For same trading pair and side (long/short), only one order can be placed.Orders of the same direction will be combined into one position.
The limit order will affect the position in the same direction of the same trade pair. The image below shows the impact of limit order on positions in the same direction and with the same trading pair.
The original position size can be increased or descreased by using limit order in same trading pair and side.

Take Profit and Stop Loss
In the manage tab, you can set TP/SL to take profit or stop loss at certain price point.
After setting TP/SL, the price will be shown on the position list.
Reminder
The maximum profit on one position is 900% in RUSD pool.
The maximum loss on one position is -90% in RUSD pool.
So users can set TP/SL between -90% and 900% by themselves (included -90% and 900%)
If you close the original position manually, the unexecuted orders will automatically be closed, and the unused fees will be returned.
Closing a position
You can close a position partially by clicking on the "X" button,
Close a position partially will reduce size and keep leverage the same: only the size of the trade is affected (Position Size, Collateral Value, Net Value), and not the Leverage or Liquidation Price.
The image below shows the impact of closing 50% of an open position whilst keeping leverage the same
Close a position completely means that the position will be closed at the current market price.
Liquidations
The Liquidation means that the positions will be automatically closed when the following occurs:
1. Liquidation is executed when the minimum collateral value is less than 10% of the position: Minimum collateral value = (collateral - opening fee) * leverage / 10
2. Liquidation is executed when the Minimum Collateral - Closing Fee - Borrow Fee - Liquidation Fee(5U) ≤ 0.
How to caculate the Liq.price
Size = (collateral - open fee)*leverage
Fee = PositionFee + HourlyFee - Founding fee
Liq.price (long) = entry peice*[1-(initial collateral*0.9 - hourly fee - position fee + founding fee)/(initial collateral*leverage)]
Liq.price(short) = entry price*[1 + (initial collateral*0.9 - hourly fee - position fee + founding fee)/(initial collateral*leverage)]
