipation of that resolution that concerns us with the market rhythms. In hip-hop the kick is on the one and the three; the snare is on the Two and the Four. The snares are played late to increase the anticipation. This lateness is the most important part, in fact, so important that rap artists actually consider the two and the four as the one and the three.
All of the rhythms resolve. There are problems in programming the beats in that there is a finite number of places to put each beat within a measure (460 ticks per beat) and the velocity of each beat is set at a value 1-127. We can, however, increase the resolution by doubling the BPM and by fine-tuning these anticipations and resolutions. I am studying the Quantlet Booklets so that I could one day break down the market rhythms as is being shown to me by the list members through the graciousness of Victor and Laurel's benevolence.
As far as what I think the S&P index will do from a musician's perspective is resolving to 1450 after channeling a bit more.
Laurence Glazier writes:
It is very tempting to apply my knowledge of music in selecting trades, though I like to follow grounded mathematical principles at this stage. I would note that much of what we consider the theory of music was derived by the posthumous analysis of the works of the one and only JS Bach (the Moses of music?), which like much technical analysis is seductive but not necessarily predictive. I work on the principle that part of this analysis represents laws of musical reality empirically testable, but not in the normal way. As Leschetitsky said, "Where words end, music begins."
Of the technical analysts of music, Schenker is particularly interesting, while those who have enjoyed "The Glen Miller Story" may have observed the appearance of another significant analyst, Schillinger.
Having said that, I believe the analogies with market rhythms, while not necessarily predictive, would be very valuable as part of a real-time virtual reality program reflecting the current state of play in the markets, and pose the question whether users of such a system would do better if they were more musical.
Victor Niederhoffer adds:
There is something rhythmic in the moves of bonds and stocks together, over and above the comparative rates of return that the Duo and Dodger have quantified. And it's like the monkey rope that Melville describes, where when one goes down and the other has to follow. But there is much thrashing around as the turbulence from the whales temporarily overrides the inextricable bond.
And in that context the bonds, after setting a 19-day low at 11,202, are still up 2/3 of a point or about 1/2% on the year. And the stocks, after setting a 19-day high at 1445, are up about 1/2% on the year. Regardless of that it's what I used to call an ugly day and the rhythm is very bad for both when a big decline in one occurs in conjunction with a big rise in the other. Something has to give, and as Berlioz would say in reviewing Beethoven, you know it's going to return.
George Criparocos writes:
The two days preceding the big note (02.27, the resonant, memorable one) had the bonds making a rhythmic intro analogous to what is expected when the largest instrument of all, the bass, announces a change in melody.
Since then, the contrabass, cellos, and violas (10s, 5s, 2s) are keeping the resonance, while the bass returns. The clarinet (Yen) is hanging around its 200MA set like a rope, refusing to let go of the anticipation and the piano (stocks) are all over the pentagram, in 1/16th intervals: four days low, four days high, four days flat, four days high.
The rhythm seems to be analogous to a symphony, lets say in F major. The allegro is in progress and I anticipate that the andante should follow in a molto mosso way.
James Sogi adds:
Todd's analysis of African rhythms resolving over eight or 12 bars or multiples rather than the simplistic four beat 16 bar square "rock" structure is right on the beat.
One of the most basic rhythms popular in the blues is called the shuffle. It is a short-long, short-long, short-long, similar to the heartbeat or train on the track, da-dum, da-dum, da-dum. This basic rhythm underlies many more complex patterns.
Applied to the market after a small beat, there the long bar, the "shuffle." The count often does not capture the rhythm, just as European musical notation does not carry information relative to rhythm. That is an odd omission. A shuffle might be notated as straight quarter notes, but played as doted quarter and eighth note sequence and designated as a shuffle, all the musicians know right away what it means.
The rhythm can get behind the pocket, giving a laid back feeling, like the end of last week. Or the rhythm can get ahead of the beat, like disco, like last month's drop.
The middle of the pocket of the beat is the march's oom-pah, oom-pah, even beats. The rhythms will swing from behind the "pocket" and give the music different feels. This is very difficult to quantify because the interaction of the multiple players is complex and the "feel" is a subtle thing to capture. Musicians know this.
To capture this in the market is a difficult matter. The main difficulty is the time structure. A structure stretched out over weeks is difficult to feel for human rhythmic sense as our rhythm is based on the heart and walking, and resides in the feet and heart and head motions. So it's hard to feel the market rhythm without condensing the time and looking at the numbers or speeding it up on a replay as an interesting exercise.

From Vincent Andres:
I am thinking of ways to "quantify" the rhythms of markets.
I didn't test it yet (will probably do so sooner or later) but the already known track of Hurst/Hölder/ exponents seem to me to be a possibly good piece of measurement.
Another possible tool could be wavelets.
Also, I recently came across a paper melting wavelets + Hölder curves : L'analyse par ondelettes, in Science, Vol.119 Sept. 1987. Yves Meyer, S. Jaffard, Olivier Rioul. The paper is in French. Very certainly progress have been made since this paper was published.
When a helicopter has an engine failure the pilot will make use of “autorotation” whereby the upward motion of the airflow through the rotor will cause the blades to continue spinning allowing for a safe return to earth.
However, sufficient altitude is required to avoid a hard landing. In a helicopter altitude is your margin. The intuitive notion that a helicopter without engine power will fall out of the sky is false.
There are a lot of correlations to the markets in flying a helicopter, the most obvious is that one tends towards overcorrection.

With all the movement of the EURO/USD getting bashed about by scheduled events, round numbers are frequent resting points. Right now we are at 1.29. Coincidently it is 1:29 A.M. Monday New York time. The European traders will be waking up soon and they have their own brand of fake out maneuvers, usually beginning around 2:30 EST., and within a couple of hours, their true intentions become known.
There are lull times in-between global market opens and announcements. During these times, there is drift. It can be scary as the drift moves in-between the round numbers, but gravity is often predictable. The scary part is when the drift becomes significant and time elapses into a fundamental zone.
For instance, a drift approaching 1.2925 could mean that we have a new resting point and our gravity to 1.29 is no longer as likely. Anything under 12 pips is not as significant. However, I hate going short at 12 above my root note and then have time bring me into a fundamental zone before the gravity occurs, so I have to look at the speed of the drift. Slow drift is the hardest to read. Rapid drift can give insights. Change ups in drift speed call for sophisticated timing. I find that it's better to wait a couple beats for a rhythm to be established. However, that rhythm can be hard to count on for any period of time, which brings me to the psychological fake out mode. When this occurs, it is best not to be caught in the switches and stick to my original assumptions.
My cousin just gave me his S-PLUS CD. I want to develop calculations for this drift speed as it is relative to the resting points at exactly this time of day. I am a Jr. programmer and am just now learning to count. I would be grateful for any ideas along these lines. It is now 2:11 and no drift at all, so there is no reason for me to open a position until they wake up across the pond. I am going to start by collecting data for an excel spread sheet with columns for one minute time and euro price. Oh wait, 1.2909 at 2:34. Too close to market open to risk it, my drift window has closed.
In my band, the big joke is that the talent I lack as a guitar player, I make up for in equipment. Anyway, while listening to DVDs of famous guitar heroes on advanced techniques, the guitar master, Eric Johnson said the following about chords: "Don't look at chords as rigid patterns, rather try to think of them as hidden melodies." The idea of structuring the chords as a fixed system, so to speak, takes away some of the creativity and spontaneity. Rather, use the chords to add 7ths, 9ths, 11ths, augmented 4ths, invert them, move them around the keyboard, and use substitute chords. Often for example, a B minor will sound the same as an E6 and so on. From these substitutions and passing phrases, melodies which are hidden in the structure of the chord emerge to the ear. There are far more advanced musicians here such as Flam, Klosek, Glazier and the new spec, Todd Tracy, so I will defer to them on this. But the idea is that market patterns should not be viewed as rigid patterns, but rather as hidden melodies. As the day trades out, the variety of bars is endless and new. Rather than lock into fixed systems, it is good to see the hidden melodies in the market music, let them play out, and hopefully get in tune and be able to play along without being totally out of time, and out of tune. Figure out the market's scales and chords, and like Maria in the Sound of Music, once you know the notes to sing, you can sing almost anything. Ear training helps the musician hear what key is being played, what chords, and what scales without looking at sheet music, and only by listening. Market training, by watching it everyday, seems to help the training of the eye as well.
Todd Tracy comments:
I agree with Jim. There is no telling if a model shift has occurred without hindsight. Certain musicians or markets players might have tendencies and regularly use familiar notes to bridge the music into another scale. The Euro cruising past 1.30 could be the root note for a new song or just a suspended 4th of the 1.2950. However, there is always that moment when the mistress has to decide whether she's staying in G major or going for D major. There is no d flat in G major, so if you hear that note, the change has occurred.
Scott Brooks adds:
As someone who has made a living for years with TA and pattern recognition, I can relate to this. Since I've added quantitative analysis to my management processes, I've been able to empirically test my prior pattern recognition skills.
What's interesting to me is that I've been able to better fine tune patterns by testing them, and now, I see them in a whole new way. I see things that I wouldn't have seen before. I'm a very visual person and the charts really help me!
As I've said before, my charts are just a visual representation of my calculations.
Some people find it helpful to look at blue prints. Some people like to look at what the finished building will look like. Regardless, quantitative analysis is required to create whatever visual image you prefer.

Hunter and hunted or predator-prey relations are pervasive in the animal world. We're accustomed to observing and reading popular summaries and videos of the dynamics and techniques of survival for such pairs as lion & gazelle, wolf & squirrel, fox & lynx, coyote & seal, osprey & smelt, pike & minnow, and spider & fly. Such studies have been extended to romance and health among humans. Predator-prey relations are also common in markets. For example, the relation between market maker & day trader, dealer & ephemeral trader, flexible & inflexible, large trader & small trader, informed & uninformed, vig taker & vig payer.
Many studies in the field are based on the Lotka-Volterra model. This is a set of simultaneous differential equations relating to the rate of growth of the predator and prey populations to each other. A typical set of equations relating rabbit growth to fox growth states that dr/dt = ar-brf and df/dt = ebrf-cf where a is the natural growth rate of the rabbits, c is the death rate of the foxes, b is the death rate of the rabbits whenever they meet a fox and e is the proportional gain in growth that a fox gets from eating a rabbit.
Such equations do capture the main idea that as the rabbit population increases, the foxes gain in number because rabbits are easier to find and eat, and this provides a homeostatic mechanism to stabilize the rabbit population. Similarly, as the rabbit population declines, the number of foxes decreases because they have less food, and this helps increase the rabbit population which in turn tends to increase the fox population. As might be guessed, small changes in the assumptions of the model, such as time delays, lead to widely divergent behavior involving cyclicalities, instabilities and sharp changes in the dynamics that do not correspond to what we observe in most real-life populations.
A similar critique could be made of the two other standard methods of studying predator-prey relations, which are the functional response curve and the optimal foraging theory. The basic regularities there are that the costs and benefits of gaining prey vis a vis future reproductive success determine the extent and energy with which the predator seeks the prey. The key dependent variable is how much the predator eats as a function of the difficulty of converting the prey into food. An increase in the search time, handling time, or consumption time, reduces the predator's desire to eat. Certainly this leads to insights. The problem here is that all these parameters are subject to estimation, and they are interrelated and subject to different hypotheses as to their function.
Methods of studying the factors that enable predators to be successful have always been important to me as I, like other numerous individuals not at the top of the food chain, are often prey to much larger predators. I have often wanted to learn how to avoid capture, and even considered the possibility of sometimes turning the table on the predators and bagging them once or twice just to make the game a little more even sided. Thus, when I came across a cover story in Outdoor Life titled "Predators' Deadly Tricks," which describes how hunters go about capturing the most elusive predators in real life such as the coyote, the bobcat, and the mountain lion, I was very attentive and decided that I should try to devise principles from the practical and theoretical literature that might help other prey like me in their incessant battle with those who would devour them.
- Signaling is key.The signals that the prey send out to show that they are not easy to digest prevent the predator from even considering attacking, and this saves much energy for the escape. Colors and scents indicate that the prey contain poisons. Stotting, the jumping behavior of gazelles when about to be chased by a cheetah, indicates that they are very mobile and not worth eating. Indeed the essence of the article is that the best way to attract a predator is with an electronic duplication of the distress call of its enemy. Amazingly, the coyote will often show himself within one minute of hearing the rabbit's call, especially when it's made with a "Foxpro FX5 that has a 200 sound capacity, one gigabyte of memory, recall buttons to switch between sounds, remote control functions, and a 700-yard range. Less than a minute later (after the call), a pair of coyotes charged in and we handily dispatched them." Market prey often indicate that they are ready, willing and able to defend themselves by the placement of limit orders in large size, but cancel if they are near just to prevent the larger predator on the other side from even thinking of going after them. The talk with your counterparts is how much more is available for adding to my line when you well know that one more grain of salt would be enough to topple you over.
- Vigilance is essential. The herding animals all find that 100 pairs of eyes with 50 always awake are enough to warn them of danger. Noses are always sniffing, ears are listening, and the antennae are always feeling. Indeed, some ducks can sleep with one eye open so as to never be victimized by a surprise attack. The hunter uses a telescope so that he can always perfectly see the adversary. He never lets the prey's vigilance work to his advantage by approaching stealthily, parking his equipment a mile away from where he's going to hunt, and setting up in a blind with proper camouflage. The prey in the market doesn't leave the market for a moment, as that might be the time that the enemy attacks.He cancels all orders when they don't get filled so that a surprise news announcement that's worth a limit move won't catch him just a few ticks from the last price. He has his computer set to wake him, which buzzes around in his private area so he never sleeps through a dangerous situation or lets the predator devour him totally.
- Deception is essential. My goodness, the moth blends in with the bark and orients with the grain of what he's sleeping on. The flies disguise themselves to look like bees, and the octopus can change 100 colors in one second. The spider uses a million deceptive lures to entice the fly into its web. The golden orb weaving spider spins a web that's so enticing that even when a bee breaks free, it will dive right back into it after it has escaped. (I am reminded here of the system player who, after a very bad trade on one side, doubles up on the other side for the next trade.) The chapter on deception in Education of a Speculator details other areas of deception in the world. "Quality camouflage is a must; select the pattern that most closely matches the foliage and landscape." Whatever you do, don't make any news. As a prey trader, I don't even like to type out that I'm thinking of exiting a trade, for fear that a predator might have my screen bugged or that the keystrokes are programmed to signal my intention. I never let the other side know what my stop point is because I know that it will always be hit. If I'm really hurting, I'll try to act 5,000 times stronger than I am, and I won't even begin to reduce my position by one contract for fear that my camouflage will be found out.
- Proper equipment is a must. Predators are constantly sharpening their claws and teeth. Prey must always practice escape maneuvers. Over many generations, most prey have adopted advanced techniques of escape that include the full range of methods used by individuals in their cohort from the beginning of time to elude capture, be it poison, scent, or cry. Their bodies are perfectly suited to the escape in size, color, speed and strength. The properly equipped hunter, in addition to his Swaroski binoculars and Foxpro FX5 caller, currently has a Gerber Epoch Pack, a Stoney Point bipod, Cabela coverup pants, and, of course, the obligatory Ruger bullets in a Browning rifle, a Bushnell scope, motion decoys, and a set of shooting stocks.
- If all else fails, try the unusual. Be prepared to shout if the predator attacks. The proper equipment for the trader starts with a proper price feed, perhaps one that's within a foot of the source of the prices so as not to lose out by the speed of light that it might take to get to you one-thousandth of a light second away. Next, one should have a computer that's always set to trading and that isn't interfered with by email. Finally, have an office where no one can distract you from the job of survival with the cares of the world or a bill from the Service.
- Never give up. The cries of animals often save them from death. If nothing else, they serve to alert family members. The squirting of poison and the enlargement of the body is a common tactic of the caterpillar, and the gyrations of the weasel in extremis are often enough to ward off death. The hunter is told to scream if a predator attacks him and to have a spare set of guns and knives. As a trader, I try to follow the rules of a good competitor in sports who never gives away the last point of a game if there is still an iota of energy left in his body. There is always someone you can call on to help you fight back. On occasion, I've even asked a'la the Boy Wonder for the other half to help me out in a time of crisis, and so far the trust funds are still intact.
- I would recommend studying the literature on predator-prey relations by reading a few good books, following up on some of the hundreds of thousands of citations on the search engines, reading the Outside Magazine article in the December-January double issue and then trying to apply these techniques to make yourself impossible to detect, fruitless to waste energy on, and impossible to digest when caught. If all else fails, fight to the death.
J. Klein adds:
One Predator - One Prey; if it was ever so easy.
It is more like Many Predators - Many Preys - Many Parasites. Symbiosis. Competition among different parasites - how to maximize exploitation without killing the organism parasited. How to use a competing predator to one's benefit. Mixed situations: One is a predator and a prey at the same time but to different kind of critters. How a steady state equilibrium evolves.
In my opinion, however, we humans have already won nature's battle and rule the ecology to our benefit. We easily see through the animal world's tricks and catch them as we want. But the market is wholly made up by humans, who presumably have all been exposed for generations to nature's tricks and have become resistant to them. Situations like those that nature presents to us are no longer relevant, and we have moved to a higher level. It is a different game here.
Since we are part of the game, it is very difficult to see what is going on and much more how to manage it. It is said that even the big winners know how they did it and why they succeeded. It seems to me that those winning have more useful memory, are able to calculate more precisely, see the present and the future more clearly, can formulate better plans, and execute more rapidly and precisely. In the market, nature's tricks don't work any more. This is a play of pure and cold intelligence.
Scott Brooks comments:
I've thought about this predator/prey relationship for many, many hours as I was sitting in a deer stand and I have several thoughts on this issue. I'll share some in this post.
One of the biggest things to recognize in a predator/prey relationship is the opportunity that exists. One of the biggest things that we need to look at is the difference between instinct and reason. Whether prey or predator, if you are instinctual, you are acting out of some deep seeded genetic conditioning that causes you to run when faced with adversity.
Think about it. If there are seven lions chasing a herd of 200 gazelles and the gazelles had the ability to reason, they would say, "Lets stick together and as a group go over there and trample those seven lions to death." The 200 gazelles would win that battle, and probably over time could condition the instinctual predator lions to leave them alone. The cost of messing with those gazelles is just too high.
Think of an instinctual predator like a bear. Almost any bear could take a human if they wanted too, especially the bigger varieties like Grizzlies. Humans are simply not equipped to deal with them physically. But for the most part, we've conditioned bears to stay away from and fear us. That's only because we have the capacity to think and reason at a level that the Grizzly doesn't. We've figured out a long time ago that taking some animal gut and stringing it on one bent stick, and then taking another straight stick and putting a sharp tip on it, gave us the advantage. Then along comes names like Remington, Browning, Winchester, Anshultz, Benalli, etc. and the odds are stacked in our favor.
When I played poker back in the 80's, I looked for certain types of players to be at a table before I would play. They were the prey. They weren't thinkers. They were gamblers. They let the cards fall as they may and "hoped" that things would go their way. But they had no real system or methodology to identify when to hold'em and when to fold'em. Most of them could not name three cards that had been played and subsequently folded (I'm talking seven card stud). So they had no idea what cards were still available to be played or not. I can't even count all the times when I could tell what hand someone was trying to build or bluff me into thinking they had and yet had no idea that the key card was already burned in the deck because someone had folded earlier. I guess I was a counter of sorts even back then. I'm not sure that qualifies me as a counter yet, maybe it just makes me someone who paid attention and kept track of things.
These "gamblers" were hopeless gazelles at the table. I'm not saying that to be braggadocious. They simply didn't know what they were doing … they were nearly instinctual prey. They "needed" to win. They were always one card away from catching a break. They relied on luck. The reality for these guys was that the only way they could truly win was to quit and stop playing. Otherwise, ruin awaited them all.
Those are the guys that I played against. I did not play against other good players. If there was more than one other good player at the table, I would find another game. I had nothing to prove by beating another good player. I was there for one reason and one reason only: to win money.
For the same reason that lions don't usually attack other lions to eat, I was not interested in paying the price associated with trying to win money from other good players. The cost and risk/reward was just too high.
To apply this to the markets, it is important to figure out where the instinctual investors are playing and those that don't have a thinking system, and use that to one's advantage.
What are the masses going to do when "X" event happens? What is their likely "non-thinking" irrational emotion based response ("quick, run, the lions are coming").
Unfortunately, as I've said before, the masses left the markets after 2000, 2001, and 2002. They were burned so badly, and fear chased them away from what was very likely the greatest buying opportunity of their lives. It was like gazelles drinking from a stream and some of them getting snatched by an alligator. It seems to me that after a few have been snatched, that's the time to go get their drink … the alligators have enough food to last awhile now … and if nothing else, there is a few less alligators now patrolling the shores for food. The odds of success have gone up for the gazelle … but that's when they leave in fear.
So I will be that thinking predator. I will only fight battles that I know I can win. My goal is simple. To make money! That's it. I've got no ego in this and no axe to grind. I'm not going to challenge Prof. McDonnell in the world of options, or Prof. Haave in the world of commodities, or George Zachar in the arena of bonds or Vic in the world of index futures. They are simply more skilled and knowledgeable than I am in those arenas. I could be a predator in those worlds, but I would be like the Grizzly bear, and they would be the thinking human up on the ridge 200 yards away pointing a Win, and a 300 Mag at my vitals. That's a battle I can't win.
But there are things that I'm good, and there are arenas I can battle in. Since I only want to make money, I will only play in the arenas with the best risk/reward ratio for my success, and I will stick to those arenas (but I'll still learn the other arenas … and who knows, I may show up there one day and dip my toe in … but only when I think I'm ready … and then only with a small amount of money to make sure that I'm really ready).
So, Phil, Gordon, George and Vic, be careful, I may show up in your arena one day … and I'm a good stalker who knows all about how to properly deceive with camouflage …
Tim Humbert comments:
Over Christmas I heard a wonderful recipe for pike:
-preparation: gut and de-scale, rub rock salt and pepper onto flesh, squeeze some lemon juice, insert some herbs into fish, wrap in aluminum foil and cook for 30 minutes
-consumption: throw pike in the bin and eat the foil
Rick Foust adds:
The largest predators (e.g. lions) are much smaller than the largest grazers (e.g. elephants). The largest grazers have much longer life spans than the largest predators despite having inferior camouflage. Certain large houses come to mind.
Small grazing animals (e.g. rabbits) do not survive long despite having excellent camouflage. Their numbers are maintained by fertility (replenishment). New, poorly bankrolled traders come to mind.
Professor Sorin Solomon, of the Racah Institute of Physics, has produced some very interesting market models based on Lotka-Volterra. Here is his homepage.
He showed that a generalized Lotka-Volterra model for the market yields a truncated levy distribution for index returns!
See for instance his 1998 paper: "Stochastic Lotka-Volterra systems of competing auto-catalytic agents lead generically to truncated pareto power, wealth distribution, truncated levy distribution of market returns, clustered volatility, booms and crashes."
There are simpler explanations for TLFs, such as a random-walk with time increments that are variable rather than fixed, just like with real-world transactions … but I thought this was topical.
There could be one way to check the above, and that is the impact of random time between transactions. On Euronext, we've got a mechanism for trading very small stocks. It is called "fixing." One could compare behavior of such stocks to behavior of other stocks that trade continuously. One could also check the behavior of stocks that have moved from fixing to continuous trading or the behavior of the whole French market as it moved from all stocks fixing to most stocks continuous in the mid-eighties. There's also a possible comparison between London Gold fixing and NY COMEX.

Market Set Ups
While reading Victor and Laurel's article on Predator-Prey Relations, my mind exploded with visuals: foxes hiding in the bushes waiting to pounce, predictive and instinctual reactions to events, finding myself trapped in currency positions, panic driven searches for exit strategies. I realized that I am the prey. I am the new blood that greases the gears. I am the greedy trader who walks into the trap set by smarter, quicker and more thoroughly financed predators. As with much of the information gleaned from Daily Speculations, I found corollaries not just in the markets but also to life.
But wait, I've been here before. Where have I seen these deceptive techniques in use? Spy fiction. Yes, I have read all the Greene's, the Amblers', the LeCarre's, the Clancy's, the Forsyth's, the Flemming's, the Weisman's, the MacLean's, the Harris', the Buckley Jr.'s and a lot of the Ludlum's. The spy, leaving a trail, using cut outs, drops, proprietary tools and the most diabolically elaborate set ups imaginable. Institutionalized deception, deception as a way of life, and tradecraft so efficient as to make the prey oblivious to the fact that they have even been caught.
War is serious business whether or not it be cold, which brings me to the non-fiction. The Secret History of the KGB, the History of the Mossad, the development of the Office of Strategic Services, The Wall Jumper, the techniques of SMERSH, Stalinism, Churchill's autobiographical books and one of the greatest historical accounts on the subject, A Man Called Intrepid by William Stevenson. Control will leave no stone unturned to reveal facts. Control will sacrifice lives to perpetrate false information.
Why should the markets be any different? It's scary to think that once I feel like I'm playing the charts like a marionette, it is I whose strings are being pulled. I am a novice speculator, but my eyes are widening. If only I had Victor's booklist before I read all those novels. All is not lost however because I am learning to tie strings from my life experience to the experience of the markets.
