# ATR stop and target

The stop sits `stop_mult` times the average true range from the entry. The target is `target_r` times the distance to the stop, so a target of 2 risks one to make two.

> **Trap.** A stop measured in a fixed number of points is too tight in a quiet market and too wide in a busy one. Measure it from the market's own range.
