Turtle-Style Donchian Breakouts with ATR Risk Stops

Summary

This introductory Turtle-style system uses Donchian channels to generate trend-following entries. A break above the entry channel triggers a long position, while a break below it triggers a short position; channel breaks in the opposite direction close positions. The document describes separate entry and exit channel lengths and an ATR-based stop distance, with example settings using a 20-period entry channel, a 10-period exit channel, and a 20-period ATR. The supplied script is configured for one direction at a time and does not implement the full Turtle rules.

The backtest configuration names BTC_USDT futures and a historical period, but no returns or risk statistics are reported, so it cannot establish performance. The document notes that parameters may need to vary by instrument and timeframe, and that whipsaws, repeated stop-outs, price gaps, and trading costs can affect results. It also points out omitted features such as pyramiding and a filter governing entries after winning trades. Suggested refinements include testing parameters and adding filters for range-bound conditions.

Key ideas

• Donchian channel breakouts provide the entry and opposite-channel exit signals.
• ATR is used to scale stop distance to recent market volatility.
• The example distinguishes entry and exit channel lengths and allows long-only or short-only operation.
• The described version omits some Turtle rules, including pyramiding and a post-winning-trade entry filter.
• Whipsaws, instrument-specific settings, gaps, and transaction costs can undermine performance; no results are reported.
