The calculation method of the required margin for cryptocurrency CFD is as follows.
Margin requirement = trading volume x contract size (*different for each issue) x trading price ÷ leverage (up to 100 for Cryptocurrency CFDs)
If the base currency is different from the margin currency, the above result (amount in the margin currency) will be converted by the rate with the base currency. If the leverage set for the account is 100 or less, the account leverage will be applied.
You can check the contract size by right-clicking (PC) or tapping (smartphone) on the issue on the MT4/5 quote display. Refer to the examples below:
Example) Trade 1 lot of BTCUSD (contract size = 1) at a market price of 23,000 USD
= 1 (lot) x 1 x 23,000 x 1 ÷ 100 = 230 USD
Example) Trade 2 lots of BCHUSD (contract size = 10) at market price 125 USD
= 2 (lots) * 10 * 125 * 1 ÷ 100 = 25 USD
Example) Trade 1 lot of ETHJPY (contract size = 1) at a market price of 215,000 JPY
= 1 (lot) × 1 × 215,000 × 1 ÷ 100 = 2,150 JPY
Example) Trade 1 lot of XRPJPY (contract size = 10,000) at market price 70.50 JPY
= 1 (lot) x 10,000 x 70.50 x 1 ÷ 100 = 7,050 JPY
Example) Micro account: Trade 5 lots of BTCUSD-m (contract size = 0.1) at market price 23,000 USD
= 5 (lots) x 0.1 x 23,000 x 1 ÷ 100 = 115 USD
