Trend Indicator: Donchian Channel

Background: The Donchian Channel method, also known as the 4-week or 20-day rule, was developed by Richard Donchian, one of the pioneers in commodity trend trading with mechanical trading systems. He also developed a trading system based on 5-day (a week) and 20-day (a month) moving averages.

Trading systems today tend to become very complex by taking advantage of computer-power, but the very simple Donchian Channel method was found to be the most successful of all approaches in studies of futures trading during the 1960s through the 1980s. Traders have made many modifications of these channel breakout systems, including the well-known Turtle trading technique used by Richard Dennis.

Purpose: The basic Donchian Channel method identifies the precise points where prices break through the high or the low of the previous 20 days. Traders use these breakout areas to enter and exit long or short positions with a stop-and-reverse, always-in-the-market approach. The trades are likely to be long-term position trades and may require the use of long-term continuous charts.

Basic signals: The rules for the 4-week Donchian Channel method are very simple:

  • Go long (and cover short positions) when the price exceeds the highs of the previous four weeks (20 days).
  • Go short (and exit long positions) when the price falls below the lows of the previous four weeks.
  • Repeat as necessary.
  • Roll into the next contract, if necessary, on the last day of the month before expiration.

The chart below illustrates the basic 20-day channel method with the buy and sell points on the breakouts. However, the time frame or degree of risk from always being in a position may be greater than some traders would like.

Modifications include entering on the breakout of the 20-day high or low but then exiting on a breakout of the previous 5-day or 10-day high or low to get out of the market for a time. Then wait for a new 20-day breakout signal to re-enter the market. Or traders may take a page from other envelope strategies and decide to exit on the penetration of a moving average or some other indicator signal.

Pros/cons: The Donchian Channel method provides clear, straightforward points at which to buy and sell as a mechanical system should, and is certainly simple enough to understand. It should catch and stick with most major trending situations and, in those conditions, will produce fewer trades and lower brokerage costs.

Like most trending indicators, the Donchian Channel method will not catch market tops or bottoms, and it can be subject to significant losses from sharp price moves or from whipsaw trades in stagnant, range-trading markets. As mentioned, the entry/exit parameters can be modified to alleviate these situations, but then the choice of time periods to act on the highs or lows becomes subjective and reduces the effect of a mechanical system. In addition, rolling over into the next contract may cause problems if there is a significant difference in the pricing of the two contracts.

Visitor - Ravi Krish: Good explanation on the DC. On the above chart, on May 21, though the candle went past the lower channel, it is not a short entry. However, very similar one on Sep 17th is a short entry. How do we foresee the trend? Also, can we consider the the upper and lower channels as support and resistance and react accordingly when the price reaches these lines? For example, on May 21st it would be long entry. On around Sep 17th, it breaks the high and it didn't establish the low until Oct 8th or so. so, this would be a short entry and exit. Any thoughts?
Visitor - Paul: Very clear explanation of the Donchian strategy. I think that most articles on the subject converge towards the same conclusion, i.e. the system is profitable. How much profitable would be a useful information to add. I guess it is something I should do for myself by backtesting all currency pairs on all timeframes. Anyhow thanks for your informative article.

Visitor - Roger Felton: Excellent explanation of the Donchian Channel

Formerly Editor-in-Chief of Futures Magazine, Darrell has been writing about financial markets for more than 35 years and has become an acknowledged authority on derivative markets, technical analysis and various trading techniques.

Raised on a farm near the tiny southeastern Nebraska town of Virginia, Jobman graduated from Wartburg College in Iowa in 1963. He began his journalistic career as a sportswriter for the Waterloo (Iowa) Courier for several years before going into the Army. He served with the 82nd Airborne Division and as an infantry platoon leader with the Manchus in the 25th Infantry Division, including nine months in Vietnam in 1967-68, earning the Silver Star and Bronze Star.

After military service, Jobman returned to the Courier, where he became farm editor in early 1969. He was introduced to futures markets when he wrote a column about how speculators were ruining farm prices and was “corrected” by Merrill Oster. That led to writing assignments for Oster and then a full-time position in 1972, where Jobman participated in the founding of Professional Farmers of America and associated newsletters.

When Oster purchased Commodities Magazine in 1976, Jobman was named editor and later became editor-in-chief of Futures Magazine when the name was changed in 1983 during one of the biggest growth periods for new markets and new trading instruments in futures history. He was an editor at Futures until 1993, when he left to become an independent writer/consultant.

Since 1993, he has written, collaborated, edited or otherwise participated in the publication of about a dozen books on trading, including The Handbook on Technical Analysis. He has also written or edited articles for several publications and brokerage firms as well as trading courses and educational materials for Chicago Mercantile Exchange and Chicago Board of Trade. He also served as editorial director of CME Magazine.

Jobman and his wife, Lynda, live in Wisconsin, and spend a lot of time visiting with a daughter and three grandchildren also in Wisconsin, and a son and granddaughter in Florida.
