Contract holding mode:
Single position mode and full position mode
Full position: The mode in which the entire account balance is used as margin. If a loss occurs, all funds in the account will be used as risk collateral.
Single position: Each position calculates margin independently. Position losses will only affect the margin in the position and will not affect other funds in the account. In the single position mode, the profit and loss of a position cannot be offset by other positions. Once the margin is lost, the position will be liquidated, and other positions will not be affected.
Default margin of single position mode = position holding volume ✖️ opening price ➗ leverage multiple
Maximum opening volume:
Assume: There is 1,000 US dollars in the contract account, open a full position 5 times, and prepare to open a long Bitcoin. At this time, the Bitcoin price is 70,000
Maximum position = contract account funds ✖️ leverage multiple ➗ coin price
At this time, the maximum position is:
1000✖️5➗70000≈0.071BTC
The liquidation price is:
Forced liquidation price = opening price ➖ position direction ✖️ margin ➗ position volume ✖️ 0.995
Forced liquidation price = 70000-1✖️1000➗0.071✖️0.995 = 55986
