ATR Dynamic Profit Target and Stop Loss Strategy

Strategy Logic

This strategy uses dynamic profit targets and stop losses that adjust based on current price and volatility.

The logic is:

  1. Calculate Average True Range (ATR) over a period (e.g. 20 days)

  2. In uptrend, profit target/stop is highest price minus ATR multiple

  3. In downtrend, profit target/stop is lowest price plus ATR multiple

  4. Reverse trade when price exceeds profit target/stop

  5. Trend changes when price breaches profit target/stop

  6. Adjust profit target/stop based on new trend state

The strategy leverages ATR to automatically set dynamic trailing profit targets and stops. This allows timely locking in of profits and preventing excessive losses.

Advantages

  • ATR automatically calculates profit/stop levels

  • Dynamic adjustment trails price in real-time

  • Timely profit taking and stopping controls risk

Risks

  • ATR parameters require optimization

  • Stops too close risks being stopped out

  • Need to monitor real-time ATR changes

Summary

This strategy uses ATR to dynamically set profit/stop levels for automatic trailing. ATR tuning can improve stop performance. But over-tight stops require caution.
