Volatility and ATR: Measuring Market Range and Sizing Stops Around It

Volatility is range, not direction. A market can be highly volatile and going nowhere; it can also grind steadily higher on minimal volatility. Confusing the two is a standard error.

ATR as a working tool

The ATR indicator averages the true range of the last N candles. True range accounts for gaps, which makes it more honest than plain high-minus-low.

Its practical value: ATR turns the vague "the market has calmed down" into a number you can size stops and targets from.

Rough daily ATR guides

These shift over time — read ATR off your own chart rather than a table.

How to apply it

Stops. 1–1.5 ATR of your timeframe. Tighter and noise takes you out; wider and per-trade risk becomes disproportionate.

Targets. A realistic intraday target rarely exceeds one to two daily ATR. Expecting three ATR in a session is usually wishful thinking.

Size. As ATR rises your pip stop widens, so volume must come down to keep money risk constant.

That last point is the one most often skipped. A trader keeps the usual lot, the market doubles its range, and per-trade risk quietly doubles with it.
