[Data QC] Corrected Disclosure Data Now Available with Waiker’s Data QC System

Because disclosure data is manually entered, errors occur countless times daily. While some are corrected through revised disclosures, many remain uncorrected, making it difficult to ensure data integrity using raw parsed data alone.

To address this issue, Waiker has been providing error codes for detected disclosure errors. With this update, we now provide not only error codes but also corrected values, affected fields, and detailed error messages!

• AS-IS: Disclosure Error Detection → Provides an Error Code
• TO-BE : Disclosure Error Detection → Provides an Error Code → Provides Corrected Values

While many stock data providers display disclosure data as-is despite potential errors, Waiker goes further by offering detailed error information and corrected values, ensuring higher data reliability.
