Description

Expected Behavior

Custom data types should be able to update security OHLC properties if they contain user defined OHLC fields that follow a name convention (e.g: "Open", "High", etc.)

Actual Behavior

Custom data types update all OHLC security properties with a single fixed value from their Value attribute

  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

The issue names no files, tests, or entry points. Start by locating the custom data handling and the code that updates security OHLC properties, then identify the existing tests for custom data or OHLC values. Done means user-defined Open, High, Low, and Close fields update their corresponding security properties instead of applying the single Value to all of them.
