Fractional units shown. Round down to the instrument's allowed lot step. This is not margin required; fees, slippage and currency conversion are excluded.

Method and assumptions

Price distance = ATR × multiplier. Long stop = entry − distance; short stop = entry + distance. Account risk per unit = distance × value per price point. Units = risk budget / account risk per unit. Unlevered capital = units × entry × value per point.

Common mistakes and edge cases

ATR is entered manually; no market data is fetched. The value-per-point field must match the instrument and account currency. Default 1 is not universal. Round units down to a valid lot step; verify FX conversion, fees, slippage and margin separately. Long stops at or below zero are rejected.

How to use

Enter capital and select risk percentage or fixed risk amount.
Enter entry, ATR and multiplier, then long or short direction.
Set account-currency value per price point per unit; inspect stop, size and unlevered capital.

Example

Capital 10,000, risk 1%, entry 100, ATR 2, multiplier 1.5 and value per point 1 gives distance 3, long stop 97, risk budget 100, about 33.333333 units and 3,333.33 unlevered capital. A short stop is 103.
