When a stock freezes, we don't tell you to buy or sell. We show you, calmly and in plain English, what stocks like this have actually done before.
Honest historical context — not predictions, not advice. No buy/sell calls. Not financial advice.
The stock freezes. Your orders are locked. The Level 2 goes blank. For five minutes, nobody knows anything — but everyone is screaming. Discord lights up with “moon” or “dump” calls from people with zero track record. You're left staring at a frozen screen, making a decision based on noise instead of data.
When a stock reopens sharply higher after a limit-up halt (a 10%+ gap), it has historically closed lower by the end of the day about 65% of the time (n≈389 NASDAQ halts). The bigger the pop, the more often it gives some back.
But this is history, not a forecast — roughly 1 in 3 still closed higher, and a few ran hard. No one can tell which one you're looking at in advance.
LULD halts detected and AI-scored as they happen. Make your call before the reopen and see how you stack up.
Every halt opens a prediction window. Pick UP or DOWN. Add a price guess if you want. We resolve at the moment of reopen — not 5 minutes later, not at close. The same number you predicted is the number that scores.

Halt alerts tell you a halt happened. We tell you what's likely to happen next — direction, cascade probability, and (Pro) price range — calibrated against 71,000+ historical halts.
Yes, forever. Make as many predictions as you want. The leaderboard ranks users by accuracy across at least 10 calls.
