Key Takeaways
- The Average True Range (ATR) measures volatility across financial assets, including cryptocurrencies.
- Crypto traders use ATR to gauge token volatility by calculating the average distance between highs and lows.
- Helps identify optimal entry/exit points and set Stop-Loss orders.
- Limitations: Only reflects volatility, not market direction, and lacks standalone price meaning.
- Developed by John Welles Wilder, Jr. in the 1970s (also creator of RSI).
Calculating the Average True Range (ATR)
ATR is auto-calculated by trading platforms like TabTrader but understanding its components is crucial:
True Range (TR) is derived from:
- Today’s high — today’s low.
- Today’s high — yesterday’s close.
- Yesterday’s close — today’s low.
- TR = max[(high - low), |high - previous close|, |low - previous close|].
- ATR is the smoothed average of TR over a period (typically 14 candles).

How to Use ATR in Trading
Applications:
- Volatility Assessment: Rising ATR = increasing volatility; falling ATR = declining volatility.
- Stop-Loss Placement: Use ATR to set dynamic Stop-Loss levels (e.g., 1.5x ATR below entry).
- Trend Confirmation: High ATR values often accompany strong trends.
Example (BTC/USD Chart):
- A spike in ATR after a large downward candle reflects heightened volatility.
- ATR declines as price stabilizes, signaling reduced volatility.
Limitations of ATR
- No Directional Insight: ATR shows movement magnitude, not trend direction.
- False Signals During Consolidation: Expanding ATR in corrections may mislead traders.
- Context-Dependent: Single ATR values require historical price context for meaningful analysis.
Pro Tip: Pair ATR with directional indicators (e.g., RSI, Parabolic SAR) for robust signals.
Complementary Indicators for ATR
1. Parabolic SAR
- Dots indicate potential reversals and Stop-Loss levels.
- Combines well with ATR to filter noise.
2. Stochastic Oscillator
- Identifies overbought/oversold conditions.
- Validates ATR signals during volatile swings.
3. Relative Strength Index (RSI)
- Wilder’s RSI adds trend direction context.
- Midline (50) crosses can confirm ATR-based entries/exits.
FAQ
Q: What does ATR measure?
A: ATR quantifies volatility by averaging price ranges over a set period (default: 14 candles).
Q: What’s the best ATR setting for crypto?
A: 14-period ATR is standard. Adjust shorter for sensitivity or longer for smoother data.
Q: How reliable is ATR alone?
A: Always pair ATR with directional indicators (e.g., RSI) to avoid false signals.
Q: Can ATR predict price reversals?
A: No—it only measures volatility. Use with trend-confirmation tools for reversal analysis.
The Bottom Line
ATR is a powerful tool for volatility measurement and risk management, but its simplicity demands integration with other indicators. By combining ATR with tools like Parabolic SAR or RSI, traders can refine strategies and mitigate crypto market noise.
