What Are Perpetual Futures? A Complete Beginner's Guide

Perpetual futures contracts, commonly known as "perps," are crypto derivative instruments that let traders speculate on the price of Bitcoin, Ethereum, and hundreds of other cryptocurrencies without ever owning the underlying asset. Unlike traditional futures that expire on a set date, perpetual futures have no expiration, meaning you can hold a long or short position for as long as you maintain sufficient margin. First introduced by BitMEX in 2016, perpetual futures now dominate crypto trading volume, regularly surpassing spot markets by a factor of three or more. This guide covers everything you need to know about how perpetual futures work, from funding rates and leverage to liquidation mechanics and the differences between centralized and decentralized exchanges.

How perpetual futures differ from traditional futures

Traditional futures contracts, such as the quarterly Bitcoin futures on CME, settle on a fixed date. When the contract expires, positions are either physically delivered or cash-settled, and a new contract begins trading. This creates predictable settlement cycles but also forces traders to roll positions between contracts, incurring additional costs and complexity.

Perpetual futures eliminate the expiration problem entirely. There is no settlement date, no rolling, and no convergence forced by time. Instead, perpetual contracts use a mechanism called the funding rate to keep the contract price anchored to the underlying spot price. This design makes perps simpler to trade and more capital-efficient than their traditional counterparts.

The result is an instrument that behaves like a leveraged spot position with an ongoing carry cost or income depending on market conditions. Traders get the simplicity of spot trading combined with the capital efficiency and directional flexibility of derivatives.

The funding rate mechanism explained

The funding rate is what makes perpetual futures work. Since there is no expiration to force the contract price toward spot, funding rates create an economic incentive for convergence. Every eight hours on most exchanges (some protocols use continuous or hourly funding), a payment is exchanged between long and short traders.

When the perpetual price trades above the spot price, long traders pay short traders. This positive funding rate discourages excessive long positioning and encourages shorts, pulling the perp price back toward spot. When the perpetual price trades below spot, the opposite happens: shorts pay longs, incentivizing buying and pushing the price up toward spot.

The funding rate calculation typically involves two components. The interest rate component reflects the borrowing cost differential between the base asset and the quote currency. This is usually a small, fixed value. The premium index measures how far the perpetual price deviates from the spot price, calculated as a time-weighted average. The combination of these two components produces the final funding rate that traders pay or receive.

For traders, funding rates represent a real cost or income stream. A funding rate of 0.01% every eight hours translates to roughly 0.03% per day or about 10.95% annualized. During extreme market conditions, funding rates can spike to 0.1% or higher per eight-hour period, making it very expensive to hold positions on the crowded side. You can track live funding rates across all major exchanges on our funding rates dashboard. For a deeper understanding, read our complete guide on how to read funding rates.

Understanding leverage in perpetual futures

Leverage is what makes perpetual futures both powerful and dangerous. It allows you to control a position larger than your deposited collateral. With 10x leverage, a $1,000 deposit controls a $10,000 position. This means a 5% price move in your favor generates a 50% return on your margin, but a 5% move against you results in a 50% loss.

Most perpetual futures exchanges offer leverage ranging from 1x to 125x, though using maximum leverage is extremely risky and not recommended for anyone. Professional traders typically use between 2x and 10x leverage, with many defaulting to 3x to 5x for most trades.

Leverage selection should be based on your trading timeframe and risk tolerance. Scalpers trading minute-by-minute price movements might use higher leverage because their stop losses are tight. Swing traders holding positions for days or weeks should use lower leverage to accommodate wider price fluctuations without risking liquidation.

The key insight about leverage is that it does not change your profit in dollar terms if you hold position size constant. A $10,000 BTC long position generates the same dollar profit whether you fund it with $10,000 at 1x or $1,000 at 10x. The difference is capital efficiency and liquidation risk. Higher leverage frees up capital but narrows the distance to your liquidation price. For beginners, our leverage trading guide provides a practical framework for choosing the right multiplier.

How liquidation works

Liquidation is the forced closure of your position when your remaining margin falls below the maintenance margin requirement. It is the single biggest risk in perpetual futures trading and the primary reason most beginners lose money.

Every exchange sets a maintenance margin percentage, typically between 0.5% and 5% depending on the asset and position size. When your unrealized losses erode your margin down to this threshold, the exchange liquidation engine takes over your position and closes it to prevent further losses.

The liquidation price depends on three factors: your entry price, your leverage, and the maintenance margin rate. For a long position with 10x leverage and a 0.5% maintenance margin rate, your liquidation price is approximately 9.5% below your entry. At 20x leverage, it narrows to roughly 4.75%. At 50x leverage, a mere 1.9% adverse move triggers liquidation.

Different exchanges handle the liquidation process differently. Some use full liquidation where your entire position is closed at once. Others use partial liquidation, closing only enough of the position to bring your margin back above the maintenance threshold. Partial liquidation is generally friendlier to traders and is becoming the industry standard.

To manage liquidation risk, always use stop-loss orders placed well above your liquidation price, start with conservative leverage, and use our position calculator to model your liquidation level before entering any trade.

DEX vs CEX for perpetual futures trading

Decentralized perpetual futures exchanges (perp DEXes) and centralized exchanges (CEXes) each offer distinct advantages, and understanding the tradeoffs helps you choose the right platform for your needs.

Centralized exchanges like Binance, Bybit, and OKX offer deep liquidity, fast execution, advanced order types, and polished user interfaces. They support hundreds of trading pairs and provide tools like portfolio margin that maximize capital efficiency. The downside is custodial risk: you must trust the exchange with your funds. The collapse of FTX in 2022, which wiped out billions in customer deposits, demonstrated how catastrophic this risk can be.

Decentralized exchanges like Hyperliquid and dYdX let you trade from a self-custody wallet. Your collateral sits in smart contracts, not in a company bank account. There is no KYC requirement, no account creation, and no centralized entity that can freeze your funds or become insolvent with your money. The code is typically open source and audited, providing transparency that centralized platforms cannot match.

The gap between DEX and CEX performance has narrowed dramatically. Hyperliquid now processes thousands of transactions per second with sub-second finality, matching the speed of most centralized exchanges. Liquidity on major pairs like BTC and ETH has grown to levels where slippage is minimal for all but the largest orders. For most retail traders, the self-custody benefits of DEXes now outweigh the marginal performance advantages of centralized platforms.

Key differences between DEX and CEX perp platforms

Beyond custody, several practical differences affect your trading experience. Fee structures vary, with DEXes often offering lower taker fees and sometimes providing trading fee rebates through token incentives. CEXes typically have tiered fee structures that favor high-volume traders.

Oracle design matters on DEXes. Pool-based platforms like GMX and Jupiter Perps use external oracle prices to settle trades, which can create different dynamics than order book platforms where prices are set by market participants. Order book DEXes like Hyperliquid and dYdX function more similarly to centralized exchanges in terms of price discovery.

Margin modes differ too. Most CEXes offer both cross-margin and isolated margin with flexible switching. Some DEXes default to cross-margin or have specific rules about margin modes that may affect your trading strategy. Understanding these nuances before you start trading prevents costly surprises.

How to get started with perpetual futures

Getting started with perpetual futures trading involves several steps, and taking the time to prepare properly will save you from expensive mistakes.

First, educate yourself thoroughly. Read through our beginner guides and understand the concepts of funding rates, leverage, liquidation, and margin before risking real money. Paper trading or using testnet environments (available on dYdX and other platforms) lets you practice without financial risk.

Second, choose your platform. For self-custody and ease of access, a decentralized exchange like Hyperliquid is an excellent starting point. Deposit USDC, and you can be trading within minutes. If you prefer the feature set of a centralized exchange, make sure you understand the custodial risks involved.

Third, start small with low leverage. Use 2x to 3x leverage on major assets like BTC or ETH for your first trades. Set strict stop losses and never risk more than 1-2% of your total capital on a single trade. Use our position calculator to plan every trade before entering.

Fourth, track your performance. Keep a trading journal that records your entries, exits, reasoning, and emotional state. Most beginners who fail do so because they lack discipline, not because they lack knowledge. Reviewing your trades helps identify patterns in your behavior that sabotage results.

Fifth, monitor the broader market context. Our open interest and funding rate tools show you how the rest of the market is positioned. Trading with the crowd is sometimes profitable, but understanding when positioning becomes extreme gives you a significant edge.
