For example, if you submit a one-sided buy order at 5.50 for an option on TSLA, buy one at 5.50 and sell one at 5.60, your buy order may not be filled because the sell order at 5.50 is only part of a combination order; There is no liquidity in the market. (9) What should I do if my account is unable to meet the margin requirement on the expiration date of the option contract due to exercise?
