Donchian Channel Midline Trend Signals and Exits

Summary

This note describes a trend-following system built from a 20-period Donchian channel. It calculates the highest and lowest closing prices over the lookback, then uses their midpoint as a reference line. A close above that midpoint signals a long position, while a close below it signals a short position. The described exits differ by side: a long closes below the channel low, and a short closes above the midpoint.

The document provides strategy rules and a BTC/USDT futures backtest configuration covering roughly one month on four-hour bars, but it reports no performance results. Its discussion identifies possible frequent reversals, transaction costs, slippage, poor parameter choices, and failed late-trend breaks. It proposes testing across market conditions and adding filters, though no evidence establishes that these changes improve results. There is also a mismatch between the prose, which refers to price breaking the channel, and the entry rules, which use the midpoint; the source calculates channel bounds from prior closes.

Key ideas

• The system uses a 20-period highest and lowest close to define Donchian channel boundaries.
• The midpoint of the channel determines whether the strategy enters long or short.
• Long positions exit below the lower channel boundary, while shorts exit above the midpoint.
• The published backtest settings specify BTC/USDT futures on four-hour bars but include no reported results.
• Frequent reversals, slippage, and failed breakouts are identified as potential risks.
