Perpetual contracts are the most popular product in Binance futures trading — with no expiry date, you can open and close positions at any time. If you don't have a Binance account yet, register a Binance account to experience a world-class futures trading system. Also recommended: get the Binance APP to monitor your positions on the go.
Basic Concept of Perpetual Contracts
A Perpetual Contract is a special type of futures contract. The key difference from traditional futures is that it has no expiry date. Traditional futures must be settled on the delivery date, but perpetual contracts can be held indefinitely as long as your margin is sufficient.
This design makes trading far more flexible — you don't need to worry about contract expiration and can enter or exit the market at any time based on your judgment.
Core Mechanisms of Perpetual Contracts
Funding Rate Mechanism
Since perpetual contracts have no expiry date, how does the contract price stay close to the spot price? The answer is the funding rate.
The funding rate is settled every 8 hours (typically at UTC 0:00, 8:00, and 16:00), with the following rules:
- When the contract price is above the spot price, the funding rate is positive, and longs pay shorts
- When the contract price is below the spot price, the funding rate is negative, and shorts pay longs
This mechanism causes both sides to auto-adjust, pulling the contract price back toward the spot price.
Mark Price
Binance uses the Mark Price rather than the last traded price to determine liquidation triggers. The Mark Price aggregates price data from multiple exchanges, effectively preventing unreasonable liquidations caused by abnormal volatility on a single exchange.
How to Trade Perpetual Contracts
Step 1: Enter the futures trading interface
Open the Binance APP and find the "Futures" entry in the bottom navigation — the default view shows USDT-margined perpetual contracts.
Step 2: Select a trading pair
Use the search bar at the top to select the token you want to trade, such as BTCUSDT Perpetual. Beginners should choose mainstream tokens with good liquidity and low slippage.
Step 3: Set leverage
Tap the leverage multiplier button to adjust. Beginners should use 5x or less. Higher leverage requires less margin but carries greater risk.
Step 4: Choose margin mode
- Cross Margin: All available balance serves as margin — harder to liquidate, but losses are larger if liquidation occurs
- Isolated Margin: Only a specified amount serves as margin — maximum loss is limited to that amount
Beginners should use isolated margin for more controllable risk.
Step 5: Open a position
Choose Long or Short, set the price and quantity, then submit the order. You can choose a limit order (execute at a specified price) or a market order (execute immediately at the best available price).
Step 6: Manage your position
After opening a position, check the "Positions" tab for details including unrealized P&L, liquidation price, and margin ratio. Always set take-profit and stop-loss.
Common Perpetual Contract Strategies
Trend Trading: Go long in uptrends and short in downtrends. This is the most fundamental approach, and works even better combined with technical analysis.
Arbitrage Strategy: Profit from funding rates. When the funding rate is high, go long spot and short futures to steadily collect funding rate income.
Hedging: If you hold a large spot BTC position and worry about short-term price drops, open an equivalent perpetual short position to hedge price risk.
Swing Trading: Go long near support levels and short near resistance levels, profiting repeatedly.
Important Considerations
- Monitor the funding rate: Check the current funding rate before each settlement — high rates mean high holding costs
- Watch the liquidation price: Immediately after opening a position, confirm how far your liquidation price is from the current price
- Don't go all-in: Keep sufficient balance in your futures wallet to handle market fluctuations
- Set price alerts: Use Binance's price alert feature to get notified when prices approach key levels
- Use take-profit and stop-loss wisely: Plan exit conditions for every trade in advance — don't trade on feelings
Perpetual contracts are currently the most flexible derivative tool in the crypto market. Mastering them adds more possibilities to your trading strategy. But remember — high flexibility also means high risk. Always trade cautiously with a thorough understanding of the rules.
