Sebi Eases Algo Trading Rules for Liquidity
Overview

The Securities and Exchange Board of India (Sebi) has significantly adjusted its order-to-trade ratio (OTR) framework for algorithmic trading. Effective April 6, 2026, the regulator is expanding exemptions for equity options contracts and excluding market-making activities from penalty calculations. This recalibration aims to bolster market liquidity and efficiency by reducing regulatory friction for key trading functions, while maintaining deterrents against disruptive behavior.

1. THE SEAMLESS LINK (Flow Rule):

The recent recalibration of India's order-to-trade ratio (OTR) framework for algorithmic trading marks a strategic pivot by the Securities and Exchange Board of India (Sebi). This adjustment prioritizes fostering enhanced market liquidity and operational efficiency, particularly within the derivatives segment. By strategically widening exemption thresholds for equity options and explicitly excluding designated market-making activities from penalty computations, Sebi intends to cultivate deeper, more resilient trading ecosystems. This move signals a regulatory approach that is evolving beyond mere punitive measures to one that actively supports essential market functions.

2. THE STRUCTURE (The 'Smart Investor' Analysis):

Calibrating OTR for Options and Market Makers

Sebi's revised norms introduce a broader exemption band for algorithmic orders in equity options, now covering trades within ±40 per cent of the last traded price (LTP) premium or ₹20, whichever is greater. This contrasts sharply with previous, more restrictive thresholds that frequently led to penalties and market participant consternation, especially in the volatile options segment. Furthermore, the exclusion of algorithmic orders placed by designated market makers for liquidity provision activities from OTR penalty calculations is a critical development. This is designed to encourage greater participation from entities vital for price discovery and bid-ask spread compression, recognizing their role in market depth. The framework's application now explicitly exempts these market-making orders from penalties associated with high cancellation rates, a move intended to support liquidity provision without compromising the core intent of deterring non-economic order placements.

Historical Context and Regulatory Intent

The OTR framework, introduced to curb manipulative and excessive order placements, has seen previous adjustments in response to market feedback. Earlier iterations often faced criticism for being overly stringent, potentially stifling legitimate high-frequency trading strategies and reducing overall market dynamism. This latest revision, influenced by consultations with stock exchanges and Sebi's Secondary Market Advisory Committee, reflects a more nuanced understanding of algorithmic trading's role. The intention is to strike a delicate balance: promoting market efficiency and liquidity, essential for investor participation and price discovery, while continuing to deter disruptive trading behaviors that could undermine market integrity. The previous master circular for stock exchanges and clearing corporations, issued in December 2024, has been modified to incorporate these changes.

Supporting Market Efficiency and Future Impact

Effective from April 6, 2026, the revised framework mandates that stock exchanges update their bye-laws and disseminate these changes. Market participants anticipate that the increased flexibility in options trading and the supportive stance towards market makers will lead to tighter spreads and potentially increased trading volumes in derivatives. Globally, regulators are increasingly focusing on the interplay between algorithmic trading, liquidity provision, and market stability, with many jurisdictions offering specific frameworks or carve-outs for market-making activities to ensure robust price formation. Sebi's action aligns with this trend, signaling a commitment to modernizing India's trading infrastructure to meet evolving market demands and technological advancements.
