RE: [amibroker] What metrics do you use for comparing systems ?

My favorite subject/issue--performance measurement. The most preferred benchmark by which investment and/or trading results are measured is the Sharpe ratio. However, imo there's a valid modification one should make to this measure. The Sharpe ratio assumes the risk-free rate is the interest rate of 90 day Government paper. That's unreasonable as there are plenty of alternatives that aren't classified as junk paper--270 day BBB+ Corporate notes, for example. Even GM short-term paper is still pretty much risk-free!
 
Therefore, a modified Sharpe ratio (MSR) would be: annualized daily average return less the Corporate short-term interest rate, divided by the standard deviation of the annualized daily average return, is 'my' benchmark for investment and/or trading. When calculations are annualized short-term or long-term isn't too relevant.
 
If your trading systems can't exceed 1.5 MSR--the higher the number the better the performance--it's back to the drawing board. fwiw, very few mutual funds exceed 1.0 MSR :). Very good hedge managers obtain 2.0+ MSR.
