Perpetual Futures

A Perpetual Futures is a derivative contract in cryptocurrency trading without an expiration date. Traders speculate on the future price of an asset, such as Bitcoin or Ethereum, using leverage without owning the underlying asset. Also called perps or perpetual swaps, these contracts mimic traditional futures but allow indefinite holding.

Traders open long positions to bet on price increases or short positions for decreases. Exchanges use a funding rate mechanism to keep the perpetual contract price aligned with the spot market price. Every few hours, longs pay shorts if the contract trades at a premium, or vice versa if at a discount. Leverage amplifies gains or losses; for example, 10x leverage on a 1% price move yields 10% profit or loss. A mark price based on multiple exchange spot prices prevents manipulation and triggers liquidations.

Perpetual futures dominate crypto derivatives trading, with daily volumes often exceeding spot markets on platforms like Binance and Bybit. They enable 24/7 hedging against price volatility and leveraged speculation. Key characteristics include:

• No expiry date: Positions stay open indefinitely.
• High leverage: Up to 125x on some exchanges.
• Funding rates: Periodic settlements, typically every 8 hours.
• Liquidation risks: Automatic closure if margin falls below maintenance levels.

These contracts matter in crypto for providing liquidity and price discovery. However, leverage heightens risks, including total loss from liquidations. Traders must monitor funding rates and use risk management like stop-loss orders to secure positions.
