LOL I don't know, sorry... I just used some js formula in some site that did the math.

I will find it as soon as I can!

ROR=1/(1 + %Exp)^(Ic/Ir)

Where
%Exp is the Expectancy as percentage.
Ic is Initial Capital.
Ir is Amount at Risk per each trade.

I would define Ic/Ir as how many consecutive losses a trader can afford before going broke, if I risk 1% per trade, then Ic/Ir= 100

My prob. of losing my stake is 1.63^-53... so practically 0, I think the formula is too optimistic, I would like some people's opinion!

Expectancy must be positive, there are different formulas, I think all of them reflect similar results.

Then that would be risk of drawdown (50%)?

Consecutive Losing trades are based on average loss?
