Absolutely you have to prove you can pay back this debt. It's highly likely that the rest of this guy's portfolio is worth on the same order of magnitude, this is not a call that says "You owe us $1.2MM, pay up," this is a call that says "Liquidate $1.2MM of your uncovered positions or we'll start doing it for you."

If this was the result of options being assigned in a spread trade, OP likely has a big unhedged position now. Depending on how prices moved overnight, his portfolio might have been wiped out or he might find himself up +$100k, who knows. But ~zero chance this results in $1.2MM collected from him.

True. I just don't want to get liquidated. I believe in my positions ✊🏽
