Stricter Limit Order Price Protections
24X changed the limit order price protection percentages used in the Pre-Market, Post-Market, and 24X Market Sessions to match the Core Market Session. The old percentages were 20% for securities $0.00–$25.00, 10% for $25.01–$50.00, and 6% for >$50.00; the new percentages are 10% for $0.00–$25.00, 5% for $25.01–$50.00, and 3% for >$50.00. The rule became operative upon filing on November 28, 2025, and is intended to reject limit orders priced far from the National Best Bid or Offer to provide greater protection to market participants trading on 24X.
