What Are Perpetual Futures?

Perpetual futures are a type of crypto derivative that functions similarly to traditional futures contracts—agreements to buy or sell an asset at a predetermined price at a future date—but with one crucial difference: they have no expiration date. This allows traders to hold positions indefinitely, as long as margin requirements are met.

Unlike standard futures that settle on a set date, perpetuals are designed to track the spot price of the underlying asset closely. They achieve this through a mechanism called funding rates, which periodically exchange payments between long and short traders to keep contract prices aligned with the index.

Because perpetual futures operate on margin, traders can control large positions with relatively small amounts of capital. While this amplifies potential gains, it also increases risk—particularly the risk of liquidation if the market moves against an undercollateralized position.

Key Features of Phemex Perpetual Futures

Phemex supports two primary types of perpetual futures contracts:

Each type serves different trading strategies and risk profiles, and understanding their mechanics is essential for effective trading.

BTC-Based Perpetual Futures

In BTC-based contracts, each contract represents a fixed dollar value of Bitcoin—specifically $1 worth of BTC. The actual BTC quantity fluctuates inversely with the Bitcoin price.

For example:

Profit and loss (P&L) are calculated in BTC, not USD. This introduces nonlinearity because changes in BTC price affect both the contract value and the settlement asset.

P&L Formula (BTC-based):

This structure benefits traders who want exposure to Bitcoin’s price movements while settling in BTC—ideal for long-term holders or those avoiding fiat conversions.

USD-Based Perpetual Futures

USD-based contracts settle in stablecoins or USD equivalents and represent a fixed quantity of the underlying asset.

Examples:

P&L is calculated directly in USD:

This results in linear payoff, meaning each price increment translates to a consistent dollar gain or loss. It's simpler to understand and preferred by traders focused on dollar-denominated returns.

How to Start Trading Perpetual Futures on Phemex

Getting started with futures trading on Phemex involves a few straightforward steps—but preparation is key to managing risk effectively.

Step 1: Fund Your Futures Account

Before placing any trades, you must transfer funds from your spot wallet to the appropriate futures trading account.

There are two separate futures accounts:

Since Phemex does not support direct USD deposits, you’ll need to convert your assets into USDT (or another supported stablecoin) within your spot wallet first.

Step 2: Choose Your Contract Type

Decide whether you want to trade:

Navigate to the futures section, select your preferred pair (e.g., BTC/USD, ETH/USD), and choose the contract type accordingly.

Step 3: Set Leverage and Place Orders

Phemex allows adjustable leverage—often up to 100x depending on the contract. Higher leverage increases both profit potential and liquidation risk.

Frequently Asked Questions (FAQ)

Q: What happens when my position gets liquidated?
A: Liquidation occurs when your margin falls below the required maintenance level due to adverse price movement. The system automatically closes your position to prevent further losses. You lose your initial margin, so proper risk management is critical.

Q: How are funding rates calculated on Phemex?
A: Funding rates are exchanged every 8 hours between long and short traders. If rates are positive, longs pay shorts; if negative, shorts pay longs. This mechanism keeps perpetual contract prices close to the underlying index price.

Q: Can I trade perpetual futures with USDT?
A: Yes—but only in the USD-margined futures account. You can deposit USDT to open and maintain positions in USD-based contracts like BTC/USDT or ETH/USDT.

Q: Is there a difference between spot and futures trading?
A: Absolutely. Spot trading involves buying actual assets at current prices. Futures trading involves contracts that derive value from an underlying asset and allow leverage, hedging, and short-selling—without owning the asset itself.

Q: Why use BTC-margined contracts instead of USD-margined ones?
A: BTC-margined contracts are ideal if you already hold Bitcoin and want to avoid converting to stablecoins. They also offer unique P&L dynamics that can benefit experienced traders during high-volatility periods.
