1 The Story

The man who made trend following a system

Richard Davoud Donchian (1905–1993) was an American commodities trader and the pioneer of the managed-futures industry. He began trading in the 1930s, served as a cryptanalyst in World War II, and in 1949 launched Futures, Inc. — one of the first publicly managed futures funds.1

He developed the Donchian channel breakout system and a set of trend-following 'guides,' aiming, in his own words, not to forecast prices but to provide a simple way to get aboard important trends.1

2 The Big Idea

Don't predict — follow

Catch the big trends with simple rules, and cut the losers fast.

Donchian's insight was humility: you can't reliably forecast prices, but you can build mechanical rules that get you aboard a real trend and out of a failing one. You don't need to be right often — you need to ride the winners and keep the losers small.1

3 The Method

Channels, breakouts, and rules

The Donchian channel

Track the highest high and lowest low of the last N periods. A push beyond that channel signals a new trend worth following.

The 4-week rule

A mechanical classic: buy on a new 4-week high, sell or reverse on a new 4-week low. Simple, robust, hard to argue with.

The 5/20 system

A moving-average crossover (5-day vs. 20-day) — one of the first systematic trend filters.

Cut losses, let winners run

The discipline that makes trend following actually work: small, fast losses; big, patient winners.

Donchian channel: buy a breakout to a new N-period high N-period high (upper channel) N-period low (stop) breakout above the channel → buy & ride the trend
The Donchian channel marks the recent high and low; a breakout above the upper channel is a mechanical signal to join the trend, with the lower channel as the exit.2

4 Try It Today

Test the idea for yourself

A no-risk exercise

On a trending chart, draw the highest high and lowest low of the last 20 bars — that's a Donchian channel. Mark where price broke above the upper line, and imagine an exit if it later broke the lower line. Notice how a simple, mechanical rule would have kept you aboard the trend without a single forecast.
