Hi
The value of an american style option has to be positive.
I would like to explain a situation that has happened a few times.
In a multyleg strategy my sold put become ITM and I am early assigned, somy position is bought in stocks. Then the margin requirement is higher than my available cash so I have to remake the position.So I sell stocks and sell another otm put and my position remains as the begining. To do that I have 10 minuts, from 9.30 to 9.40 EST ,
because if not the broker will…
