Dcoin Perpetual Swap is a virtual derivative product that is settled in digital tokens USDT. Each contract has a face value of fixed amount of digital token(e.g BTCUSDT contract has a face value of 0.0001 BTC). Traders can long a position to profit from the increase of a digital asset's price, or short a position to profit from the decline of a digital asset's price.
- Perpetual Swap has no delivery date and never expires;
Funding : as there is no delivery date, a funding mechanism is used to ensure that the Perpetual Swap price is anchored to the spot market; The calculation time of funding is 8:00, 16:00 and 24:00 (HKT) every day, and the funding is recorded in the realized profits and losses;
- Mark Price : a mark price is used to calculate users' Unrealized Profits and Losses (UPL) in order to reduce unnecessary liquidation in volatile market conditions;
- Daily Settlement : a daily settlement process (at HKT 16:00) moves Unrealized PnL into Realized PnL, increasing flexibility of capital utilization;
- Forced Liquidation : when the margin ratio+ Forced-Liquidation Fee Rate is lower than the maintenance margin ratio, our system will liquidate the user's positions.
