Start with the mental model

A perpetual follows price, not a finish line.

A perpetual contract is designed to give you continuous exposure to an underlying market without a scheduled expiration. You can open a long position when you expect the price to rise, or a short position when you expect it to fall.

01OpenChoose a contract, direction, size, and price.

02MonitorTrack mark price, margin, funding, and risk.

03CloseExit the position when your strategy says it is time.

No expiry does not mean no risk. Margin, funding, price movement, and liquidation rules can affect a position while it is open. Read the contract and account requirements before sending a live order.

Choose the right instrument

Three ways to express a market view

The cleanest way to choose an integration is to start with what you want your position to represent.

Build with Perpetuals

Start with the data your risk system needs.

Perpetuals integrations are not complete when an order is accepted. They are complete when your system can explain the position, its collateral, and the costs and risks that change over time.

Choose an interface

Use the surface that fits your workflow.

Start with REST to discover and reconcile. Add WebSocket or FIX when your system needs streaming or institutional connectivity.
