Average True Range (ATR) – What It Is & How to Trade with It

What is the Average True Range (ATR)?

The Average True Range (ATR) is a technical indicator developed by J. Welles Wilder to measure market volatility by calculating the average range between high and low prices over a given period. ATR does not indicate trend direction but helps traders understand how much price moves on average.

The ATR formula is:
ATR = SMA (True Range, n-periods)

Where:

• True Range (TR) = Max[(High – Low), Abs(High – Previous Close), Abs(Low – Previous Close)]
• SMA = Simple Moving Average over a selected period (default is 14).

Key Features of ATR

• Measures market volatility instead of trend direction.
• Helps in setting stop-loss and take-profit levels.
• Works well in combination with trend-following strategies.

How to Use ATR in Forex Trading

1. ATR for Stop-Loss Placement

ATR helps traders determine optimal stop-loss levels based on market volatility:

• Volatile Market: Use a wider stop-loss (e.g., 2× ATR).
• Low Volatility Market: Use a tighter stop-loss (e.g., 1× ATR).

Example: If ATR = 50 pips, a trader may set a stop-loss 50 to 100 pips away from the entry price.

2. ATR Breakout Strategy

Higher ATR values indicate strong breakouts, while lower ATR values suggest consolidation:

• Buy when: ATR is rising, and price breaks above resistance.
• Sell when: ATR is rising, and price breaks below support.

3. ATR Trend Confirmation

ATR can help confirm trend strength:

• Increasing ATR: Market is trending with strong momentum.
• Decreasing ATR: Market is consolidating or losing momentum.

4. ATR with Moving Averages

Pairing ATR with a moving average (e.g., 50 EMA) helps manage trades more effectively:

• Buy when: ATR is rising & price is above the 50 EMA.
• Sell when: ATR is rising & price is below the 50 EMA.
