Volatility and ATR-based stops
- How volatility changes from market to market and day to day
- How to set stops with ATR
- How ATR stops and position sizing work together
One stop size doesn't fit all
A 20-pip stop may be generous on EURUSD on a quiet day and far too tight on gold or GBPJPY. Volatility (how much a market typically moves) should shape your stop, not a favourite number.
ATR: average true range
ATR(14) is the average size of the last 14 candles, including gaps. If EURUSD's H1 ATR is 12 pips, a typical hour moves about 12 pips. If gold's H1 ATR is $8, a typical hour moves $8 (80 pips by the usual convention).
Setting stops with ATR
- Place the stop beyond the swing or level, plus a buffer of about 0.5–1 × ATR, so normal noise doesn't hit it.
- Or use a stop of 1.5–2 × ATR from entry for strategies without a clear level.
- Check the ATR of the timeframe you're trading on.
Wider stop = smaller lot
When volatility rises, stops get wider. To keep the same money at risk, the lot size must shrink. That's the formula from lesson "Risk per trade": lot size = money at risk ÷ (stop in pips × pip value). Volatile market, same 1% risk, smaller position.

Volatility changes
Volatility rises around news, at session opens and in market stress; it falls in holidays and the Asian session. Re-check ATR rather than assuming yesterday's stop fits today.
- Using the same pip stop on every market.
- Widening the stop without reducing the lot size.
- Using a daily ATR to set an M15 stop.

- Wider stops mean smaller lots for the same risk.
