As part of an amusing, frustrating, wretched but ultimately uplifting and loss minimising part of my daily routine, I categorize mistakes made, differences observed and yes, things that were done successfully in a timely manner.

The hope is that there are some pedagogical benefits to be had from said classifications. What follows is a hard list (no wisdom or homey style nuggets).

It is regrettable that I do not have much perspective on broader aspects of life outside markets that might allow something approaching the towering lists of a Tom Wiswell. But it is what it is and anyway, I have Messrs. Jovanovich, Watson, Niederhoffer & The Poltergeist that provide one with regular cerebral sustenance.

I entitled this post the things 'we' do wrong. The list is mainly me, but I have had the privilege of observing the best and brightest so there are are few others added. All of their problems are subsidiary to mine:

1. Not enough focus on the stock market. I have missed substantial turns in stocks bearish and bullish because one imagined a speculation in Gold, for example, to have been more important.

2. Ignorance of a certain portion of the trading day (heaven forbid I might rest a while). In my defense, this has been fully rectified.

3. Not focusing enough on trade size. I keep an approximately equal size per speculation as I take some 2500-3000 odd trades a year. My view has been if one trade stands that far ahead of the others in terms of expected return, then why would you bother with the 'sub optimal' trades? Thus the constant position size.

4. Ignoring holding period (I am fortunate to say that this is not a point of worry personally).

5. Never adding to positions.

6. A dislike of hard core programming. I much prefer a simple interface through which questions can be asked. It is notable that the only products in this category that are any good are not available for purchase. It is only in recent times that programming/ hacking skill was valued above picking direction accurately. A reckoning approaches on this but I will not discuss it here.

7. I trade too many markets. My universe has 23 macro instruments in it. 3-5 would suffice.

8. I have never found anything REPEATABLE with a holding period more than a couple of days that satisfies me or any of my backers (who would never allow a 10% + drawdown).

9. This one is a bit controversial. I always assume the other market participants are 'better' than me. That their strategies are better in some way. This has stopped me going for the kill in a few very notable instances.

10. I don't have risk on in the moments before scheduled economic announcements or planned flexionic commentary. This has cost me but has allowed a very very low volatility relative to return down the years.

Good list. Particularly the conjunction of size, time horizon, and to add a few of my own - reaction to a destabilizing price shock, endowment effect, prospect-type behavior, distractions such as an in-law asking to participate with you for the day, rationalizing excess conservatism when aggression is warranted which leads to the avoidance of big scores, among other things.

Chutzpah built up over an outsized good run (frequency of wins or profit generation) leads to stepping on a landmine you could have avoided if leverage was kept in check.

I've accepted the fact that I will feel like an idiot on a day to day basis. The upside of this is that when I calculate a 6 year compound return as I just did last week, I'm stunned as to how it occurred. How can one climb a mountain (in my case a not so big one) while always feeling one is falling and failing.

It is always good for a speculator to be humble. Also I think to follow Irving Redel's rule whenever people ask him how he's doing in market: "Fair".
