Maximise your compliance, performance, and reach under India’s new retail algo framework—effective 1 October 2025.

🌎 Introduction

In a historic step to democratise and secure algorithmic trading, the National Stock Exchange (NSE) has formalised its retail algo-trading guidelines based on SEBI Circular No. SEBI/HO/MIRSD/MIRSD-PoD/P/CIR/2025/0000013. Effective 1 October 2025, these norms ensure every automated order is transparent, traceable, and SEBI-compliant.

Whether you’re a retail trader, fintech innovator, or broker, here’s everything you need to thrive under the new regime.

🔍 Key Highlights of the NSE Circular

1. Every Automated Instruction Is an “Algo Order”

All trades executed via software logic—including Client Direct API—must be tagged and controlled as “Algo Orders” under NSE’s new standards.

2. White-Box vs. Black-Box Classification

TypeLogic DisclosureRegistration ProcessTimeline
White-BoxFully disclosed (e.g., TWAP/VWAP)Fast-track with basic docs7 working days
Black-BoxProprietary, hidden (e.g., HFT, arbitrage)SEBI Research Analyst registration + strategy dossier30 working days

Firefly by Fintrens is classified as Black-Box yet operates fully within these limits.

3. OPS Threshold: 10 Orders/Second

  • ≤ 10 OPS: No formal exchange registration
  • > 10 OPS: Broker-facilitated NSE Algo ID registration required
  • 🔐 All algo orders must still use static IPs, OAuth 2FA, and carry audit tags

4. Mandatory Static IP & Two-Factor Authentication

  • Map each API key to a dedicated static IP (updatable once/week)
  • Enforce OAuth-based 2FA on every session
  • Require daily logout for all API connections

5. Comprehensive Audit Trails & Kill Switches

  • Tag every algo order (NNF 13th digit = 0)
  • Brokers must store 5-year, end-to-end logs
  • NSE can deploy “kill switches” on erratic or non-compliant strategies
