Exclude Auction Trades from Risk Counts
If you are a Member of Cboe EDGX, you may choose to exclude auction-executed volume or executions from how the Exchange counts your activity toward risk limits. The rule names AIM, C-AIM, SAM, C-SAM, SUM, and COA auctions and lets you decide whether auction volume or executions count toward class, EFID, or EFID Group limits on both an interval and absolute (daily) basis, effective January 14, 2026.
Count Volume by Contra-Party Percentage
If you are a Member of Cboe EDGX, you may set the volume or execution count that counts toward your risk limits based on contra-party capacity, specifying a percentage up to 100%. For example, a Member could elect that only 20% of quantity from trades with Capacity "C" (Public Customer) count toward class, EFID, or EFID Group limits, on both an interval and absolute basis; this option is effective January 14, 2026.
