Perpetual contracts have become one of the most popular instruments in the cryptocurrency derivatives market. Unlike traditional futures, they don’t expire, allowing traders to hold positions indefinitely. Central to their functionality is the funding rate—a unique mechanism designed to align the price of perpetual contracts with the underlying asset’s spot price. This article explores how perpetual contracts work, the role of funding rates, and practical trading strategies—all while maintaining clarity for both beginners and experienced traders.
What Are Perpetual Contracts?
Perpetual contracts, often abbreviated as PERP, are derivative financial instruments that allow traders to speculate on the future price of an asset—most commonly cryptocurrencies like Bitcoin or Ethereum—without owning the actual asset.
The key feature of a perpetual contract is that it has no expiration date, unlike traditional futures. This allows traders to hold long or short positions for as long as they choose, provided they can meet margin requirements and funding costs.

Traders use perpetual contracts to:
- Go long (buy) if they expect the price to rise
- Go short (sell) if they anticipate a decline
These contracts are typically settled in stablecoins like USDT, making them accessible and less volatile for trading purposes.
Understanding Funding Rates
The Purpose of Funding Rates
Funding rates exist to keep the price of perpetual contracts closely aligned with the spot market. Without this mechanism, contract prices could diverge significantly from real-world values due to speculative pressure.
For example:
- If too many traders go long, the contract price may rise above the spot price (a condition known as contango).
- If too many go short, the contract price may fall below spot (called backwardation).
To correct these imbalances, the funding rate transfers funds between long and short positions.
How Funding Rates Work
The funding rate is exchanged periodically—usually every 8 hours, though some exchanges do so hourly—between holders of long and short positions.
Here’s how it works:
- Positive funding rate: When the contract price is above spot price, longs pay shorts.
- Negative funding rate: When the contract price is below spot price, shorts pay longs.
This incentivizes traders to step in and bring prices back into alignment. For instance, high positive funding discourages new long positions and attracts arbitrageurs who short the contract and buy spot, profiting from the rate.
Funding Rate Calculation
The amount paid or received depends on:
- Position size (notional value)
- Current funding rate
Formula: Funding Payment = Position Value × Funding Rate
For example:
- A trader holds a $2,000 long position.
- Funding rate is +0.03%.
- They will pay: $2,000 × 0.0003 = **$0.60** to short holders at the next settlement.
While individual payments seem small, they accumulate over time—especially for leveraged positions.
Frequently Asked Questions
Q: Do I pay funding fees even if I close my position before settlement?
A: No. Funding is only exchanged at scheduled intervals. If you exit before the next funding timestamp, you avoid that cycle’s payment.
Q: Can funding rates predict market direction?
A: Extremely high positive rates may indicate excessive bullishness—a potential reversal signal. Conversely, very negative rates might suggest oversold conditions.
Q: Are funding rates the same across all exchanges?
A: No. Rates vary by platform due to differences in liquidity, user behavior, and calculation methods. Arbitrage opportunities sometimes arise from these discrepancies.
Leverage and Margin in Perpetual Contracts
Leverage allows traders to control large positions with relatively small capital. However, it amplifies both gains and losses.
Types of Margin
- Initial Margin: The collateral required to open a position. For example, opening a $1,000 position at 10x leverage requires $100 in margin.
- Maintenance Margin: The minimum equity needed to keep a position open. Falling below this triggers liquidation.
- Margin Call: When equity drops near maintenance level, traders can add more funds (maintain margin) to avoid forced closure.
Recommended Leverage Levels
| Trading Style | Suggested Leverage |
|---|---|
| Long-term | 1–5x |
| Medium-term | 1–10x |
| Short-term | 1–20x |
Higher leverage increases exposure to liquidation risk—especially during volatility spikes or sustained funding costs.
Stop-Loss and Take-Profit
Setting stop-loss (SL) and take-profit (TP) orders is essential:
- Stop-loss: Automatically closes a losing trade at a predefined level.
- Take-profit: Locks in gains when price reaches a target.
Without these safeguards, unexpected moves or prolonged funding drains can wipe out accounts.

Trading Strategies Using Perpetual Contracts
1. Going Long or Short
The core function of perpetual contracts: profit from rising or falling prices without owning assets.
2. Leveraged Trading
Use leverage to amplify returns—but beware: losses scale just as fast. Always assess risk/reward ratios before entering.
3. Hedging with Perpetuals
Holders of physical crypto can hedge against downside risk by opening opposite perpetual positions.
Example: If you own BTC but fear a drop, open a short PERP position to offset potential losses.
4. Basis Arbitrage (Cash-and-Carry)
When funding rates are consistently positive, traders can:
- Buy spot BTC
- Short BTC-PERP
- Earn regular payments from longs via funding
This strategy works best in strong bull markets with elevated sentiment.
5. Cross-Exchange and CME Arbitrage
Sophisticated traders exploit pricing differences between:
- Major crypto exchanges (e.g., Binance vs OKX)
- Regulated futures markets like CME
CME Bitcoin futures act as a regulated benchmark. When CME futures trade at a premium (high basis), traders may:
- Sell CME futures
- Buy spot or perpetuals elsewhere
- Profit as prices converge

Tools for Perpetual Traders
Advanced charting platforms like TradingView provide real-time data on:
- Order book depth
- Funding rates
- Open interest
- CME basis spreads (search

Platforms such as Exocharts offer deep insights into order flow and market structure—but often require paid subscriptions.
Beware of Grid Bots and Automated Systems
Many exchanges promote "contract grid bots" as hands-free profit machines. In reality, these systems often result in net losses due to:
- Hidden transaction fees
- Adverse selection during volatile swings
- Ongoing funding rate drains
They work best in stable, range-bound markets—but fail catastrophically in trends or news-driven moves.
Instead of relying on black-box algorithms, focus on building your own understanding of market dynamics, risk control, and execution discipline.
