When I sell a put for a stock or ETF, the maximum margin the brokerage firm (Etrade for example) seems to be holding is 20% of the underlying plus premium.
Supposing I get assigned and don't have enough cash to purchase the underlying, what would happen?
Will the brokerage firm automatically sell the underlying immediately and/or can/should I arrange for this to be done?
Say, I sell 1 contract GLD put @ 170 strike price and the price falls to 168, but I don't have the $17,000 to buy 100 shares GLD, will I get somehow penalized for this, or would I just get $200 ($2 difference) deducted from my account to cover the immediate buy/sell?
