SEC grants IEX immediate effectiveness for rule extending trading alert deadline

The Securities and Exchange Commission has made effective, without delay, Investors Exchange LLC's (IEX) proposed rule change that extends the implementation timeframe for trading pegged orders during pre-market and post-market sessions. The filing, designated non-controversial, was submitted on September 2, 2026 and the Commission waived the standard 30-day operative delay, allowing the rule to become operative upon filing.

Under the original filing (SR-IEX-2026-19), IEX was required to issue a Trading Alert announcing the implementation date no later than October 8, 2026, with at least ten days' notice to market participants. IEX now seeks to push that Trading Alert deadline 60 days forward to December 7, 2026, while maintaining the ten-day pre-implementation notice.

The exchange states the extension is needed to complete all steps in its standard deployment schedule and to issue the Trading Alert in a thorough, risk-averse manner. No other terms of the original rule change are being altered, and IEX does not anticipate any burden on competition.

The Commission may, within 60 days of the filing, temporarily suspend the rule change if it deems such action necessary for the public interest or investor protection. Interested parties may submit comments referencing file number SR-IEX-2026-30 via the SEC's electronic comment form or by paper to the Commission's Secretary.
