- Allegations of algorithmic manipulation using high-frequency trading (HFT).
- Specific trades flagged by NSE in January 2025 involved rapid buy-sell reversals at extreme prices, possibly impacting price discovery.
- The probe is part of SEBI’s larger effort to protect retail investors, who have suffered heavy losses in F&O markets.
What is Algorithmic Manipulation?
Algorithmic Manipulation refers to the intentional use of algorithmic trading systems—such as automated, high-frequency, or black-box algorithms. This includes generating false or misleading signals about supply, demand, or price of securities, often to mislead other market participants for unfair gain.

Key Elements:
- Intentional misuse of automated trading logic.
- Distortion of market prices, order book dynamics, or trading volumes.
- Can involve spoofing, layering, quote stuffing, or momentum ignition.
- Violates principles of market integrity and transparency.
India’s Current Legal Framework:
- SEBI (Prohibition of Insider Trading) Regulations, 2015:
- Focuses on preventing misuse of Unpublished Price Sensitive Information (UPSI).
- Enacted for traditional manual trading; lacks specificity for algorithmic contexts.
- Insufficient to track automated insider trading without AI-enabled enforcement tools.
- Key Gaps Identified:
- Absence of mandatory algorithm disclosure and audit norms.
- No clear definition or legal interpretation of “algorithmic intent”.
- Limited tech-based surveillance and reliance on post-facto compliance reviews.
