ES Gap Fill Probability

How often ES (S&P 500 futures) fills its overnight gap during the regular session.

What this number means

This is a base rate — how often a gap returns to the prior close at some point during the session. It is not a trade win rate.A mechanical "fade the gap" trade with a real stop fills only ~56% of the cash session on our 3-year 1-min test and is roughly breakeven once a stop and fills are modeled. We publish the difference on purpose — see the methodology.

ES gap fills behave similarly to NQ but with slightly lower probability due to broader index composition. Most reliable between 10am–12pm ET.
