Understanding Perpetual Futures Contracts
Perpetual futures are innovative derivative products that combine features of traditional futures with the flexibility of spot markets. Unlike conventional futures contracts which have fixed expiration dates, perpetual futures:
- Never expire: You can hold positions indefinitely
- Track index prices closely: They mirror margin-based spot market behavior
- Offer amplified returns: While increasing potential risks
- Use funding rate mechanism: To maintain price alignment with underlying assets

BTC vs. USD Denominated Contracts
Phemex offers two contract types with distinct characteristics:
BTC-Based Contracts
- Contract value: 1 USD worth of Bitcoin (calculated as 1USD/BTC price)
- P&L calculation: In BTC terms
- Nonlinear functions: Profits/losses change at variable rates
- Example:
Profit = (1USD/Open BTC price - 1USD/Close BTC price) × Quantity
USD-Based Contracts
- Contract value: Varies by asset (e.g., 0.005 ETH for ETHUSD)
- P&L calculation: In USD terms
- Linear functions: Consistent rate of change
- Example:
Profit = (Close Price - Open Price) × Quantity
