SEBI Algo Trading Rules for Retail Traders (2026): What Changed and What It Means
Retail traders in India can use algorithms — but only inside a framework SEBI introduced through its circular of 4 February 2025. After two extensions, the full framework applies to all stockbrokers from 1 April 2026.
This guide summarises what the rules mean for an individual trader. It is a summary, not legal advice; read the SEBI circular and your broker's API terms for the binding details.
The core idea: every algo order is traceable
Before the framework, retail traders could connect almost any software to a broker API and the exchange could not tell which orders came from which program. Now:
- Brokers are responsible for algo orders that come through their APIs.
- Algo strategies are registered with the exchange through the broker, and their orders carry an exchange-provided strategy identifier, so any order can be traced back to the strategy that generated it.
- Brokers had to register retail algo products with exchanges and take part in mock trading sessions before onboarding clients for API-based algos.
The 10 orders-per-second threshold
Exchanges set an order-rate threshold — 10 orders per second per exchange segment.
- Below the threshold, an individual trader using their own logic through a broker API is treated as a regular API user and does not need to register the strategy separately.
- Above the threshold, the strategy must be registered with the exchange through the broker, with its own identifier.
Static IP and secure access
Brokers must make API access traceable and secure. In practice this means:
- API access tied to a static IP address registered with the broker.
- OAuth-based login with two-factor authentication for API sessions.
- Sessions that log out before the next trading day's pre-open.
White-box vs black-box algos
- White-box algos have logic that is disclosed and replicable (for example, a clearly defined moving-average rule).
- Black-box algos keep their logic hidden from the user. Providers of black-box algos must be registered with SEBI as Research Analysts and meet the related disclosure obligations.
Algo providers and vendors must be empanelled with exchanges and work through brokers; they cannot offer direct market access on their own.
What this means for you
- Use only your broker's official API and its approved process for algos.
- Be wary of anyone selling "guaranteed return" algos. A provider of a black-box strategy must be SEBI-registered, and no registered entity can promise returns.
- Keep your own logic simple, logged and testable. Rules you can explain are easier to backtest, monitor and comply with.
- Have hard risk limits that stop the algo on a maximum daily loss, a connectivity problem or unexpected behaviour. See risk management for NIFTY options.
How AITOS Trade fits
AITOS Trade is built as a research and decision-support system: market research, backtesting, paper trading and shadow monitoring. Any live trading is separate from membership and remains subject to broker authorisation, risk controls and applicable regulation.
