Quote from blackjack007:
you're BSing. If an option has a $2000 margin requirement and your account has $1600, you can't sell the option. Period. no broker wll let you do that.
if your account has $2001, you can sell the option but the $400 premium is not available to write additional options. That's because your account still has a value of $2001: you would have $2401 in cash but the value of the option is ($400) because it's sold short.
i find it incredible that you've ever written an option before if you don't know something as basic as this.
This person ha been doing options for 20 years ????
