After getting to know the definition and DueDEX's features about a Perpetual Swap Contract, you should be aware of some key components:
1. Position Marking: DueDEX is using Fair Price Marking mechanism as position marking. The mark price determines Unrealized PNL and Liquidation Price.
2. Initial and Maintenance Margin: These essential margin levels determine how much leverage one can trade with and at what point liquidation occurs.
3. Funding: The mechanics of Funding ensures the price of Perpetual Swap on DueDEX to track the underlying Index Price closely. Periodic payments exchanged between the buyer and seller every 8 hours. If the rate is positive, the long position holders will pay the short position holders payment, and vice versa if the rate is negative.
4. Funding Timestamp: 04:00 UTC, 12:00 UTC and 20:00 UTC every day. You will only pay or receive the funding if you hold a position at that Funding Timestamp. If you close your position before Funding Timestamp, you don’t have to pay/receive funding payment.
