CBOE Futures Exchange issued “best practices” for trading privilege holders (“TPH”) and market data recipients to follow to avoid potential issues that might arise when interfacing with the exchange’s trading system and market data services. Most importantly, CBOE Futures encourages TPH to contact the Help Desk timely when there are execution discrepancies, execution and/or clearing reports in excess of original order quantity or self-trade bust reports. Block trades must be reported within 10 minutes of trade time while exchange of contract for related position transactions must be reported within 30 minutes of the trade confirmation receipt.
