IEX rule change extends implementation timeframe, becomes effective immediately
The Investors Exchange's proposed amendment to its pegged and D-Limit order rules applies to all market participants and takes effect upon filing on November 10, 2026.
On November 4, 2026 Investors Exchange LLC filed a proposed rule change under Section 19(b)(1) of the Exchange Act. The Securities and Exchange Commission designated the filing non-controversial, waived the standard 30-day operative delay, and made the proposal operative upon filing.
The proposal seeks to extend the implementation timeframe for the rule changes originally filed on July 10, 2026 (SR-IEX-2026-19). Those changes would make certain pegged order types and the Discretionary Limit (D-Limit) order type eligible for trading during the Exchange's Pre-Market and Post-Market Sessions. The original filing required a Trading Alert at least ten days in advance and within 90 days of effectiveness, which would have set a deadline of October 8, 2026. An initial extension filed on September 2, 2026 moved the deadline to December 7, 2026. IEX now proposes to extend the deadline to the end of the first quarter of 2027.
IEX will still issue a Trading Alert at least ten days before the actual implementation date, which will occur on or before the end of the first quarter of 2027. The Exchange states that no other terms of the original rule filing are being altered and that the change imposes no unnecessary burden on competition. No written comments were solicited or received.
The Commission may temporarily suspend the rule change within 60 days of filing if it deems such action necessary to protect investors or the public interest. Interested parties may submit comments on the proposal as outlined in the filing.
