70% of POP is the Probability of Profit (1 cent) at expiration. Since you don't hold until expiration, that is moot. Even if your POP was 70% of gaining your 50% mark (which it most definitely is NOT) it is a poor expectancy trade. It would be 70 trades for $1.04= $72.80 30 trades for $2.08= $62.40 10 bucks over 100 hundred trades before slippage and commissions. Does that really make sense to someone?
