ATR: meaning, example and why it matters

Average true range: a measure of how much a price typically moves in a period, including gaps. Wider ATR means a more volatile instrument, which is why ATR-based stop-losses sit further away for volatile stocks and closer for calm ones.

Worked example

If five days of true range are 4, 6, 5, 7 and 3 points, a simple 5-day ATR is (4 + 6 + 5 + 7 + 3) ÷ 5 = 5, so the instrument typically moves about 5 points a day. Wilder's smoothing gives slightly different values.

Why it matters

ATR expresses typical movement in price units, which is useful when deciding how far apart to place exit levels or how large a position to hold.
