Volume spike — crypto futures scanner
Something happened: the last closed bar traded at least 3× its 20-bar average volume.
The exact conditions
No black boxes — this is precisely what fires, computed on closed bars from public candles, in your browser.
- Volume on the last closed bar ≥ 3× its 20-bar simple average
How to read a hit
Volume says attention, not direction — the candle's own color gives the first hint. Open the report's depth and flow panels to see who was doing the buying or selling.
Every hit links straight into its Signal Report — levels, regime, expected move, funding, depth — so the scanner finds candidates and the report does the judging.
