Count Trades by Contra‑Party Weight
If you are an Entering Firm (an OTP Holder or OTP Firm), you may now tell the Exchange to count trades toward your Activity‑Based Risk limits using a contra‑party weighting of up to 200%. This applies to the Transaction, Volume, and Percentage activity limits; for example, you could choose to count only 50% of the quantity on each trade with a Customer toward your limits.
Market Makers Must Use Activity Controls
Market Makers are required to apply one Activity‑Based Risk Control to all of their orders and quotes on the Exchange. As Market Makers, they may now also specify contra‑party weights (up to 200%) when setting those controls.
Optional Feature Available to All Firms
The contra‑party weighting enhancement is optional and is available to all Entering Firms (including Market Makers) to use at their discretion. The Exchange states the enhancement applies uniformly to any Entering Firm that chooses to utilize it.
Rule Change Effective Immediately
The Exchange filed the change on May 19, 2026 and the proposed rule change became effective upon filing under the fast‑track rule (Rule 19b‑4(f)(6)). Entering Firms can begin using the new contra‑party weighting option immediately, though the SEC may summarily suspend the change within 60 days of the filing.
