What is required for two orders from the same participant to be admissible for immediate cross-matching?

For two orders from the same participant to be admissible for immediate cross-matching, it is essential that one of the orders must have been entered as a rule-consistent trade request. This requirement ensures that the orders align with trading rules and regulations, facilitating the simultaneous execution of trades in an efficient manner. Rule-consistent orders account for the necessary parameters such as price and quantity that adhere to the established trading framework.
