CoinEx Linear Futures Contracts Trading Rules

An Introduction to Linear Futures Contracts

Linear Futures Contract, also known as U-margined Futures Contract, allows you to long buy or short sell cryptos and earn profits based on price predictions. The Linear Futures Contract does not have an expiry or settlement date, and you can choose to close or keep the position according to the market conditions.

Type Remarks
Fair Price Linear Contract adopts Fair Price Marking that determines the unrealized profit or loss and liquidation of the position.
Initial Margin The minimum amount of margin for opening the position.
Maintenance Margin The minimum amount of margin is required to keep your position open. The requirements of maintenance margin are tied to the Risk Limits.
Funding Rate The funding rate mechanism helps keep futures prices aligned with spot prices. Normally, funding fees are exchanged between long and short traders every 8 hours at 0:00, 8:00, and 16:00 UTC. When the rate is positive, long traders pay the fees while short traders receive them. If the rate becomes too high, we may dynamically adjust the settlement cycle to 4 hours or 2 hours.

Contract Leverage

CoinEx futures contract employs several adjustable leverages ranging from 3X to 100X.

Cross Margin The full amount of funds in the available balance will be utilized as a margin on your position. When the initial margin is less than the maintenance margin, any available balance will be used to add margin to your position.
Isolated Margin Any of your available balance will not be used to increase the margin when a position is liquidated. By isolating and using different margins for each position, you can limit losses on that position to the initial margin amount when your short-term speculative trading strategy fails.
Index Price

Index Price is determined by the weighted prices from a selection of mainstream crypto exchanges. The crypto exchange and weight of different contract index prices may be different, and you can click here to view the index price in Contract Info.


Trading Rules

Type Remarks
Trading Hours 24/7 Round the clock, no limitation on the settlement date.
Order Type Short Sell, Long Buy, Long Sell Close, and Short Close.
Buy Long Buy and Sell: Assuming that the market price will increase in the future, the trader can buy a certain number of contracts, and sell (or close the position) to earn the difference when the market price rises again.
Sell Short Buy and Sell: Assuming that the market price will fall in the future, the trader can sell a certain number of contracts, and buy (or close the position) to earn the difference when the market price falls again.
Liquidation Mechanism Partial liquidation, insurance funding, and auto-deleveraging are adopted in the case of forced liquidation.


Only one position is available for one contract market at the same time: Assuming you have successfully opened a short position, you cannot open a long position simultaneously. Any long position will reduce your current short position. On one hand, your current short positions will become long position when the number of long contracts exceeds the short position. On the other hand, your current short positions will increase when you sell short. In this case, you can’t long and short the same contract.
