How Perps Work
A Perps trade starts as an order in the order book. When it fills, it becomes a position whose value changes as the tracked market moves, until the trader closes it or the system closes it because the account can no longer support the risk.Prices
A Perps market has a traded price from the order book and reference prices
used by the system. The index price tracks the underlying asset, while the
mark price is used for account equity, margin checks, and liquidation risk.
Trading Positions
Trading a Perps market creates or changes a position. A long position benefits
when the tracked asset rises, and a short position benefits when it falls.
Orders trade through the order book; fills update the account’s position,
balance, and history.
Margin And Liquidation
Perps require collateral to support open positions. That collateral is the
account’s margin: the buffer that covers losses while a position is open. If
account equity falls too far relative to the required margin, the position can
be liquidated to close exposure.
Funding Payments
Funding payments keep the contract price close to the index price. When a
market trades above its index price, long positions generally pay short
positions. When it trades below its index price, shorts generally pay longs.
