Deepcoin adopts two types of margin systems, namely, a cross model and an isolate model.
The maximum loss of an isolated position is the initial margin and margin call (if any) used by the position. If a position encounters a forced liquidation, the holder will only lose the position margin of the isolated position, and the available balance of the account will not be added. Holders can manually add margin to enter an isolated position, reduce the actual leverage of the position, and optimize the liquidation price. After the position is called for margin, if the holder adjusts its leverage, the previous margin call will be reset to 0.
The available balance of all accounts in the trading account can be fully called by the cross position to avoid forced liquidation. The unrealized profit and loss of all contract positions in the full position mode are shared, that is, the open profit increases the available balance of the account, and the open loss reduces the available balance of the account. The available balance can be used as margin to open new positions and is also the upper limit for the taker. When a position is switched from an isolated position to a cross position, if there is a two-way position, it will be switched to a cross position at the same time.
When a cross position is switched to an isolated position, it can only be switched when one-way or no position is held, that is, a cross position of a two-way position cannot be switched to an isolated position (to avoid forced liquidation when switching to an isolated).
In currency standard contract trading, holders can hold long and short double positions at the same time. In each contract, all long positions are combined and all short positions are combined. When long and short two-way positions are held, the two-way positions need to occupy the corresponding initial margin according to the margin ladder.
