Understanding Perpetual Contracts on Binance Futures

Perpetual contracts are a type of derivative product offered on Binance Futures that allow traders to speculate on the price movements of cryptocurrencies without owning the underlying asset. Unlike traditional futures contracts, which have a set expiration date, perpetual contracts do not expire, enabling traders to hold positions indefinitely. This makes them highly flexible for both short-term and long-term trading strategies. These contracts are typically denominated in USDT (Tether) or coin-margined, meaning the collateral is held in either a stablecoin or the base cryptocurrency such as BTC or ETH.

Binance Futures supports two types of perpetual contracts: USDT-margined and coin-margined. USDT-margined contracts are settled in USDT and offer simplicity for traders who prefer stablecoin-based accounting. Coin-margined contracts, on the other hand, use the base cryptocurrency as collateral and are settled in that asset. For example, a BTCUSD perpetual contract margined in BTC would require BTC as collateral and payouts would be in BTC.

How Funding Rates Work in Perpetual Contracts

Since perpetual contracts lack an expiration date, a mechanism is needed to align the contract price with the spot market price. This is achieved through funding rates, which are periodic payments exchanged between long and short position holders. The funding rate is calculated based on the difference between the perpetual contract price and the underlying index price.

• If the funding rate is positive, long position holders pay short position holders.
• If the funding rate is negative, short position holders pay long position holders.

Funding occurs every eight hours on Binance Futures, specifically at 00:00 UTC, 08:00 UTC, and 16:00 UTC. The rate is determined by the formula:
Funding Payment = Nominal Value of Position × Funding Rate

Traders can monitor the upcoming funding rate in the Binance Futures interface under the contract details. It is critical to account for funding costs when holding positions for extended periods, as frequent or high funding rates can erode profits or increase losses.

Leverage and Margin Management

One of the key features of Binance Futures perpetual contracts is the ability to use leverage, allowing traders to control larger positions with a smaller amount of capital. Binance offers adjustable leverage, typically ranging from 1x to 125x, depending on the contract and margin mode.

When opening a position, traders must allocate initial margin, which is a percentage of the total position value. The system also requires maintenance margin, a minimum amount needed to keep the position open. If the equity in the margin wallet falls below the maintenance margin level due to adverse price movements, a liquidation occurs.

• Select the desired leverage using the leverage slider on the trading interface.
• Choose between cross margin and isolated margin modes.
  • In cross margin, all available balance in the margin wallet can be used to prevent liquidation.
  • In isolated margin, only the allocated margin is at risk, limiting both potential loss and profit.

It is essential to monitor liquidation price, which is displayed in real time. Adjusting leverage or adding more margin can move the liquidation price further from the current market price, reducing risk.

How to Open a Perpetual Contract Position on Binance

Opening a perpetual contract on Binance Futures involves several precise steps. Ensure your Binance account is verified and has sufficient funds in the Futures wallet.

• Navigate to the Binance Futures section via the main website or app.
• Choose between USDT-margined or coin-margined markets based on your preference.
• Select the specific perpetual contract, such as BTC/USDT.
• Set the order type: limit, market, stop-limit, or others.
• Choose leverage using the leverage control (e.g., 10x).
• Decide between cross or isolated margin mode.
• Enter the contract quantity or desired USDT/BTC value.
• Click Buy/Long to open a long position or Sell/Short to open a short position.

After submission, the position appears in the Positions tab. Real-time P&L, margin ratio, and liquidation price are displayed here. Traders can close the position manually by clicking Close or setting a take-profit/stop-loss order.

Risks and Considerations in Perpetual Trading

While perpetual contracts offer high profit potential, they come with significant risks. High leverage amplifies both gains and losses, and a small adverse price move can trigger liquidation. Traders must understand the mark price, which is used to calculate liquidations and is derived from external price feeds to prevent manipulation.

• The mark price differs from the last traded price and protects against unfair liquidations.
• Insurance funds are maintained by Binance to cover losses from liquidated positions, reducing the chance of socialized losses.
• Auto-deleveraging may occur in extreme market conditions, where profitable counterparties are forcibly closed to cover losses from unprofitable ones.

Volatility in crypto markets can lead to rapid price swings, especially during news events or macroeconomic shifts. Traders should use stop-loss orders and avoid over-leveraging to manage exposure effectively.

Frequently Asked Questions

What is the difference between USDT-margined and coin-margined perpetual contracts?

USDT-margined contracts use Tether (USDT) as collateral and are settled in USDT, making P&L calculations stable and straightforward. Coin-margined contracts use the base cryptocurrency (e.g., BTC) as collateral and are settled in that asset, exposing traders to price fluctuations of the collateral itself.

How often is funding paid on Binance perpetual contracts?

Funding payments occur every eight hours at 00:00 UTC, 08:00 UTC, and 16:00 UTC. The exact rate is determined by market conditions and is displayed in the contract details before the payment time.

Can I change leverage after opening a position?

Yes, you can adjust leverage at any time before liquidation. Navigate to the Positions tab, find your open position, and click the leverage adjustment button. Reducing leverage increases the margin ratio and moves the liquidation price further from the current market price.

What happens if my position gets liquidated?

Upon liquidation, the position is automatically closed by the system at the prevailing market price. Any remaining margin after covering losses is returned to your Futures wallet. If the liquidation cannot be fully covered, Binance uses its insurance fund to absorb the deficit.
