The first point: first, determine whether to exercise, and then the option buyer will declare the right of exchange before 3: 30 pm on the exercise date, and the seller will know the distribution result that night.

The second point: then be prepared to exercise your rights, and both buyers and sellers should be prepared for the transaction. The buyer who subscribes for the option should prepare the money on the exercise day, and the seller should prepare the coupon on the next trading day according to the distribution result. Put options are the opposite. The buyer prepares the securities on the exercise date, and the seller prepares the funds on the next trading day according to the assignment result.
