Position sizing, drawdown math, R-multiples, expectancy and the rules that keep accounts alive.
The single most important number in trading isn't your win rate — it's how much you risk per trade.
Stop thinking in pips and dollars. Thinking in R turns every trade into a comparable, repeatable unit.
A stop placed too tight gets clipped by noise. A stop placed too wide destroys your risk-reward. Here's how to place it right.
Exiting is harder than entering. Fixed targets, trailing stops and scaling out each solve different problems.
Losing 20% requires a 25% gain to recover. Losing 50% requires 100%. Drawdown math is brutally asymmetric.
