Nasdaq Temporarily Changes STGY Router Behavior for Locked and Crossed Quotes

Nasdaq issued an Equity Trader Alert on June 8 saying it will temporarily modify a specific order-routing parameter for the STGY strategy. The change applies from Wednesday, June 10, 2026 through Monday, June 15, 2026, and covers securities in the S partition on Nasdaq, Nasdaq Texas and Nasdaq PSX.

Under the temporary setting, STGY will not reroute when an away market is showing a locked or crossed quote. Nasdaq said the purpose is to help limit orders maintain queue priority. Members can continue routing orders as usual and Nasdaq said no action is required.

The update is narrow, but it matters because smart-order-routing behavior can affect where a limit order rests, whether it keeps its place in a queue and how it responds to fragmented market data conditions. For traders using broker routing logic tied to Nasdaq destinations, the practical impact is that the same order strategy may be less likely to move away from its resting venue during the temporary window.

Why it matters

Queue priority is a real execution variable for limit-order traders. A routing adjustment designed to avoid unnecessary rerouting can help preserve order position, especially in names where spreads, displayed depth and quote stability matter.

What to watch next

Watch whether Nasdaq extends, revises or ends the temporary STGY setting after June 15. Traders should also monitor execution quality reports for S-partition securities during the window.
