BiyaPay typically calculates the funds required for exercising in-the-money or near-in-the-money options intermittently before market close on the expiration date; if it is calculated that your account has insufficient funds for exercise, BiyaPay may force close positions in your account to avoid margin deficiency after exercise. If you anticipate that your account may have insufficient margin after option exercise, please close positions or deposit funds in time to ensure your account meets the relevant margin requirements. Regarding account risks caused by insufficient exercise funds, BiyaPay reserves the following rights:
1. Close positions before option expiration
2. Allow options to expire worthless
3. Allow exercise and force close other positions.
