Mid period (14) — a balance of sensitivity and steadiness.
What it does
Measures volatility as the average true range over period bars, in price terms.
What happens
Computed from OHLC internally (no source input). Emits after warmup; the value is in the instrument's price units, not a percentage.
When to use
Volatility-scaled stops and targets (e.g. a 2×ATR stop) and position sizing.
Gotchas
- ATR is in price units, not percent — don't compare it across instruments directly.
- It has no source input; it always reads the candle's OHLC.
