STX/USD and STX/USDT Index Composition Adjustment Announcement

The cryptocurrency market thrives on stability, transparency, and real-time accuracy—especially when it comes to index pricing that underpins leveraged products, perpetual contracts, and futures markets. To enhance market liquidity and index reliability, OKX is adjusting the composition of the STX/USD and STX/USDT indices. This update ensures more robust price discovery and reduces potential volatility caused by imbalanced or outdated data sources.

These changes are scheduled to take effect between March 22, 2023, 15:00 – 17:00 (UTC+8). Below is a detailed breakdown of what’s changing, why it matters, and how users can prepare.

🔍 Why Index Composition Matters

Index prices serve as the backbone for derivative trading. They determine mark prices, prevent manipulation, and ensure fair liquidation mechanisms across leveraged and futures markets. An unstable or poorly diversified index can lead to:

• Sudden price deviations
• Unfair liquidations
• Reduced market confidence

To mitigate these risks, OKX continuously evaluates its index methodology, ensuring it reflects genuine market conditions across multiple trusted exchanges.

🔄 Index Adjustment Overview

The upcoming update focuses on replacing Coinbase with Kraken in both the STX/USD and STX/USDT index compositions. All other components remain unchanged.

✅ STX/USD Index Update

✅ STX/USDT Index Update

🔁 Note: The removal of Coinbase and addition of Kraken will be effective within 60 minutes of the maintenance window.

🧠 How the Index is Calculated

OKX employs a dynamic, multi-layered algorithm to calculate index prices in real time. Here's how it works:

1. Real-Time Data Collection
   The system pulls the latest trade price and volume for STX pairs from all designated component exchanges.
2. Exchange Validation
   If an exchange’s data fails to update within a defined timeframe—or if the exchange is undergoing maintenance—it is temporarily marked as invalid and excluded from calculations.

3. Currency Conversion
   When a trading pair uses a different quote currency than the index (e.g., using USDT in a USD-denominated index), conversion is applied using trusted reference indices:

   • BTC/USDT
   • BTC/USD
   • USDC/USD
   • USDT/USD

   For example, if an exchange reports STX/USDT, that value is multiplied by the current USDT/USD index to convert it into a USD-equivalent price for inclusion in the STX/USD index.

4. Weighted Price Aggregation
   Validated prices are combined using equal weighting, with safeguards against outliers:

   • 3 or more valid exchanges: Prices are averaged equally. Any price deviating more than ±3% from the median is capped at 97% or 103% of the median.
   • Only 2 valid exchanges: Simple average of both prices.
   • Only 1 valid exchange: That single price becomes the index price.

This methodology ensures resilience against flash crashes, stale data, or isolated market anomalies.

⚠️ Risk Notice for Traders

Market volatility may increase during the transition period.

Due to potential short-term fluctuations in index values during the adjustment window, traders should be aware of the following:

• Mark price shifts: The change in index composition could cause temporary jumps in the mark price for STX perpetual and futures contracts.
• Higher maintenance margin requirements: As the index stabilizes, your position’s required margin may increase.
• Liquidation risk: Unadjusted leveraged positions may face higher liquidation risk if margin buffers are insufficient.

❓ Frequently Asked Questions (FAQ)

Q1: Why is Kraken replacing Coinbase in the index?

Kraken demonstrates stronger liquidity and more consistent pricing for STX pairs. This switch improves data reliability and reduces dependency on any single source.

Q2: Will this affect spot trading?

No. This change only impacts derivative products that rely on the STX/USD and STX/USDT indices—such as perpetual swaps and futures contracts. Spot trading remains unaffected.

Q3: How quickly will the new index take effect?

The transition will begin during the maintenance window and complete within 60 minutes. Updates are applied gradually to minimize disruption.

Q4: Can I still trade during the adjustment?

Yes. Trading remains live throughout the process. However, traders are advised to monitor their positions closely due to possible mark price volatility.

Q5: What happens if one exchange goes offline?

The system automatically excludes inactive exchanges. As long as at least one valid price source remains, the index continues functioning using fallback logic.

Q6: How often are index components reviewed?

Index constituents are evaluated regularly based on liquidity, uptime, data accuracy, and market relevance. Adjustments are made proactively to maintain integrity.

💡 Best Practices for Users

To safeguard your positions during this update:

• Reduce leverage temporarily to increase margin headroom.
• Monitor mark prices closely, especially if holding large or long-term positions.
• Set stop-losses wisely, accounting for potential short-term spikes.
• Add margin proactively to avoid unexpected liquidations.
