With the rising popularity of contract trading in the digital currency market, understanding fee structures is essential. Below is a detailed breakdown of OKX contract fees.

How Are OKX Contract Fees Calculated?

OKX perpetual contract fees typically range as follows:

Maker Fee: 0.02%–0.015%
Taker Fee: 0.05%–0.03%

Funding Fees are charged every 12 hours at 10:00 and 22:00 (UTC+8) after contract settlement. Users only pay or receive funding fees if they hold positions at these times.

Funding Fee Calculation:

Funding Fee (USD) = Face Value × Contract Quantity × Funding Rate

A positive funding rate means long positions pay short positions.
A negative funding rate means short positions pay long positions.

Funding Rate Formula:

Funding Rate = Clamp(MA((Futures Mid Price − Spot Index Price) / Spot Index Price + Interest), −0.25%, 0.25%)

Realized P&L:

Buy Direction:
```
Realized P&L = (Face Value / Settlement Price − Face Value / Avg. Close Price) × Closed Quantity
```
Example: Buying 2 BTC contracts at 500 USD/BTC and selling 1 at 1000 USD/BTC yields 0.1 BTC profit.
Sell Direction:
```
Realized P&L = (Face Value / Avg. Close Price − Face Value / Settlement Price) × Closed Quantity
```
Example: Selling 10 BTC contracts at 500 USD/BTC and buying back 8 at 1000 USD/BTC results in −0.8 BTC loss.

Unrealized P&L:

Buy Positions:
```
Unrealized P&L = (Contract Value / Settlement Price − Contract Value / Mark Price) × Open Quantity
```
Example: 6 BTC contracts bought at 500 USD/BTC with a current price of 600 USD/BTC show 0.2 BTC profit.

Sell Positions:

Unrealized P&L = (Contract Value / Mark Price − Contract Value / Settlement Price) × Open Quantity
