Isolated Margin: You can adjust margin (increase / decrease margin)
Cross Margin: Margin adjustment is not supported. But you can adjust the balance of the contract account by "fund transfer" to "contract account”.
Margin increase / decrease:
Only affect your: position margin, actual leverage ratio, rate of return, force liquidation price.
Current position: number of contracts, average opening price, realised profit and loss, position value and unrealised profit and loss are not affected.
Transfer funds from the available balance of contract account to position margin;
The position margin increases, the actual leverage ratio decreases, the return rate decreases, and it is more difficult to be forced liquidated, and the forced liquidated price is far away from the current fair price. More ability to withstand market changes.
The reduced margin will be returned to the available balance of your contract account;
The position margin is reduced, the actual leverage ratio is increased, the return rate is higher, it is easier to be forced liquidated, and the forced liquidation price is closer to the fair price. Can't bear the change of market.
