1) What happens to first and runner-up profit Factor? How can it be possible Zero?

My next question is, why is Pass 3 Profit Factor so huge? The article wrote ProfitFactor = GrossProfit / GrossLoss. To me, this is really important result. 193 mean for every $193 bucks gained, it lost ONLY $1 buck. So the silly question is: Is all this for real?

I assume that for passes 5, 4 and 6 there were no losses so the Gross Loss is zero, rather than showing a Divide by Zero error ;-) a result of 0.00 is shown. For run 3 there was a Gross Loss but it was very small so GrossProfit / GrossLoss gives a high figure.

The numbers I look at are Profit, Total Trades (I want a reasonable sample set) and Drawdown %age
