OKX categorizes users into regular and professional tiers based on trading volume. Regular users are further classified by their OKB holdings, while professional users are segmented by trading volume. These tiers determine the trading fees for the next 24 hours, with separate rates for maker (pending orders) and taker (immediate orders).
1. Fee Calculation Formulas
Tier 1 Example:
- Taker fee: 0.05%
- Maker fee: 0.02%
Coin-Margined Contracts
- Opening Fee = (Contract Face Value × Number of Contracts / Entry Price) × Fee Rate
- Closing Fee = (Contract Face Value × Number of Contracts / Exit Price) × Fee Rate
Example: Opening 100 BTC contracts at $10,000 as a taker: (100 × 100 / 10,000) × 0.0005 = 0.0005 BTC
USDT-Margined Contracts
- Opening Fee = (Contract Face Value × Number of Contracts × Entry Price) × Fee Rate
- Closing Fee = (Contract Face Value × Number of Contracts × Exit Price) × Fee Rate
Example: Opening 100 BTC contracts at $10,000 as a taker: (100 × 0.01 × 10,000) × 0.0005 = 5 USDT
2. Fee Rate Structure
Perpetual Contracts (Major Cryptos)
