How to use this data

The historical columns show what happened the last N times this ticker gapped by similar size. They are population statistics — your specific setup (float, news, premarket volume) will differ. Use them as priors, not predictions.

Premarket data delayed ~15 minutes. Historical stats based on 400,000+ Trade-Ideas alerts since 2019. Past performance is not indicative of future results. Not investment advice.
