The fees and keeper deposit would be shown, and the user can check the fees before opening the position. Clicking on Long/Short will open the position and will be available in the position tab.
There is also a "funding rate" that is deducted over time as fees.

After opening the position, the trade comes on positions, and the trader can manage the trades on this tab. The trader can view their position size, open price, Liquidation price, and PnL on this tab.
If the trader opens another trade, then the exchange automatically averages both orders, recalculates the PnL and shows it in the position tab.
Also, the history tab will allow the traders to view all the trades on the exchange made by the user.

Expired Order

Expired order is a order that has not been filled and has reached its expiry time.
User need to cancel the expired order first to open another order on the platform.

Closing a position

To close the trade, the user can go to positions and click on the "close position", and after the transaction is made, the order will be closed and PnL will be realised according to the trade outcome.
The profit/loss will be credited to the wallet address after collecting all fees by exchange, and no fees will be deducted from the portfolio after the final transaction.


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. because 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.
