Premarket Scan
Prototype report: this page uses the completed-premarket simulation performed after the scheduled 08:30 ET window. NATL qualified later and was not part of the original 08:45 scanner run. Future reports will use the exact scheduled snapshots.

Regular + Post-market Scan
Complete scan: all 2,967 eligible symbols returned quotes. The date-range history endpoint reached its monthly symbol quota, so the scanner used Longbridge's last-1,000-bars fallback and validated all 240 completed post-market minutes for each candidate.

Average volume is the mean regular-session volume over the previous 20 completed trading days. Higher relative volume indicates stronger participation, but it does not prove that a breakout is real or durable.
