When taking an order, the Trading Member shall establish proper procedures to ensure that the customers' orders shall contain the following details:—
(1) whether it is a Call or Put Option;
(2) the underlying security;
(3) the Expiration Date;
(4) the Exercise Price;
(5) the number of Options to be written or purchased; and
(6) whether the transaction is an opening or closing transaction. Where the customer fails to specify whether it is an opening or closing transaction, the transaction will be deemed to be an opening transaction.
