Raw volume vs relative volume
Bitcoin trades billions a day; a small-cap perpetual trades a few million. A raw volume filter only ever returns the biggest coins. Relative volume (RVOL) compares a candle’s volume with that coin’s own recent average, so “RVOL > 3” means “three times busier than usual” on any coin, large or small.

Frequently asked questions
What is a good relative volume for crypto?
Above 2 is notable, above 3–5 is unusual. Very high readings on a single candle often mark news or liquidations, so check whether price held the move before acting.
Can I scan volume spikes for free?
Yes. Volume and Average Volume are free, so “Volume > Average Volume(20) × 3” works on the free plan on 15m and 1h. Relative Volume, CVD and alerts are Premium.
Which exchanges are covered?
About 700 Binance USDT-M perpetuals and 200+ Delta Exchange India perpetuals. CVD is Binance-only because Delta does not publish taker-side volume.
