How this is calculated
- Risk budget = account balance × risk % ÷ 100 (or your fixed amount).
- Ticks to stop = |entry − stop| ÷ tick size. Pips are shown only when the instrument defines a pip size.
- Loss per lot = (stop distance + spread/slippage) ÷ tick size × tick value, converted into your account currency with the rate you enter, plus commission.
- Theoretical size = risk budget ÷ loss per lot. It is then rounded down to the quantity increment so the rounded risk never exceeds the budget.
- Reward = (|take profit − entry| − spread) priced the same way, minus commission. R:R = net reward ÷ net risk per lot.
Quantity is expressed in the instrument’s quantity unit (lots); one lot represents the contract size shown above, which varies by broker. Swaps, gaps, and margin are excluded. Results are estimates for education, not order execution instructions.
