For example....

in this EA
http://www.forex-tsd.com/49739-post90.html

the third position in the series of five has the following win/loss report

winners 1273
losers 184

therefore it's win/loss ratio is
the number of winners/total trades or...

1273/1457=0.873713109=87%

can any other EA beat that I wonder?

To figure this out I isolated each position the EA took based on it's lot size. I could do that because this EA doubles the lot size for each trade in the series of trades it executes when it trades. I copied the strategy test results into excel and simply sorted for each trade of the same lot size and then counted how many won and how many lost for each of the five (when maxtrades=5) that it executes.

87% is pretty good I think. but I wonder if there are any better?

Anyone know of a better win/loss ratio?
