Haircut Change Log

Query the change history of product Haircut (collateral discount rate) configuration, used by risk control to audit every Haircut adjustment.

Request parameters

Combine business filters through filters (optional fields are listed in the filters field notes below), and use page, page_size, and orderBy for pagination and sorting.

Business notes

The data comes from the Haircut configuration change log; each record represents one Haircut change for one product (counter_id).
Each record carries the product identifier and name, old_haircut (before), new_haircut (after), op (operation type), source (origin of the change, such as a manual edit or a change triggered by an index rule), update_user, and the created and updated timestamps.
It supports tracing how collateral discount rates changed over time for risk and compliance audit.

Returns

On success, returns the matching record list with pagination. See the response definition for column meanings.
