Accessing Historical CSI 300 Data in the New Backtest Engine

Summary

This brief platform support exchange addresses why a historical-data call for the CSI 300 index is not recognized. The response says the newer backtest engine retrieves data through SQL and suggests using the platform’s data interface to obtain index data for the current day.

The post signals that data access methods depend on the backtest engine version, which matters when adapting code between older and newer environments. However, it gives no complete query, field schema, worked example, or explanation of how to retrieve a multi-day historical series. Its practical guidance is therefore limited to the general direction of using SQL-based access in the newer engine and the platform’s data interface for daily index data.

Key ideas

  • The older history call may not work in the newer backtest engine.
  • The response points users toward SQL-based data retrieval in the newer engine.
  • The platform data interface is suggested for retrieving current-day index data.
  • The post does not provide a complete historical query or a worked example.
