Silexx API Replaces Flat Fee With Tiered Pricing
Cboe Exchange proposes to replace the existing flat $200 monthly fee for the Silexx application programming interface (API) with a three-tier usage-based pricing structure ranging from $299 to $999 per login ID per month. The proposed tiers include different rate limits and daily call caps, with overage fees of $0.01 per call for Tier 1 and Tier 2 users exceeding their daily caps. The proposal is effective March 2, 2026, and all login IDs will default to Tier 1 unless users elect otherwise.
Trading Permit Holder Statutory Disqualification Procedures Amendment to Exchange Rule 3.13
Cboe Exchange proposes to amend Exchange Rule 3.13 regarding statutory disqualification procedures for Trading Permit Holders (TPHs) to conform with FINRA Rule Series 9520 and industry standards. The proposal addresses inconsistent outcomes when FINRA processes SD applications on behalf of the Exchange, as the Exchange's current rules require 19h-1 Notices in certain circumstances where FINRA would not. The amendment would incorporate a new Statutory Disqualification Circular outlining eligibility procedures and rely on FINRA's 2009 No-Action Letter for interpretive guidance.
