As part of its ongoing commitment to delivering superior trading experiences, OKX will adjust the fee calculation parameters for options trading starting May 15, 2025, at 3:00 PM (UTC+8). These changes are designed to reduce trading costs, improve market efficiency, and support both new and experienced traders in managing their options strategies more effectively.
This update impacts three core aspects of options trading on the platform: trading fees, exercise fees, and liquidation fees. The revised structure introduces a lower percentage cap on fee calculations, making high-volume and large-position trading more cost-efficient.
Key Changes to Options Fee Structure
1. Trading Fee Adjustment
Previously, the trading fee was calculated as the minimum between two values:
- A standard rate based on the fee tier:
fee rate × contract multiplier × contract value × number of contracts - A cap tied to the option premium:
12.5% × option premium × contract multiplier × contract value × number of contracts
After the update, the cap will be significantly reduced:
Min (fee rate × contract multiplier × contract value × number of contracts, 7% × option premium × contract multiplier × contract value × number of contracts)

This means traders will now pay less in fees when the option premium is high, especially during periods of elevated volatility or near expiration dates. The change benefits active traders who frequently enter and exit positions by reducing frictional costs.
2. Exercise Fee Optimization
The exercise fee applies only to options that have been exercised, not all open positions. It ensures fair cost distribution across users who trigger settlement processes.
Before the update, the exercise fee was determined by:
0.02% × contract multiplier × contract value × number of contracts- Or the taker fee rate applied to the same base
- Or capped at
12.5% × settlement price × contract multiplier × contract value × number of contracts
Starting May 15, 2025:
Min (0.02% × contract multiplier × contract value × number of contracts, taker fee rate × contract multiplier × contract value × number of contracts, 7% × settlement price × contract multiplier × contract value × number of contracts)
Additionally:
- Intraday options (those expiring on any day except Friday) will continue to have no exercise fee
- This rule remains unchanged to encourage short-term trading flexibility
This reduction lowers the cost barrier for traders looking to exercise deep-in-the-money options, improving net returns upon settlement.
3. Liquidation Fee Reduction
For positions that are forcibly closed due to insufficient margin, the liquidation fee helps maintain system stability and discourages excessive leverage.
Previously calculated as:
- Min (taker fee tier × contract multiplier × number of contracts,
12.5% × mark price × contract multiplier × contract value × number of contracts)
The updated formula reduces the cap:
Min (taker fee tier × contract multiplier × number of contracts, 7% × mark price × contract multiplier × contract value × number of contracts)
This adjustment makes liquidations less costly for users while still preserving risk management integrity. It particularly benefits traders using leveraged strategies in volatile markets.
Why This Update Matters for Traders
These adjustments reflect OKX’s focus on user-centric innovation and cost efficiency in derivatives trading. By lowering the percentage caps across all three fee types—from 12.5% down to just 7%—the platform enables:
- Lower friction in high-frequency trading
- Improved profitability for exercised options
- Reduced losses during forced liquidations
- Greater predictability in cost modeling
Whether you're an institutional trader managing large portfolios or a retail investor exploring options for hedging or speculation, these updates enhance your ability to trade with precision and control.
