# Distribution warning — NSE scan

> Heavy volume, weak delivery, price down — the shape of a day traders' exit.

Canonical: https://patternsradar.com/screener/distribution-warning

```sift
where rel_volume > 1.8
  and delivery_pct < 42
  and change < -1.5
```

The inverse of the accumulation case, and the more urgent one if you hold the stock. Heavy volume with little of it delivered and a red close is a session that was traded rather than invested in, and it often precedes a slide nobody has announced yet.
