OKX Adjusts Components of STX/USD and STX/USDT Indices

·

Cryptocurrency markets thrive on transparency, accuracy, and real-time data integrity—especially when it comes to index pricing that influences derivatives trading and margin positions. On March 22, 2023, OKX announced strategic adjustments to the underlying components of the STX/USD and STX/USDT indices, aiming to enhance market liquidity, data reliability, and overall index stability.

These changes were implemented between 07:00–09:00 UTC, ensuring minimal disruption while optimizing the index calculation framework for traders and investors relying on accurate reference prices.

Why Index Composition Matters

Index values serve as critical benchmarks in crypto derivatives trading. They determine mark prices for futures and perpetual swaps, help prevent unfair liquidations, and support fair valuation across leveraged products. When an index is built from unreliable or illiquid exchanges, it risks reflecting inaccurate market conditions—potentially leading to slippage, mispricing, or unnecessary margin calls.

To maintain trust and precision, OKX regularly evaluates the exchanges and trading pairs used in its index calculations. The goal is to ensure that each component contributes meaningful volume, tight spreads, and real-time price discovery.

Updated Index Components

The adjustment focused on replacing Coinbase’s STX/USD pair with Kraken’s STX/USD pair in both the STX/USD and STX/USDT indices. All other components remained unchanged.

Here's a breakdown of the updated structure:

STX/USD Index (Post-Adjustment)

STX/USDT Index (Post-Adjustment)

This strategic swap reflects Kraken’s growing liquidity and consistent trading volume in the STX market, especially during volatile periods. By integrating Kraken into the index basket, OKX strengthens the robustness of price feeds and reduces dependency on any single exchange.

How Index Prices Are Calculated

OKX employs a dynamic, multi-tiered methodology to calculate index prices, prioritizing data validity and market representativeness. The system adapts based on how many exchanges provide reliable data at any given moment.

Real-Time Data Collection

Each component’s latest price and trading volume are pulled in real time from selected exchanges. These inputs feed into the index engine only if they meet strict validity criteria.

Data Validity Rules

Price Conversion Logic

When a constituent pair doesn’t match the base quote currency of the index (e.g., using USDT to derive a USD index), conversion occurs using stablecoin or fiat reference rates such as:

For example, to convert STX/USDT into STX/USD, the current USDT/USD rate is applied multiplicatively to align the value appropriately.

Adaptive Index Calculation Model

The final index value depends on the number of exchanges providing valid data at the time of calculation. OKX uses a tiered approach:

Scenario 1: More Than 3 Valid Exchanges

Scenario 2: Exactly 2 Valid Exchanges

Scenario 3: Only 1 Valid Exchange

This adaptive model ensures continuity even during unexpected outages while preserving accuracy under normal conditions.

Impact on Trading and Risk Management

Changes in index composition may cause temporary fluctuations in the reference price. Since these indices influence:

Frequently Asked Questions

Why was Coinbase replaced with Kraken in the STX index?

Kraken demonstrated stronger and more consistent liquidity for STX pairs during evaluation periods. Its inclusion improves price accuracy and reduces reliance on less active markets.

Does changing one component significantly affect the index price?

Typically, no—due to diversification across five exchanges. However, short-term discrepancies may occur if Kraken’s pricing differs notably from others during volatile moments.

How often are index components reviewed?

OKX conducts regular reviews based on liquidity, trading volume, data reliability, and market depth. Adjustments are made only when necessary to maintain index integrity.

What happens if multiple exchanges go offline?

The adaptive calculation model switches to fewer valid sources. As long as at least one exchange reports valid data, the index continues running—though with reduced resilience.

Can I track which exchanges contribute to an index in real time?

Yes. OKX provides transparent access to index composition and real-time data sources through its public API and trading interface.

Do these changes affect spot trading?

No. These adjustments apply only to index values used in derivatives pricing and do not impact spot market mechanics or trading pairs.

By maintaining a transparent, rules-based approach to index management, OKX reinforces its commitment to fair and resilient markets. Traders benefit from enhanced data quality, reduced manipulation risk, and clearer risk parameters—essential elements in today’s fast-moving digital asset landscape.
