What should I do if my account is unable to meet my margin requirement on the expiration date of an option contract due to exercise?

BiyaPay usually calculates the funds required for call-over options at or near the price before the close of the option contract expiration date. If it is calculated that the call-over funds in your account are insufficient, BiyaPay may forcibly liquidate your account to avoid insufficient margin after the call-over. If you expect that your account may have insufficient margin after the call-over, please position squaring or deposit in a timely manner to ensure that the account meets the relevant margin requirements. BiyaPay reserves the following rights to address account risks caused by insufficient call-over funds.

1.Option position squaring before expiration

2.Allow options to lapse

3.Allow call-over and force leveling of other positioning
