Description

NSE issues consolidated circular on trading connectivity options including Connect2NSE platform access via existing leased lines and new IP connectivity scenarios for trading members.

Summary

NSE has issued a consolidated circular on trading connectivity for trading members. The circular provides application forms and procedural details for two connectivity scenarios: accessing the Connect2NSE platform through existing leased line trading connectivity, and applying for new IP connectivity (Scenario-based leased line setups). The circular outlines available categories, service modes, segment options, and the application process for activating connectivity scenarios.

Key Points

  • Trading members can access the Connect2NSE platform using their existing commissioned leased line connectivity by submitting Annexure 6.
  • New IP connectivity applications (Form IP-1) allow members to apply for activation of specific scenarios at Main, Branch, Registered, Corporate, Authorized Person offices, or Third Party Data Centers.
  • Ten categories (A through H, O, S) are available, ranging from 40 to 10,000 interactive messages with varying market data broadcast options.
  • Two service modes available: Managed Service Mode (MS) and Self Service Mode (SS).
  • Supported trading segments: Capital Market (CM), Futures & Options (F&O), Currency Derivatives (CD), and Commodity (CO) — CO segment capped at 120 messages per second per IP.
  • Scenarios range from single leased line (e.g., A2, B1, C1) to dual leased line (e.g., A4, B2, C2) configurations.
  • Subnet IP activation must be applied through ENIT > Membership > TCP IP Activation > Child IP.

Regulatory Changes

This is a consolidated circular consolidating existing NSE connectivity guidelines and application procedures. No new regulatory mandates are introduced; the circular formalises and standardises the process for trading connectivity access and scenario activation.

Compliance Requirements

  • Trading members wishing to access Connect2NSE via existing leased lines must submit a written application (Annexure 6) on company letterhead to NSE’s Member Service Department, citing the NI Reference ID and commissioned IP details.
  • Members applying for new connectivity must complete Form IP-1 (Annexure 7) specifying member name, code, desired category, service mode, number of routers (for MS mode), message segmentation preference, and the applicable scenario.
  • Applications must be submitted to: Member Service Department, National Stock Exchange of India Limited, Exchange Plaza, Bandra-Kurla Complex, Bandra (East), Mumbai – 400051.
  • At time of enablement, message allocation will follow the opted segmentation; NSE may rebifurcate messages if enabled segments differ from opted segments.

Important Dates

  • No specific effective date or deadline is mentioned in the circular content. Members should refer to the full circular on the NSE website (www.nseindia.com) for any applicable dates.
