I think it comes down to how many times his first target is reached, how much first target is to amount of risk times two, cause if first target only reached 50% of the time, are you profitable? Even at 60% if first target equals total risk, it is a losing system, that's why so many lose in day trading, at least one of many reasons, commissions/slippage really eat when doing more. Only those that do heavier volume can ek out enough for the extra ten percent. How many times does 2nd contract comes back to breakeven or less than first target?
"Edge" changes as one ages/education of price, what you once thought was important isn't even considered.
