Trading Participants have the option to request self-trades be suppressed from the clearing and settlement process to avoid clearing and settlement costs for that trade.

To be a qualifying self-trade the following conditions must all be met:

• the orders have the same Trading Participant ID (but not necessarily the same port ID)
• that participant has requested trade suppression for the market segment to which the order relates
• the orders both show the trading capacity as being "principal"
• the orders are both for the "house" account

Trading Participants must select whether trade suppression is to be activated on a market segment. When selected from a particular market segment, all qualifying self-trades for that trading participant will be suppressed. This includes trades on the displayed book, or Chi-Delta. The trading participant does not have the option to suppress trades on a trade by trade basis.
