## What is TradeSize?

Risk exactly what you planned on every trade, down to the last lot step.

TradeSize is a precise position size calculator for forex and CFD traders. Enter your risk amount, entry price, stop loss and contract size, and it returns the correct lot size instantly. No spreadsheets and no mental maths before you click buy or sell.

THE MATHS, DONE PROPERLY
Lot size is calculated as risk divided by stop distance multiplied by contract size. The result is always rounded DOWN to your broker's lot step (0.01, 0.1 or 1), so rounding never pushes you over your risk limit.

INSTRUMENTS READY TO GO
Choose from 28 forex pairs plus gold, silver, major indices, oil, natural gas, Bitcoin and Ethereum. Each comes with a preset contract size, and you can adjust it to match your broker's specification.

AUTOMATIC CURRENCY CONVERSION
Trading a pound-denominated account on USD-quoted gold or a yen cross? When your account currency differs from the instrument's P/L currency, TradeSize converts your risk using daily reference rates. Prefer your broker's live quote? Override the rate manually.

LIVE PREVIEW, FREE
The lot size updates as you type, so you can test different stop placements and risk amounts in seconds. The live preview is free to use.

FULL RESULTS WITH TRADESIZE PRO
Pro unlocks the full result screen with a complete trade breakdown, so you can check every figure behind your position before you place it.

PRIVATE BY DESIGN
No account, no tracking and no ads. Every calculation stays on your device.

### 5/5 — Very helpful

*2026-10-23*

An outstanding tool for accurate position sizing and risk management, particularly when trading XAU/USD (Gold). It makes calculating the correct lot size based on account balance, risk percentage, and stop-loss distance incredibly simple and efficient. Highly recommended for traders looking to improve precision, maintain consistent risk management, and eliminate guesswork when executing trades, it’s very very helpful for me and means I don’t have to have a pen a paper and a calculator trading very helpful
