Here you go mate-- tried and true (just made it up 5mins ago)


% = (AvgWin * Win%) / ((AvgWin * Win%)+(AvgLoss * loss%))


Basically you are dividing the avg win expectancy into the total expectancy

So if your win expectancy is $100 and your expectancy is $100  your total  is expectancy (win+loss) is $200, it will return 100/200 = 0.5 (break even)


If your win expectancy is $200 and your loss expectancy is $50 your total will be $250. so 200/250 = 80% (positive expectancy as is > 50%)


there you go
