Risk Management — Fixed Fractional, 1-2R Thinking
Risk a fixed small fraction per trade, always with a stop, and think in R multiples — not money.
The framework is fixed fractional risk: a constant small percentage of the account (commonly 0.25-1%) on every trade, with a hard stop-loss placed at the level that proves the idea wrong — never a mental one.
Denominate everything in R, the amount risked: a trade that makes twice its risk is +2R regardless of dollars, and an edge is simply a positive expectancy — (win rate x average win) minus (loss rate x average loss) — over a sample.
Position size falls out of the math: account risk divided by stop distance. As the Talaria Letters put it, arrogance in position sizing has only one price in the market; the sizing formula, not confidence, decides the trade size.
How to trade it
- Fix your per-trade risk percentage and compute size from the stop distance every single time.
- Only take setups offering at least 2R to a logical target; the minimum reward-to-risk is a filter, not a hope.
- Respect drawdown guardrails — daily loss limits and a stop-after-two-losses rule keep one bad day survivable.
Pitfalls
- Sizing up after wins or "to make it back" after losses — both break the fixed fraction that protects you.
- Moving stops away from price to avoid taking the loss — the stop is the idea’s falsification point.
