How it works, step by step
- Define the market, timeframe and current context.
- Locate the evidence taught in this lesson.

Position size connects the chart to account risk
Position sizing converts the loss budget and stop distance into trade quantity. The same account risk produces a smaller quantity when the stop is wider and a larger quantity when it is narrower.
Use the instrument contract specification, tick or pip value, quote currency and leverage rules. Verify the calculator with a small order because crypto contracts, forex lots and derivatives can express quantity differently.
Never choose size first and fit the stop afterward. Round down to the venue step size, include fees, and cap combined exposure when several positions respond to the same market factor.
