Create Free Account →Risk management is what separates traders who survive from traders who blow accounts. A position sizer takes the guesswork out of every trade.
Risking too much on a single trade is the fastest way to blow an account. Enter your risk % and stop loss distance — the calculator shows the lot size that matches that risk.
A 20-pip stop on EUR/USD and a 20-pip stop on XAU/USD don't risk the same dollar amount. The calculator accounts for pip values per instrument so your risk stays consistent.
Trading a USD-quoted pair from an AUD account? The calculator uses live exchange rates to convert pip values into your account currency so the sizing is accurate — not off by 30%.
The calculator covers 11 forex and metals instruments (the major forex pairs, XAU/USD and XAG/USD) and 8 futures contracts (NQ, ES, GC and SI, in standard and micro sizes). The version inside The Trading Terminal also covers WTI, US30, US500, GER40, BTC/USD and ETH/USD. Pip values and contract specs are built in. The position size guide walks through the formula step by step.
Choose XAU/USD, enter your account size, risk % and stop loss in pips, and the calculator returns the lot size using the pip value and contract size built in for gold. A pip on gold is not worth the same as a pip on EUR/USD, which is why a separate XAUUSD lot size is needed. Check the result against your broker's contract specification, because some brokers define gold lots differently. For futures, GC (Gold) and MGC (Micro Gold) are also available.
NAS100 is the name many CFD brokers use for the Nasdaq-100. This calculator covers the CME NQ E-mini and NQ Micro futures contracts for that index rather than a broker's NAS100 CFD, because CFD point values differ between brokers. If you trade the NAS100 CFD, check your broker's value per point and use the same position size formula shown below.
