How Perpetual Futures Contract Works
Frequently Asked Questions
What is a perpetual futures contract in simple terms?
A perpetual futures contract is a way to bet on whether a crypto asset's price will rise or fall without actually owning it — and without any expiry date forcing you to close your trade. You can hold the position as long as you want, as long as you maintain sufficient margin. To keep the perpetual price close to the real spot price, traders on the dominant side pay a fee called the funding rate every eight hours. If more people are betting on a price rise, longs pay shorts; if more are betting on a fall, shorts pay longs.
How does a perpetual futures contract work in crypto markets?
A perpetual futures contract works by letting traders take leveraged long or short positions on a crypto asset, with a funding rate mechanism that replaces the expiry-date convergence used in traditional futures. Every eight hours, the exchange calculates whether the perpetual is trading above or below the spot index price. If above (positive funding), longs pay shorts to compensate for the premium and incentivise short selling. If below (negative funding), shorts pay longs. This continuous pressure keeps the perpetual price anchored near spot without requiring a fixed settlement date.
How do traders use perpetual futures contracts to make better decisions?
Traders use perpetual futures data to read market positioning rather than just price. Key signals include: (1) Funding rate — high positive rates signal crowded longs and elevated fragility; (2) Open interest — rising OI with rising price confirms new capital entering; falling OI with rising price suggests weak short covering; (3) Long/short ratio — extreme readings are contrarian signals, not trend confirmations; (4) Liquidation skew — clusters of positions at specific levels reveal mechanical pressure points. CryptoMantiq's Strategist synthesises all four signals through the DPF framework to produce a coherent positioning narrative before suggesting a trading context.
Common Misconceptions About Perpetual Futures Contract
Perpetual futures are essentially the same as spot trading with leverage
Perpetual futures carry a running funding cost that spot margin trading does not have in the same form. When annualised funding is at 60%, a long position loses approximately 60% of its notional value per year purely from funding payments, before any price movement is considered. This cost compounds and must be factored into any holding-period calculation. Spot trading with leverage involves borrowing costs, but the perpetual funding mechanism creates a different and often more volatile cost structure tied directly to market crowding.
Because perpetuals have no expiry, traders can hold them indefinitely without consequences
While there is no expiry forcing closure, holding a perpetual has two ongoing costs that constrain indefinite holding: funding payments and margin requirements. During periods of elevated funding (annualised rates above 30-50%), the cost of maintaining a position can erode returns significantly. Additionally, adverse price moves reduce margin — and if margin falls below the maintenance threshold, the exchange liquidates the position automatically regardless of the trader's intent. Perpetuals require active margin management, especially with leverage.
The perpetual futures price is always the same as the spot price
The perpetual futures price oscillates around the spot index price — it is not identical to it. The basis (futures minus spot) can be positive or negative depending on the balance of demand between leveraged buyers and sellers. The funding mechanism creates economic pressure to reduce large divergences, but significant basis differences can persist for extended periods during strong directional moves. The mark price (used for liquidations) incorporates a smoothed basis adjustment, which is why the liquidation price differs from both the last-traded and the spot price.
