Position size calculator
Your balance, your risk %, your entry and your stop: you get the exact number of lots. Forex, crosses and gold.
Position size
0.40 lots
Rounded down to the nearest 0.01 lot so you never exceed your risk.
How the size is calculated
Amount at risk = balance × risk %. Loss per lot = distance between entry and stop × contract size (100,000 units in forex, 100 ounces for gold), converted into your account currency. Number of lots = amount at risk ÷ loss per lot.
Example: $100,000 account, 0.25% risk ($250), short NZD/USD at 0.58892 with a stop at 0.59128 (23.6 pips): 250 ÷ (0.00236 × 100,000) = 1.059, so 1.05 lots rounded down.
FAQ
How much should I risk per trade? Most prop firm traders risk between 0.25% and 1% per trade: enough for wins to matter, little enough to survive a losing streak.
Why a conversion rate on crosses? On EUR/GBP with a dollar account, the loss is in pounds: you need the GBP/USD rate to convert it into dollars.
What about indices? Index contract sizes vary from broker to broker: check your broker's contract specification before using it here.
