Survival Pillars
Long-form models and checklists. The “why” and “how” behind the cards.
Overtrading: A Systems Diagnosis (Not Motivation)
Overtrading is a control-system failure. Build gates, consequences, and decision budgets that prevent compulsive exposure.

Execution is incentives and microstructure. Learn how queues, re-quotes, last look, and order types change outcomes.
Margin & Liquidation: The Broker Rulebook in Plain English
Margin is the broker’s control system. Understand stop-out mechanics, dynamic margin, and how to avoid forced exits.
