The CBI has filed a supplementary chargesheet in the NSE co-location case, targeting brokers who allegedly benefited from the scam. The chargesheet details the modus operandi of broker firms, including the use of a software called Chankaya to exploit NSE's Tick-By-Tick architecture. This follows previous legal actions, including a 2022 chargesheet against Sanjay Gupta, Chitra Ramkrishna, and others. The case, initiated in 2018, involves allegations of unfair market access and raises questions about market integrity in India's financial sector.

The Central Bureau of Investigation (CBI) has intensified its probe into the National Stock Exchange (NSE) co-location case by filing a supplementary chargesheet. This latest development focuses on the brokers who allegedly benefited from the scam, shedding light on their involvement and methods of operation.

Details of the Supplementary Chargesheet

The new filing by the CBI provides a detailed account of the role played by various broker firms in the NSE co-location case. It outlines the modus operandi employed by these entities to gain unfair advantages in the stock market.

Background of the Case

The CBI's involvement in this case dates back to May 2018, when it registered a First Information Report (FIR) against stock trader Sanjay Gupta and OPG Securities. The FIR was filed under sections pertaining to:

  • Criminal conspiracy
  • Information Technology Act
  • Prevention of Corruption Act

Allegations and Modus Operandi

The core allegation in the FIR states that NSE officials facilitated OPG Securities in connecting to the exchange's backup server. This connection allegedly provided OPG Securities with improved and faster access to market feed, giving them an edge over other market participants.

The method reportedly involved exploiting NSE's Tick-By-Tick (TBT) architecture using a software called Chankaya. This setup purportedly allowed the accused to gain unfair advantages in their trading activities.

Previous Legal Actions

This is not the first chargesheet filed in the NSE co-location case. In 2022, the CBI had previously filed a chargesheet against:

  • Sanjay Gupta
  • Chitra Ramkrishna (former NSE official)
  • Four other individuals

Since then, multiple supplementary chargesheets have been filed as the investigation has progressed and new evidence has come to light.

Implications and Ongoing Investigation

The filing of this supplementary chargesheet targeting brokers marks a significant expansion of the CBI's investigation into the NSE co-location case. It suggests that the agency is casting a wider net to encompass all parties who may have benefited from or been involved in the alleged malpractices.

As the case continues to unfold, it raises important questions about market integrity and the need for robust oversight in India's financial markets. The ongoing investigation and legal proceedings will likely be closely watched by market participants, regulators, and investors alike.
