Reverse Up-Thrust
Volume Spread Analysis glossary · Effort vs Result & Spread/Close Analysis
Definition
Also called Professional Support: a wide-spread down-bar, closing on the highs, on high (but not ultra-high) volume, occurring during a decline; the bar may gap down at the open and the following bar ideally gaps up. It is a less extreme variant of stopping volume—a mini selling climax in which professional buying enters to slow or halt the down-move. Subsequent low-volume down-bars (no selling pressure) confirm that the strength is genuine.
Reverse Up-Thrust in plain English
This is the same pattern as 'Professional Support' — just a second name for it. During a decline you get a wide down-bar that closes right on its highs on high (but not extreme) volume, sometimes gapping down at the open with the next bar gapping up. It's a 'mini selling climax': professional buyers step in to slow or halt the fall, which is why the bar recovers to close near the top. If the following bars fall only on LOW volume (no selling pressure), that confirms the buying was genuine and the strength is real.
