How to use Volume & Sigma Spikes Guide
1
Read sigma and volume together
A large price anomaly with weak volume can mean something very different from a price-and-volume spike appearing together.
2
Start with the shortest view, then confirm on longer windows
Daily helps you catch the move early, but weekly and monthly tell you whether it is developing into a stronger story.
3
Promote only context-rich signals
Signals near support, breakout zones, or key news moments are usually more actionable than random outliers.
4
Use the page as a discovery layer
The best workflow is to take a flagged name into chart review, sector context, and a more specialized screener next.
Sigma spikes show abnormal price movement relative to recent volatility.
Volume spikes show abnormal participation and can validate or challenge the price move.
The strongest candidates often show repeated abnormal behavior across more than one window.
Common mistakes to avoid
Treating every anomaly as bullish.
Ignoring where the signal appeared on the chart.
Skipping follow-through review after the first spike.
