Good sizing starts
with the stop.
Your risk budget sets the ceiling. The distance to your stop and the contract's dollar value determine how many whole contracts fit.

- Risk budget = balance × risk % ÷ 100
- Risk per contract = |entry − stop| × dollar value per point
- Contracts = risk budget ÷ risk per contract, rounded down
- Notional = contracts × entry × dollar value per point
- Reward-to-risk = |target − entry| ÷ |entry − stop|
Whole positions always round down. Notional value is market exposure, rather than the margin required. Fees, slippage and margin requirements are excluded.
A plan is only
the beginning.
Practice the entry. Follow the stop. Review the decision.
