Perpetual Contracts 101: Why Do They Have No Expiry Date?

#What Are Perpetual Contracts?

Perpetual contracts are a type of derivative contract with no expiry date. Unlike traditional futures, traders are not forced to close positions or take delivery on a specific date; instead, they can decide when to enter and exit. This design makes holding periods much more flexible.

#Why Do Perpetual Contracts Have No Expiry Date?

Traditional futures contracts usually have a clear delivery or settlement date, after which positions must be closed or settled physically or in cash. Perpetual contracts remove this restriction through a special mechanism: they have no fixed expiry date, and instead use mechanisms such as the funding rate to keep the contract price close to the spot price. As long as traders meet margin requirements, they can hold positions continuously.

#How Leverage Amplifies Both Gains and Risks

Perpetual contracts typically support leveraged trading. Leverage (called multiplier or multiple on some platforms) allows you to control a larger nominal position with less margin. For example, with 10x leverage, a 1% price move causes a 10% change in your profit or loss. Leverage amplifies both potential gains and potential losses, so it must be used with caution. Whether you are long or short, understanding how leverage affects your position is an important part of risk management.

#Going Long and Going Short

In perpetual contracts, going long means buying a contract and hoping the price rises to profit; going short means borrowing an asset to sell it, hoping to buy it back after the price falls. Both are affected by leverage: when you are long and the price falls, you incur losses; when you are short and the price rises, you also incur losses, and in theory short losses can be unlimited. Therefore, you should assess your own risk tolerance before trading.

#When Are Perpetual Contracts Useful?

Perpetual contracts suit traders who want flexible control over entry and exit times without being bound by a fixed delivery date. Whether you are bullish or bearish on the market, you can express your view by going long or short. However, flexible holding periods do not mean no risk: you still need to keep an eye on margin and funding rate changes.

#An Analogy: A Lease with No Fixed Term

You can think of a perpetual contract like a lease agreement with no fixed term: you can decide when to end it, rather than having to move out on a specific date. But to maintain this flexibility, you need to continuously pay funding fees (the funding rate) and meet margin requirements, otherwise you may be forcibly liquidated.

#Risk Management Tips

Perpetual contracts are high-risk derivatives. Leverage amplifies gains and losses, and price fluctuations may lead to insufficient margin and forced liquidation. Beginners should first use small amounts to learn the mechanics, avoid excessive leverage, and set risk controls such as stop-losses. This article is not investment advice.

#FAQ

#What is the difference between perpetual contracts and traditional futures?

Perpetual contracts have no expiry date and can be held long term; traditional futures have a fixed delivery date and must be closed or settled at expiry. Perpetual contracts anchor to the spot price through the funding rate.

#Is higher leverage always better?

No. The higher the leverage, the more a small price move is amplified in your profit and loss, and the greater the liquidation risk. Beginners should start with low leverage and manage position size and margin carefully.

#What are the risks of shorting perpetual contracts?

Shorting aims to profit from falling prices, but if the price rises, losses will expand, and in theory there is no upper limit. Traders should set stop-losses and control leverage to avoid forced liquidation in extreme market moves.

#Do I have to pay fees to hold a perpetual contract?

Usually yes. Holding a perpetual contract may incur a funding rate, with longs and shorts periodically exchanging fees to keep the contract price close to the spot price. The specific rate is determined by market forces on both sides.

#Are perpetual contracts suitable for beginners?

Perpetual contracts are high-risk derivatives. Beginners should first learn about leverage and liquidation mechanics through simulated trading or small positions, and only participate after understanding the risks. Using high leverage right away is not recommended.
