Find stocks with 3x+ their normal volume. Unusual volume scanner detects institutional buying and selling activity across 5,000+ stocks.
Massive absolute volume spikes are one of the cleanest tells in the market. When a stock that normally trades quietly suddenly explodes to 3x, 5x, or 10x its 50-day average volume, somebody big is acting — institutional accumulation, news catalysts, earnings reactions, or distribution. This day-trading scanner uses a statistical z-score on top of the raw volume ratio to flag spikes that are not just high, but genuinely abnormal versus that name's own history. Each spike is then classified as Accumulation (price closed up) or Distribution (price closed down) so you instantly know which side is in control.
For unusual volume setups, an A+ grade means today's volume is 8x+ the 50-day average with a z-score above 3 standard deviations and absolute volume above 10M shares. A grades require 5x+ ratio with statistical extremity. B+ requires 4x+. B meets the 3x minimum trigger. This is not a prediction of future price movement — it is a way to prioritize which charts deserve your attention first.
