Although the option buyer has the right to perform or not to perform, it must make a statement before the expiration date of the option. The buyer's non-performance statement has no specific provisions and is limited to the expiration date. Generally, the reporting date of the buyer's performance is predetermined in option contracts, which is called the notification date or the reporting date. That is, when the option buyer requests to perform the option contracts, it must notify the seller before a predetermined date (including that date) before the expiration date, so that the seller can prepare for the performance. If the buyer fails to issue a performance statement before the notification date, it shall be deemed as a waiver of the grant right. When to set the notice date is stipulated in the option contracts, which generally depends on the validity period of the option, and some are 5 days, generally within L- 12 days. The option seller has the obligation and responsibility to accept the buyer's performance requirements. Therefore, once the buyer puts forward the performance requirements, the seller must immediately prepare for the performance and complete the delivery procedures of the relevant futures before the maturity date. The date when the buyer and the seller perform the procedures for futures delivery related to options is called the "performance date". Strictly speaking, the performance date and the due date are different. The former refers to the date when the option holder actually fulfills the right to buy a call option or a put option. The expiration date refers to the last date when the option can be exercised. According to this description, you cannot perform the contract. If the buyer gives up, the seller will automatically fail to perform the contract.
