# Volume shockers — NSE scan

> Twice the ten-day average volume with a move of more than 5% — the day something happened.

```sift
where volume > 2x avg(volume, 10) and change > 5
```

The most-cloned scan on Chartink, and worth having for the same reason: it is the shortest path to the day's genuinely unusual names. A shorter ten-day volume baseline than the standard twenty makes it react faster, which is the point — this is a scan for finding out what happened today, not for timing an entry.
