Donchian Breakout
How it works, and when it doesn't.

A new 20-day high means price has overcome resistance. Institutions chasing performance buy the breakout, creating a self-fulfilling momentum effect.

Price 759.8 inside 55-day channel [732.7, 781.6]. No breakout. MLP=51%.

Why it works

Donchian Breakouts capture price breaking out of a recent trading range. The premise is that a new N-day high is an information event — it means the market has accepted a new higher value, and momentum will follow.

The signal logic

  1. Long when price breaks above the 20-day highest high
  2. Exit when price falls below the 10-day lowest low
  3. No shorting — cash on the sideline when not in trend

When it fails

Breakout failures in range-bound markets. Every new high gets sold immediately, creating a string of whipsaw losses.
