Dear HTX Users,
Thank you for your continued interest in and use of HTX’s Historical Data Download Service.
The Historical Data Download Service completed a comprehensive upgrade on June 3, 2026, and the new version has been operating stably while maintaining strong data quality since launch. To further optimize our service architecture, HTX plans to officially discontinue updates for historical data in the legacy storage bucket on August 4, 2026. Please make the necessary preparations in advance.
I. Details on Update Discontinuation
Starting on August 4, 2026, historical data under the legacy S3 storage bucket path will no longer receive daily additions or updates. The affected data types include:
• Kline (candlestick) data
• Tick-by-tick trade data
• Index Kline data
• Mark Price Kline data
II. Existing Data Remains Accessible
Historical data stored under the legacy path dated August 3, 2026, and earlier will remain available for download and will not be affected by this adjustment.
III. Migration to the New Path Is Recommended
The new S3 path has been fully upgraded in terms of structural compliance, field consistency, and data type coverage. We recommend that you update your scripts or access configurations to the new path as soon as possible to continue receiving the latest historical data.

Thank you for your continued support and trust in HTX!
