How to read the filters

RVOL 1.8 means today's volume is at least 1.8x the 20-day average volume. Z-score 2.0 means the move is at least two standard deviations above the stock's own recent volume behavior. Higher thresholds give fewer but cleaner anomalies.

What the scores mean

The anomaly score is a blended 0-100 reading built from relative volume, volume Z-score, and price impact. A higher score means the turnover spike is both larger than normal and more likely to matter for follow-through. Breakout and absorption tags often deserve faster review than low-conviction noise.

Volume anomalies guide for PSX traders

What does RVOL 1.8 mean?

It means the stock is trading at least 1.8 times its normal 20-day average volume. That is a quick way to separate routine turnover from sessions where participation is genuinely expanding.

Why use both RVOL and Z-score?

RVOL tells you how much larger the session is versus the recent average. Z-score tells you how unusual that change is relative to the stock's own volatility in volume. Using both reduces false positives.
