Dear HTX Users,

To provide more transparent market data services, HTX will introduce a new Index Price Components and Weights query feature on the Futures Market Data page, effective February 13, 2026, at 02:00 (UTC). Additionally, to ensure consistent naming conventions, we will optimize and standardize the displayed names of source exchanges within the relevant API interfaces. Please see the details below:

I. New Feature: Index Price Components & Weights Query

Once the feature is live, you can view the component exchanges and their respective weights for specific trading pairs using the following paths:

• Web: Top Navigation Menu → Futures → Futures Information → Index → Select Futures Symbol → View Components & Weights.
• App: Futures Trading Page → Top-right "..." → Data → Market Date → Index → Select Futures Symbol → View Components & Weights.

II. Normalization of Source Exchange Naming

To ensure the accuracy and readability of data source identifiers, we have standardized the names of source exchanges across our API interfaces. This adjustment only affects the display names (strings) and does not impact the underlying data or API integration methods.

• API Endpoint: /linear-swap-api/market/swap_contract_constituents ([General] Get index components )
• Relevant Field: exchange (Source Exchange)
• API Documentation: Click here to view documentation

The comparison of exchange names before and after the adjustment is outlined below:
