Do the arithmetic before the trade.
Four calculators that answer the questions which decide the size of a position: how much margin, what a tick is worth, how many lots to risk, and what the trade pays.
Results are indicative. Contract specifications, account currency conversion and swap are applied by the platform at execution.

The formulas
What the calculator is doing.
| Calculation | Formula | Watch out for |
|---|---|---|
| Margin | (Lots × contract size × price) ÷ leverage | Price is in the quote currency |
| Tick value | Tick size × contract size × lots | Gold and indices have different contract sizes |
| Position size | Risk amount ÷ (stop ticks × tick value per lot) | Slippage makes realised risk higher |
| Profit / loss | (Exit − entry) × contract size × lots × direction | Excludes spread, commission and swap |
All values assume the quote currency is USD. For crosses, convert the quote-currency value to the account currency at the prevailing rate.

FAQ
Calculator questions.
Why does my platform show a different margin?
The platform uses the live price, your account currency conversion and the leverage tier applied to your equity. The calculator uses the values you enter and assumes USD.
Which stop distance should I enter?
The distance from entry to the structural level that invalidates the trade, plus the spread and expected slippage — not the distance you would like to risk.
Does the position size include commission?
No. The risk budget covers price movement only. Deduct commission and swap separately when comparing the expected cost of a trade.
Can I use these for crypto CFDs?
Yes, choose the BTCUSD preset or a custom contract. Confirm the contract size and tick value in the terminal before trading any instrument not listed.
