❓ Why It Matters
Without process, there is no reliable feedback loop. Structured execution and review improve decision quality over time.
🎯 How to Practice
Run a decision loop of research, thesis, execution, and post-mortem; document assumptions and update playbooks with evidence, not hindsight bias.
⚠️ Common Pitfalls
Having opinions without execution criteria
Reviewing outcomes but not decisions
Abandoning rules during volatility spikes
📚 Case Studies
1
Crash of 1983—87 Bull Market Reversal (1987)
An investor rides the strong 1980s bull market, but unlike peers, applies Gann’s rules: pyramids cautiously, sets stops, and watches time and price cycles.
✨ Outcome：Capital mostly preserved in October 1987 crash; limited drawdowns and quick recovery enabled by disciplined exits.
2
Pre-Crash Distribution Pattern (1929)
Gann observes repeated geometric and cyclical signals of exhaustion in leading industrials before the 1929 crash, aligning with his natural law timing cycles and price angles.
✨ Outcome：Reduces long exposure and initiates short positions, profiting significantly as the market collapses into 1932.
