When is the call-over time for options?

Call-over at expiration: Options with call-over at expiration will generally be called-over or voided after the close of trading on the expiration date; if the expiration date is a holiday, the call-over or voidage time may change, please refer to the changes in your account. Early call-over: The right holder of the option, that is, the buyer, does not currently support early call-over of the purchased option in the BiyaPay APP; the obligor of the option, that is, the seller, may be required to call-over at any time by the right holder (buyer).
