What Are ETH USDT Perpetual Futures?
ETH USDT Perpetual Futures are derivative contracts that allow traders to speculate on the future price of Ethereum (ETH) without an expiration date. These contracts are settled in USDT (Tether), a stablecoin pegged to the US dollar. Unlike traditional futures, perpetual contracts do not have a settlement date, enabling traders to hold positions indefinitely as long as they manage margin requirements.
Key Features of Perpetual ETH Contracts
No Expiry Date
The most defining feature of perpetual contracts is the absence of an expiration date. This allows for greater flexibility in trading strategies, as positions can remain open for as long as desired.
Funding Rate Mechanism
A funding rate is periodically exchanged between long and short traders to ensure the contract's price stays aligned with the underlying spot market price of ETH. This mechanism helps prevent significant price discrepancies between the perpetual contract and the actual asset.
Leverage Trading
Perpetual futures often allow the use of leverage, meaning traders can open positions larger than their initial capital. While this amplifies potential profits, it also significantly increases the risk of losses.
High Liquidity
ETH is one of the most traded cryptocurrencies, and its perpetual futures markets typically enjoy high liquidity. This results in tighter bid-ask spreads and better order execution for traders.
How Do ETH USDT Perpetual Futures Work?
Trading ETH perpetual contracts involves predicting the direction of ETH's price movement. If you believe the price will rise, you open a long position. If you expect it to fall, you open a short position. Your profit or loss is determined by the accuracy of your prediction and the size of your position.
The contract's value is directly pegged to the spot price of ETH through an indexing mechanism. The funding rate, typically paid every 8 hours, acts as a balancing force. When the perpetual contract trades at a premium to the spot price, long positions pay funding to short positions. When it trades at a discount, shorts pay funding to longs.

Essential Concepts for Traders
Initial Margin and Maintenance Margin
The initial margin is the collateral required to open a leveraged position. The maintenance margin is the minimum amount of equity that must be maintained to keep the position open. If your equity falls below this level, you may face liquidation.
Liquidation
Liquidation occurs when a trader's margin balance is insufficient to cover the losses of an open position. The exchange will automatically close the position to prevent further losses that could exceed the trader's capital.
Mark Price
To prevent unfair liquidations due to market manipulation or low liquidity, exchanges use a Mark Price. This is a calculated fair price based on the spot index price and the moving average funding rate, not the last traded price.
Risk Management Funds
Many platforms maintain an insurance fund to cover losses from positions that are liquidated at a worse price than the bankruptcy price, protecting winning traders from automatic deleveraging.

Frequently Asked Questions
What is the main difference between perpetual and quarterly futures?
Perpetual futures have no expiry date and use a funding rate mechanism to track the spot price. Quarterly futures have a set settlement date on a specific quarter-end and converge to the spot price as they near expiration.
How is the funding rate calculated and paid?
The funding rate is typically calculated based on the interest rate differential and the premium of the perpetual contract price over the spot price. It is exchanged between long and short traders at regular intervals, usually every 8 hours.
What happens if I get liquidated?
If your margin balance falls below the maintenance margin requirement, your position will be automatically closed by the exchange's liquidation engine. Any remaining margin from the position will be returned to your account after fees.
Can I trade ETH perpetual futures without leverage?
Yes, you can trade by using 1x leverage, which means your position size is equal to your collateral. This eliminates the risk of liquidation from leverage but still exposes you to the market price movement of ETH.
What are the costs involved in trading?
The primary costs are the taker/maker trading fees and the funding rate. If you hold a position that is required to pay the funding rate, this becomes a periodic cost that affects your overall profitability.
Is it possible to hold a perpetual contract forever?
In theory, yes, as there is no expiry. However, you must continuously maintain the required margin and account for the cumulative cost (or gain) from the funding rate payments over time.
