.............................................................................................Quote from TraderZones:
It would be useful if you had a little more advanced stats. ins, Losses, average% and all of this are relatively worthless.
Newer traders focus on them, but experienced traders know they don't really tell you anything about trading.
Profit Factor, Sharpe, max drawdown and things like that are far more valuable, even just to yourself.
Here is some discussion on calculating Sharpe: http://www.elitetrader.com/vb/showthread.php?threadid=53551
Profit Factor is simply the sum of all wins divided by the sum of all losses. ($ values, not #wins or losses)
max drawdown is simply your worst % loss, peak to valley.
