Understanding Perpetual Contracts
Perpetual contracts have gained significant popularity among investors due to their flexibility and lack of expiration dates. Unlike traditional futures contracts, perpetual contracts allow traders to hold positions indefinitely, making them a preferred choice in the crypto derivatives market. Among the leading exchanges offering perpetual contracts, OKX stands out with its competitive fee structure and robust trading ecosystem.
OKX Perpetual Contract Fee Structure
Trading Fees
OKX charges fees based on whether an order is a maker (adds liquidity) or a taker (removes liquidity):
- Maker Fee: 0.02%–0.015%
- Taker Fee: 0.05%–0.03%
Funding Fees
Funding fees are exchanged every 12 hours (at 10:00 and 22:00 UTC) to align the contract price with the spot index price. Key details:
- Calculation:
[
\text{Funding Fee} = \text{Face Value} \times \text{Number of Contracts} \times \text{Funding Rate}
] - Funding Rate Formula:
[
\text{Funding Rate} = \text{Clamp}\left(\text{MA}\left(\frac{\text{FutureMid} - \text{Spot Index Price}}{\text{Spot Index Price}} + \text{Interest}\right), -0.25\%, 0.25\%\right)
] - Direction: Positive rates require longs to pay shorts; negative rates reverse the flow.
Key Rules
- Mark Price: Uses a weighted average of the spot index price and basis (difference between futures mid-price and spot index) to prevent market manipulation.
- Auto-Reduction: Implements daily settlement and loss-sharing mechanisms to maintain system balance.
- Index Price: Derived from multiple exchanges’ weighted data to ensure fairness.
Why Funding Fees Matter
Funding fees incentivize traders to balance the market. When perpetual contracts trade at a premium to the spot price, longs pay shorts, encouraging price convergence. This mechanism minimizes arbitrage opportunities and stabilizes prices.
