Understanding OKX Perpetual Contracts
For traders looking to leverage price movements without owning the underlying asset, OKX perpetual contracts offer a flexible solution.
What Are Perpetual Contracts?
Perpetual contracts are derivative instruments that mimic spot prices but allow traders to go long (buy) or short (sell) with leverage—up to 125x on major pairs like BTC/USD.
Unlike traditional futures, they have no expiration date, meaning positions can be held indefinitely as long as margin requirements are met.
Key Features of OKX Perpetual Contracts
🔹 No Expiry Date
Traders can maintain open positions for as long as they choose—ideal for long-term strategies.
🔹 Funding Rate Mechanism
To keep contract prices aligned with the spot market, OKX uses a funding rate system. Every 8 hours, traders either pay or receive funding based on market conditions:
- Longs pay shorts when the market is bullish.
- Shorts pay longs during bearish trends.
This mechanism prevents significant price divergence.
🔹 Mark Price for Accurate PnL Calculation
OKX uses a mark price—derived from major exchange indices—to calculate unrealized profits and losses. This reduces the risk of unfair liquidations during sudden volatility.
🔹 Daily Settlement
At 16:00 Hong Kong time, unrealized PnL is settled daily and converted into realized gains or losses, improving capital efficiency.
🔹 Tiered Maintenance Margin System
Larger positions require higher maintenance margins. As your position size increases:
- Your required margin rate goes up.
- Maximum allowable leverage decreases.
This tiered structure enhances risk control across large portfolios.
🔹 Partial Liquidation (Auto-Deleveraging)
For large positions (Tier 3+), if margin falls below critical levels but remains above minimum thresholds, OKX triggers partial forced liquidation instead of closing the entire position.
The system reduces your position by two tiers incrementally until stability is restored—helping preserve capital during sharp moves.
How Are Perpetual Contract Fees Calculated?
Trading fees on OKX are transparent and competitive.
Fee Structure:
- Maker Fee: Typically 0.02%
- Taker Fee: Typically 0.05%
Fees may vary slightly depending on your VIP level or promotional campaigns.
Realized PnL Formulas:
For Long Positions:
Realized PnL = (Contract Value / Entry Price – Contract Value / Exit Price) × Number of Contracts
Example: You open 2 BTC perpetual contracts at $50,000 and close 1 at $100,000:
= (100 / 50,000 – 100 / 100,000) × 1 = 0.001 BTC profit
For Short Positions:
Realized PnL = (Contract Value / Exit Price – Contract Value / Entry Price) × Number of Contracts
Example: You short 10 contracts at $50,000 and cover 8 at $25,000:
= (100 / 25,000 – 100 / 50,000) × 8 = 0.016 BTC profit
These calculations help you track performance accurately over time.
