What Are Perpetual Contracts?
Risk Warning Perpetual contract trading involves substantial risk of loss due to leverage. You can lose more than your initial investment. This guide is for educational purposes only and is not financial advice.
A perpetual contract (also called a "perp" or "perpetual swap") is a type of derivative that lets you trade the price of a cryptocurrency without owning it and without an expiration date.
Unlike traditional futures contracts that settle on a specific date, perpetual contracts can be held indefinitely. This makes them the most popular trading instrument in crypto — accounting for over 60% of all crypto trading volume.
Why "perpetual"? Traditional futures expire quarterly. Crypto traders wanted a way to hold leveraged positions without constantly rolling contracts to the next expiration. Perpetual contracts solve this by replacing expiration dates with a funding rate mechanism that keeps the contract price anchored to the spot price.
Perpetual contracts were pioneered by BitMEX in 2016 and have since become the standard across every major crypto exchange including Binance, Bybit, OKX, and Bitget.
How Perpetual Contracts Work
Deposit Margin
You deposit collateral (usually USDC or USDT) as margin to open your position.
Choose Your Pair & Leverage
Select a trading pair (e.g. BTCUSDC) and set your leverage multiplier.
Open a Position
Go long if you expect the price to rise, or short if you expect it to fall. Your position size = margin × leverage.
Funding Rates Are Exchanged
Every 8 hours a funding payment is made between longs and shorts to keep the contract price near spot.
Close Your Position
Close anytime to realize your profit or loss. There is no expiration forcing you out.
Funding Rates Explained
✓ 📈 Positive Funding Rate
Perpetual price is above spot price (bullish market). Longs pay shorts. This incentivizes more short positions to bring the price back down.
✓ 📉 Negative Funding Rate
Perpetual price is below spot price (bearish market). Shorts pay longs. This incentivizes more long positions to push the price back up.

Leverage & Margin
✓ Isolated Margin Lower Risk
Only the margin allocated to a specific position is at risk. If liquidated, you lose only that margin — not your entire account balance.
✓ Cross Margin Higher Risk
Your entire account balance acts as margin for all open positions. Provides more flexibility but a single bad trade can wipe your full account.
✓ Low Leverage (2x–5x) Recommended
Recommended for beginners. Smaller amplification of gains and losses. Wider buffer before liquidation.
✓ High Leverage (20x–125x) Expert Only
Available on major pairs like BTCUSDC. Amplifies both profits and losses dramatically. Small price moves can trigger liquidation.
Liquidation Mechanics
Margin Ratio Falls
As the market moves against your position, your unrealized losses reduce your effective margin balance.
Maintenance Margin Threshold
Exchanges require a minimum maintenance margin (typically 0.5%–1% of position). When your margin falls below this, liquidation is triggered.
Position Is Closed Forcibly
The exchange's liquidation engine closes your position at the best available market price. Any remaining margin may be taken as a liquidation fee.
Insurance Fund
If your position is liquidated below the bankruptcy price, the exchange's insurance fund covers the shortfall to protect counterparties.

Trading Tips
Start with low leverage (2x–5x) until you understand liquidation mechanics.
Always set a stop-loss before opening a leveraged position.
Monitor the funding rate before entering — a high positive rate means longs are paying significantly.
Use isolated margin to cap your maximum loss per trade.
Never risk more than 1%–2% of your account on a single trade.
Track open interest and funding rates as sentiment indicators.
Understand that you do NOT own the underlying crypto when trading perps.

Derivatives & Leveraged Products — Important Risk Warning
Derivatives are complex financial instruments that carry a high risk of rapid capital loss. Leveraged trading (futures, perpetual contracts, margin trading, options) can result in losses that exceed your initial investment. The majority of retail investor accounts lose money when trading derivatives.
You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.
In the European Union, crypto derivatives are classified as financial instruments under MiFID II. Only platforms with appropriate MiFID II authorization may offer these products to EU residents. Regulatory treatment varies by jurisdiction — verify the legal status of derivatives trading in your country before participating.
