IFSCA Issues Comprehensive Guidelines for Algorithmic Trading on IFSC Stock Exchanges

The International Financial Services Centres Authority (IFSCA) has rolled out a detailed regulatory framework governing algorithmic trading across stock exchanges operating within the International Financial Services Centre (IFSC). Issued vide Circular No. IFSCA/CMD-DMIIT/ALGO/2026-27/01 dated October 16, 2026, the guidelines establish end-to-end obligations for stock exchanges, broker-dealers, and remote trading participants, covering everything from prior approvals and risk controls to system audits and surveillance mechanisms.

This regulatory initiative is grounded in Section 12 and Section 13 of the International Financial Services Centres Authority Act, 2019, read with Regulation 72 of the IFSCA (Market Infrastructure Institutions) Regulations, 2021, and Regulation 45 of the IFSCA (Capital Market Intermediaries) Regulations, 2025.

Background and Regulatory Intent

Algorithmic trading, by its very nature, introduces both efficiency and complexity into financial markets. While it enhances liquidity and price discovery, it simultaneously carries risks of systemic disruption, market manipulation, and runaway order execution. Recognising this dual character, IFSCA has chosen to build a structured oversight architecture that balances technological innovation with prudent regulatory discipline.

The circular aims to:

  • Promote sound, orderly, and transparent development of algorithmic trading within the IFSC ecosystem
  • Strengthen market integrity and safeguard against systemic and operational risks
  • Ensure fair and equitable access to market infrastructure for all participants
  • Support IFSC's ambition to be a globally competitive financial jurisdiction

Key Definitions Under the Circular

The circular provides precise definitional clarity to avoid interpretational ambiguity:

Algorithmic Trading

Trading in securities listed on a stock exchange where a computer algorithm, program, or automated system determines — with limited or no human intervention — one or more order parameters including:

  • Initiation or cancellation of the order
  • Timing of order entry
  • Price of the order
  • Quantity of the order
  • Type of the order
  • Modification of any of the above after submission

Exclusion: Systems solely used for non-discretionary mechanical functions such as order processing, order confirmation, or post-trade processing of executed transactions are explicitly excluded from this definition.

Other Key Terms

  • Algorithmic Trading Order — Any order, modification, or cancellation initiated through algorithmic trading
  • Algorithmic Trading System — The complete suite of hardware, software, procedures, and processes used in executing and managing algorithmic trading
  • Dysfunctional Trading Algorithm — Any algorithm that malfunctions, behaves abnormally, creates loops, runaway executions, repetitive order generation, or other unintended conduct that may harm market integrity
  • Market Participants — All broker-dealers registered with IFSCA, including all Remote Trading Participants (RTPs) onboarded by stock exchanges in IFSC
  • Trading Algorithm — A computer-based set of rules, instructions, or logic applied in algorithmic trading

Obligations of Stock Exchanges

Infrastructure and Technical Readiness

Stock exchanges bear primary responsibility for maintaining a robust and resilient technological environment. Key mandates include:

  1. Clock Synchronisation — Exchange system clocks must be synchronised with the atomic clock before market commencement, maintaining a precision of at least one microsecond and accuracy of at least +/- one millisecond
  2. Resilience and Scalability — Exchange systems must handle peak order volumes and high-velocity data flows without performance degradation
  3. Tick Size Adjustments — Exchanges may revise tick sizes where necessary to ensure effective operation of price-time priority order matching systems

Approval and Conformance Framework

  • No market participant may deploy, offer, or facilitate algorithmic trading without obtaining prior express approval from the stock exchange
  • Exchanges must establish standards, procedures, and formats for evaluating, approving, monitoring, suspending, or withdrawing approval of any algorithmic trading system
  • Initial conformance testing must be conducted for every algorithmic trading system before deployment, with results communicated to the participant
  • For participants already deploying algorithmic trading as on the date of the circular, conformance testing must be completed — if not already undertaken — within three months of the circular's issuance
  • Exchanges must seek re-conformance or fresh conformance testing whenever a previously approved system undergoes material changes

Simulated Market Testing

Exchanges must periodically require participants to test their trading algorithms in simulated market environments, assessing:
