The Market Data Advisory Committee (MDAC) of SEBI observed that the formats of existing
standardized data files generated by all MIIs in all segments are different and there is a need for
these formats to be standardized and harmonized in conformance to the ISO standards, which
will facilitate ease of doing business in the Indian securities market.
In accordance with the above and as per recommendations of SEBI’s MDAC, the new UDiFF
(Unified Distilled File Formats) file formats for files applicable for Equity cash (CM), Equity
Derivatives (FO), Currency Derivatives (CD) and Commodity derivatives (CO) are designed and
disseminated to members in phased manner as stipulated by ICCL.
- Uniform Data Format: Establishing a standardized format for end-of-day files ensures that
all data is presented consistently across various systems and platforms.
- Data Integrity: Standardization helps maintain the integrity of end-of-day data, reducing
the risk of errors or discrepancies during the clearing process.
- Interoperability: A standardized format enables easy integration with other systems,
promoting seamless data exchange and interoperability
- Regulatory Compliance: Adhering to standard formats ensures compliance with
regulatory requirements, enhancing transparency and accountability
Members are requested to refer the below reference circular links and initiate necessary changes
in their systems.
