SEBI Algo Trading Norms Come into Effect: Two-Factor Authentication, Audit Trails Mandated for Brokers
SEBI's New Rules on Algorithmic Trading for Retail Investors Come into Effect Today
The Securities and Exchange Board of India's (SEBI) new rules on algorithmic (algo) trading for retail investors come into effect today, 1 April 2026, marking a significant shift in how automated trading strategies can be accessed and regulated in the country. In a circular issued in February last year, the capital markets regulator announced a framework to facilitate safer participation of retail investors in algo trading, with stock brokers and exchanges playing the required roles in risk management, ensuring proper checks and balances, safeguarding investor interest as well as integrity of the market.
SEBI outlined a series of measures to strengthen oversight, enhance accountability, and mitigate risks associated with the growing adoption of algo trading among individual investors. The new rules aim to create a safer and more transparent environment for retail investors venturing into automated trading.

The new framework introduces several key features to regulate algo trading, including:
| Feature | Description |
|---|---|
| Structured API access | Brokers will act as principals, while third-party algo providers or fintech vendors will function as their agents. All algo orders originating through API extended by brokers to algo providers shall be tagged with a unique identifier provided by Stock Exchange. |
| Tighter controls | Brokers have been directed to discontinue open APIs and instead allow access only through secure, client-specific API keys linked to static IP addresses. Additionally, authentication must be upgraded to OAuth-based systems with mandatory two-factor authentication. |
| Record-keeping | Brokers must maintain detailed records of all algo trades, including time, price, quantity, and order IDs to ensure auditability. |
| Two-factor authentication | API access must be secured with mandatory two-factor authentication, password expiry policies, and daily auto-logout systems. |
Broker Accountability and Investor Protection
According to the SEBI circular, brokers must obtain approval from the exchange before offering any algo trading facility and are required to tag all algo orders for audit purposes. Brokers will be solely responsible for handling investor grievances related to algo trading and the monitoring of APIs for prohibited activities.

Brokers can only partner with empanelled algo providers, and must conduct due diligence before onboarding them. Any revenue-sharing arrangements between brokers and algo providers must be transparently disclosed to clients, with safeguards in place to prevent conflicts of interest.
Enhanced Role of Exchanges and Risk Controls
Stock exchanges are required to establish standard operating procedures (SOPs) for algo testing, conduct continuous surveillance, and retain the ability to deploy “kill switches” to halt malfunctioning algorithms. Exchanges will also define turnaround times for algo approvals, with provisions for faster clearance of simpler execution algos.
By clearly defining the roles of brokers, exchanges, and algo providers, SEBI aims to create a safer and more transparent environment for retail investors venturing into automated trading. The new rules are seen as a significant step toward democratizing algo trading, while ensuring that adequate checks and balances are in place.
Investor Takeaway
Investors should be aware of the new rules on algorithmic trading and its potential impact on their trading strategies.
