Similar to moving average–based systems, a breakout trading system can take many forms. To test a different approach, you can define a breakout system as follows:
Buying at tomorrow’s opening price when today’s closing price is above the highest high price that occurred during the last 20 days
Selling at tomorrow’s opening price when today’s closing price is below the lowest low that occurred over the last 20 days
These trading rules are loosely based on the rules for Donchian channels (sometimes called price channels), which comprise a breakout system developed by Richard Donchian in the 1950s.
