Introduction to Perpetual Contracts
Perpetual Contracts (Perpetual Futures), abbreviated as PERP, are a unique and widely used investment tool in the cryptocurrency space. For example, Bitcoin Perpetual Contracts are referred to as BTC-PERP.
These contracts allow traders to buy/sell cryptocurrencies at predetermined prices, enabling long (buy) or short (sell) positions.
Funding Rate: The Balancing Mechanism
1. Origin
The funding rate mechanism emerged in crypto derivatives markets, specifically for perpetual contracts, to maintain price alignment between contract and spot prices. It addresses the divergence issue common in traditional futures contracts upon expiration.
2. Rules
- Positive Funding Rate: When contract prices exceed spot prices, long positions pay shorts to incentivize price convergence.
- Negative Funding Rate: When contract prices fall below spot prices, shorts pay longs.
3. Purpose
Funding rates encourage trades that narrow price gaps, enhancing market efficiency.
Key Takeaway:
"Longs pay shorts when profitable, and vice versa, ensuring equilibrium."
Funding Rate Mechanics
1. Calculation
- Formula:
Position Value × Funding Rate - Example: A 20x leveraged 100U long position with a +0.2% rate pays 4U (2000U × 0.2%) to shorts.
2. Settlement Cycles
Typically every 8 hours, though some exchanges settle hourly. Adjustments may occur during extreme market conditions.
3. Forced Liquidation
If position value drops below maintenance margin (e.g., 80U), the trade is liquidated ("margin call").

Leverage & Margin
1. Leverage Guidelines
| Trading Style | Recommended Leverage |
|---------------|----------------------|
| Long-term | 1–5x |
| Mid-term | 1–10x |
| Short-term | 1–20x |
2. Margin Types
- Initial Margin: Collateral required to open a position (e.g., 100U for 10x leverage).
- Maintenance Margin: Additional funds to avoid liquidation.
3. Liquidation Risks
- Example: A 10x long on 100U collapses if the asset drops 10%, wiping out the margin.
Trading Strategies
1. Long/Short Positions
Profit from both rising (long) and falling (short) markets.
2. Hedging
Offset spot holdings with opposing perpetual positions to mitigate losses.
3. Cross-Exchange Arbitrage
Exploit price differences between CME’s regulated contracts and crypto-native exchanges like Binance or OKX.
