I sold a strangle in FXI today for a 1.04 credit with 45 Dte. I will close it for 50% profit, or a loss of 2x the initial credit received, or after 22 days - whichever comes first.
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?
