Exchange rules

Crypto-margined expiry/perpetual futures default to USD as the quote currency. If you select another currency to quote prices, the USD price is converted according to the system exchange rate. Crypto-margined options default the crypto as the quote currency. If you select another currency to be the quote currency, we will convert the crypto into USD according to the index price, then convert USD into your selected quote currency based on the system exchange rate.

The system exchange rate is calculated using the average bank exchange rate for the past 14 days. When the rate deviates more than 0.2% on delivery day, the rate defaults back to the 14-day average.

The displayed amount varies with the system exchange rate. It won't affect the actual amount of your contracts.
