The cryptocurrency market demands precision, stability, and transparency—especially when it comes to pricing mechanisms that underpin leveraged trading, perpetual contracts, and derivatives. To strengthen market integrity and enhance index reliability, OKX has implemented strategic adjustments to the index compositions of ETH/USD, USDC/USD, and USDC/USDT. These updates aim to improve liquidity, reduce volatility risks, and ensure a more robust pricing framework across all trading products tied to these indices.
This article breaks down the recent changes, explains the index calculation methodology, and provides essential guidance for traders navigating potential market impacts.
Overview of Index Composition Updates
On March 11, 2023 (UTC+8), OKX executed a refinement of its index structure for three key trading pairs: ETH/USD, USDC/USD, and USDC/USDT. The primary goal was to streamline data sources, eliminate redundancy, and increase weighting efficiency by standardizing component allocations across major exchanges.
Key Changes at a Glance
- Equalized Weight Distribution: All active component exchanges now hold a uniform 20% weight in the index calculation—up from the previous 16.70%. This simplifies computation and enhances fairness in price representation.
- Removal of Gemini: The Gemini exchange has been removed from all three index compositions due to evolving data reliability and liquidity benchmarks.
- Consolidated Components: Each index now includes five major exchanges, ensuring sufficient diversity while maintaining responsiveness and accuracy.

These adjustments took effect between 21:30 and 22:00 (UTC+8), with full transparency provided through OKX’s public index price list. The removal of any single component is designed to take effect within 60 minutes, minimizing disruption during transitions.
Why Index Stability Matters for Traders
Index prices are not just reference points—they directly influence mark prices, liquidation thresholds, and margin requirements in leveraged and derivatives trading. An unstable or poorly structured index can lead to:
- Unnecessary liquidations
- Price slippage
- Arbitrage inefficiencies
- Reduced trader confidence
By refining the composition of ETH/USD, USDC/USD, and USDC/USDT indices, OKX reinforces its commitment to fair and resilient markets—especially critical during periods of high volatility.
Core Keywords Driving This Update:
- ETH/USD index
- USDC/USD index
- USDC/USDT index
- index price adjustment
- crypto index stability
- leverage trading risk
- contract market integrity
- exchange weighting model
These keywords reflect both user search intent and the technical depth required for informed trading decisions.
How OKX Calculates Index Prices: A Transparent Framework
Understanding the mechanics behind index pricing empowers traders to anticipate behavior during fast-moving markets. OKX employs a multi-step, rules-based system designed for accuracy and fault tolerance.
Step-by-Step Index Calculation Logic
- Data Aggregation
The system collects real-time trade prices and volumes for relevant trading pairs across all designated exchanges. - Validity Filtering
Exchanges with outdated data (no updates within a defined window) or undergoing maintenance are temporarily excluded from calculations. Currency Conversion
If a trading pair uses a different quote currency (e.g., ETH/USDT instead of ETH/USD), conversion is applied using trusted reference indices:- USDT/USD
- BTC/USD
- BTC/USDT
- USDC/USD
For example, an ETH/USDT price is converted to ETH/USD by multiplying it with the current USDT/USD index value.
Weighted Average Based on Active Exchanges
The final index price depends on how many valid exchanges remain after filtering:
- 5 or more valid exchanges: Equal-weighted average. Any price deviating more than ±3% from the median is capped at 97% or 103% of the median, respectively.
- Only 2 valid exchanges: Simple average of the two prices.
- Only 1 valid exchange: That exchange’s price becomes the index price until others resume.
This adaptive model ensures continuity even during outages while preventing outlier manipulation.
Risk Management Implications for Users
Market adjustments always carry implications—and awareness is the first line of defense.
Potential Market Effects
Due to the index rebalancing:
- Temporary fluctuations in mark prices may occur.
- Maintenance margin rates could increase depending on position type and leverage level.
- Positions near liquidation thresholds may face higher risk during the transition window.

Recommended Risk Mitigation Actions
To safeguard your portfolio, consider taking proactive steps before and during such updates:
- Reduce leverage on open positions
- Add margin to increase buffer against volatility
- Close or trim high-risk positions
- Monitor real-time index data via OKX’s official tools
Staying ahead of structural changes helps maintain control—even when external factors shift beneath the surface.
Frequently Asked Questions (FAQ)
Q: Why was Gemini removed from the index components?
A: Gemini was excluded based on ongoing evaluations of liquidity depth, data consistency, and trading volume relevance. Only exchanges meeting strict performance criteria remain in the index basket.
Q: Does this change affect spot trading?
A: No. These adjustments apply specifically to index pricing used in derivatives and leveraged products, such as perpetual swaps, futures, and margin trading. Spot prices are unaffected.
Q: How often are index compositions reviewed?
A: Index constituents are evaluated regularly—typically quarterly—with adjustments made only when necessary to preserve stability and accuracy.
Q: Can I view the live index data?
A: Yes. Real-time index values are publicly accessible through OKX's market data portal, allowing full transparency into pricing sources and calculations.
Q: What happens if multiple exchanges go offline?
A: The system dynamically adapts. With two or more valid sources, it averages them equally. If only one remains online, that price is used temporarily until others recover.
Q: Will other indices be updated in the future?
A: Yes. OKX continuously monitors all indices for performance and may refine components for other pairs as market conditions evolve.
