I wish I could take that type of position with only 20$....A real world example:
previously only $20 (= strike minus premium) was needed for shortselling a Put with strike=4 and Premium=3.80.
Now they say I need $400 !
This is ridiculous! B/c they now lock $400 plus the credit $380, in total $780 !!! That's sicko logic they now apply!
That trade can never lose more than "strike - premium", ie. $20, but they want a collateral that is 20 times of that (or even 39 times of that)!...
It seems to me you really want to understand the why of this issue. Why not get on the phone with your broker and keep going through their support peeps until you get someone who can answer the question to your satisfaction? Put a nail in it once and for all.
