What is ATR?
ATR (Average True Range) measures market volatility. It calculates the average of the "true range" over a specified period: typically 14 periods. The true range is the greatest of:
- Current high minus current low
- Absolute value of current high minus previous close
- Absolute value of current low minus previous close
How traders use ATR
- Stop loss placement: set stops 1.5-2x ATR from entry to avoid getting stopped out by normal volatility
- Position sizing: use ATR to normalize position sizes across stocks with different volatilities
- Profit targets: set targets at multiples of ATR for consistent risk/reward
RiskPicks uses ATR in its calculator to suggest stop loss distances that account for a stock's natural volatility.
