Trading can be carried out on the last trading day of options. The last trading day of options is also called doomsday trading. Generally, there will be relatively large market trends.

On the expiration date of the option, you need to pay attention to the following matters

Exercise: On the expiration date of the option, the option holder who holds the right can choose to exercise the option contract. For American options, the holder can exercise the option before any trading session; while European options can usually only be exercised during a specific period on the expiration date.

Seller obligations: For option sellers, you may need to pay attention to the possibility of exercise on the expiration date. If the option contract has not been exercised on the expiration date of the option, the seller still needs to bear the risk of the unexercised contract, so the risk needs to be carefully managed before the expiration date.
