Liquidations
When the trader does not have enough funds to meet the margin requirement, which is the amount of collateral that the trader must keep on deposit in order to maintain their open positions. In this case, the exchange will automatically liquidate the trader's positions to bring their account back within the required margin.
The liquidation price will be shown in the positions tab and if you are using more than 5x leverage, then always try to check the asset underlying price. The more leverage you take, the more chances are there for liquidation due to the volatility in the assets.
If there is any collateral remaining after deducting losses and fees, then the corresponding amount would be returned to your trading account.
