To enhance user’s trading experience, AscendEX has implemented multi-asset collateral mechanism for perpetual futures contracts, or futures, supporting multiple assets for margin requirement.
I. Futures Margin Requirements
Multi-asset collateral mechanism supports different assets - BTC, ETH, USDT, BCH, DOT, LINK, USDC, PAX, XRP, BNB, MATIC, TRX, ADA, UNI, ETC, FIL, FTT, VET and etc for margin requirementsin the futures trading. As futures PL is calculated in USDT, a negative USDT value will be displayed in the asset balance when users incur a trading loss with only non-USDT collateral in their futures accounts, and a positive USDT value displayed for trading profit.
Here is an example: Assume a futures account has an asset balance of 1 BTC. When there is position loss of 1,000 USDT, the asset balance will be displayed as 1 BTC and -1,000 USDT.
1. Collateral Calculation for Futures Trading
The USDT value of collateral in the futures account is calculated by applying the Discount Factor, or haircut, to those transferred with Discount Factor per the following formula:
Collateral = Asset * Index Price * Collateral Discount Factor;
