Trade
Perpetuals
A type of derivative contract with no expiration date, allowing traders to speculate on the price of an asset over time.
Entry price
The average price at which your position was opened, weighted by size and direction (long/short).
Mark price
A fair price used to calculate PnL and liquidation. It’s derived from external price feeds and helps prevent manipulation.
Open interest
The total number of active perpetual contracts (long and short) that have not yet been closed or settled.
PnL (Profit and Loss)
Shows how much profit or loss your position has gained or lost.
Unrealized PnL
The potential gain or loss if your open position were to be closed at the current mark price.
Realized PnL
The actual profit or loss you’ve made from closed positions.
Leverage
The multiplier used to increase position size relative to your margin. For example, 10x leverage allows a $100 margin to control a $1,000 position.
Margin
The collateral required to open and maintain a position. More leverage means less margin required, but also more risk.
Isolated Margin
A margin system where the collateral is limited to a single position, so losses are contained and don’t affect your whole account.
Maintenance Margin
The minimum amount of collateral required to keep a position open before it gets liquidated.
Funding Rate
A recurring payment between long and short traders to keep the contract price in line with the spot price.
Liquidation
Occurs when your position’s losses approach your margin amount. If your position hits the liquidation price, it’s force-closed to prevent going negative.
