This report "Trading With SVMs: Performance" sounds very interesting. The result on trading the S&P500 (without leverage, I think) since 1952 is 32.59% of annualized return while during the same period Buy&Hold is only 15.14%.

Here is Wikipedia's article on SVMs.

I wonder if anyone has used SVMs in real trading. Could you kindly share any experience about it?

One of my very rare strengths counterbalanced by many much more glaring weaknesses is that I can usually look at any paper in statistical finance and find its weaknesses in 30 seconds or less. I looked at support vector machines in that context and could not figure out why it should do better than discriminant analysis or similarity analysis. I was turned off by the statement that armi garch results using the last 5 changes gave similar alluring results, as I don't believe they will work unless they are retrofitted during particular periods. The non-linear features that SVM tries to capture would not be predictable or repeatable I would think nor would it in any case be immune to ever changing cycles. I will look at this much more carefully with the doc before I can render a totally worthless opinion on this.
