How is Margin calculated on MT4?
The formula is as follows:
Lots x Contract Size x Margin%,
or, (Lots x Contract Size) / Leverage
You can find all Contract Sizes , by right-clicking on any Symbol through MT4’s market watch and then ‘Specification’
重要提示: Margin is always denominated in the Base Currency
| 符号 | Base Currency | Quote Currency |
| 欧元/美元 | 欧元 | 美元 |
| 美元/日元 | 美元 | 日元 |
| 英镑/美元 | 英镑 | 美元 |
Examples:
If you wish to Buy 1 lot on EURUSD with a margin percentage of 0.2%, then:
Margin Requirement = 1 (Lot) x 100,000 (Contract Size) x 0.2% =200 EUR
If you wish to Buy 1 lot on USDJPY with a leverage of 1:500, then:
Margin Requirement = 1 (Lot) x 100,000 (Contract Size) / 500 =200 USD
The final amount depends on your account’s currency.
If your account is in a different currency than the base currency of your traded instrument, then a conversion will happen to reflect the appropriate margin.
