SEBI's Algorithmic Trading

SEBI's Algorithmic Trading Framework: Regulating India's Fastest Markets

Algorithmic trading — using computer programs to execute trades at high speed based on predefined rules — accounts for over 50% of trading volume on Indian exchanges. SEBI has progressively built a regulatory framework to ensure that algo trading does not compromise market integrity, create systemic risk, or disadvantage retail investors.

Key SEBI Regulations on Algo Trading

SEBI Circular 2012: Required all algo orders to be tagged with a unique identifier, mandating stock exchanges to set limits on order-to-trade ratios (OTR). Exchanges penalise members with excessive OTRs. Co-location Policy (2015–16): SEBI mandated that co-location facilities (placing servers physically close to exchange servers for ultra-low latency) must be made available on equal terms to all eligible members, preventing unfair advantages. Risk Controls (2012 onwards): Mandatory maximum order value checks, price bands, quantity limits, credit checks, and automatic shutoff mechanisms for all algo systems.

SEBI's 2021–22 Algo Framework for Retail

SEBI proposed a framework for retail algo trading in 2021, which would require all retail algo products offered by brokers to be approved by stock exchanges. The framework mandates that: (1) Each algo strategy must be uniquely tagged. (2) Brokers remain accountable for client algos. (3) No third-party API providers can offer unregistered algo services. This proposal, still evolving, aims to protect retail investors from unregulated automated tip services.

Compliance Requirements for Algo Traders

If you are a SEBI-registered entity operating an algo system: (1) Get the algo approved by the stock exchange before deployment. (2) Maintain detailed audit trails for 5 years. (3) Implement automatic kill switches. (4) Conduct half-yearly system audits. (5) Report any algo malfunctions to the exchange within 24 hours.
