Analyzed Economic Effects
5 provisions identified: 4 benefits, 1 costs, 0 mixed.
Harmonized Trading Halt Rules
The Exchange adopted new rules that integrate definitions and concepts from the Amended CTA/CQ Plan so trading halts and resumption procedures are more harmonized across U.S. equity exchanges. This change is intended to make halt decisions and reopening processes more consistent for traders and market participants.
Operational Halts Cancel EDGA Orders
The Exchange can declare Operational Halts that apply only to EDGA; while a security is subject to an Operational Halt the Exchange will not accept orders for queuing before resumption and any open orders on the EDGA Book will be cancelled. The Exchange will resume trading when it determines trading can resume in a fair and orderly manner and will reopen the security without a queuing auction process.
SIP Halt Resumption Details
For SIP Halts, during Regular Trading Hours EDGA may resume trading after the Primary Listing Market resumes trading or sends notice; if the Primary Listing Market does not open a security within the time its rules specify after the SIP Halt Resume Time, EDGA may resume trading. Outside Regular Trading Hours EDGA may resume trading immediately after the SIP Halt Resume Time.
Fixed Start Time for Regulatory Halts
The rules say the official start time of a Regulatory Halt is the time the Primary Listing Market declares the halt, even if notice is not immediately disseminated. This gives market participants a fixed reference time for when a halt began.
No New Fees; Immediate Filing Effect
The Exchange states these rule changes involve no new fees and the filing was submitted as immediately effective upon filing on March 6, 2026. Traders and market participants can operate under the clarified rules starting March 6, 2026 without added charges.
