Position size calculator

Pick an instrument and a side: the entry starts at the live market price and the stop at a volatility distance, and you see how many lots that stop allows for your balance and risk. Change any box. The size is floored to the broker’s lot step, never rounded up past your risk.

About this tool

The size comes from the broker’s contract size and profit currency, with a live exchange rate to convert to your account currency. It is the same calculator as in our trader tools, tested there.

The starting stop is 1.5 × the average true range (ATR 14) of hourly bars away from entry: a measure of the instrument’s normal movement, not a recommendation of where to place a stop.
