PMCC is better than I thought

 I thought that my PMCC positions are not very good

then I realized, the long call profit is better than the short call

lets say ARKK price went from 95-103, which is $8

the profit will be $8*0.8 delta = 6.4*100 = $640 profit

then my short call went from $97 to $103

which is a loss of $6*0.2 delta * 100 = $120 loss

so overall, I still profit by $520

I just have to keep rolling to avoid the loss on the short call.
