User ID

The trading system of the Exchange is accessed by the trading member through various modes of connectivity with a unique identification number called User ID. The User ID is a system generated number which is allotted to an individual who is recognised as “Approved User” of the Trading Member.

User ID - Types and Certification requirement:

NEAT ID: Neat IDs are issued to trading members to access the trading platform of the Exchange. Each NEAT user is assigned a status as Corporate Manager / Branch Manager / Dealer. These IDs are issued to Approved user depending on fulfilment of the certification requirement as may be specified by SEBI/Exchange, from time to time.

Members have an option to convert their NEAT IDs to Non-Neat Front end (NNF)/CTCL and/or enable them for CTCL/STWT/DMA/IBT and shall report the details of 12 digit CTCL/IBT/DMA/STWT terminals to the Exchange before routing any order through such terminals.

Details of all CTCL/IBT/DMA/STWT terminals (activations as well as deactivations) irrespective of purpose (Trading / Testing / View / Admin) shall be reported to the Exchange in advance. The facility to report the CTCL/IBT/DMA/STWT terminal data can be accessed through the electronic interface provided by the Exchange (ENIT) through the following path (ENIT Login > Trading > Member Reporting Pre-Trade > CTCL ID Activation).

Further, trading members can carry out their order activity on the same day subsequent to their upload of their CTCL /IBT/DMA/STWT terminals through ENIT. The 12 Digit Terminal ID will be activated from the date mentioned in CTCL Activation request.

Failure to upload the details, by a member, if observed shall render such terminals unauthorized and shall consequently attract disciplinary action as prescribed by the Exchange from time to time.

The approved persons reported by the member should have valid certification, as may be applicable from time to time.

Trading member desirous of obtaining user IDs are required to meet certification requirement as specified by SEBI /Exchange from time to time. Applicable requirement are as follows: Segment Applicable norms

Non-NEAT ID: Exchange has provided a separate category of Non-Neat user without NEAT login facility along with the current categories of users. Members are requested to note that such category of user shall not be allowed to login/ trade through NEAT/NEAT Plus. Members will be required to build additional back up facilities for exigency. This category of user will not be required to provide any certification as the user does not have trading eligibility by itself.
