❓ 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

Pre-Crash Market Top Projection (1929)
Using Master Charts, Gann identified resistance levels in major U.S. indices before the 1929 peak, warning of unsustainable speculation near key angles and time cycles.

2
Accumulation After Great Depression Low (1932)
Gann applied Master Charts to the 1932 bottom, noting price-time balance and support zones in leading industrial stocks and the Dow after massive liquidation.
