These are 3 Risk Management principles distilled from William Gann's writing and public remarks. Use them as a decision checkpoint: translate each rule into a yes/no test, write what evidence would change your mind, and set a review date before you act. When a rule feels vague, open the full principle page and capture the driver you can verify (cash flows, leverage, incentives, competitive edge). This is educational, not investment advice—double-check primary sources and fit every rule to your time horizon, risk budget, and constraints.

Treat each principle as a hypothesis. Write the evidence you would need, collect it from primary sources when possible (filings, letters, transcripts), and note what would invalidate the conclusion. If you can’t define inputs and triggers, you’re not applying the rule—you’re quoting it.
Pick a cadence you can sustain (weekly or monthly) and review process signals first: whether you followed your checklist, respected your boundaries, and documented assumptions. Only then look at outcomes. The goal is fewer low-quality decisions, not perfect prediction.
