National Stock Exchange (NSE) on 5 May 2025, announced the standards for algo trading to align with the new norms SEBI framed for ensuring the safety of retail traders in this segment. These standards will be implemented from 1 August 2025. In February 2025, SEBI made this mandatory that institutions offering algorithmic trading need to register with the stock exchanges. This is when SEBI framed the norms for using the algo trading APIs (application programming interfaces). The notion behind these norms is investors’ protection and safety.
What is Algo Trading?
Before looking at the standardization norms mandated by the NSE and SEBI, let’s understand what algo trading is all about. So, algo trading is an abbreviation for algorithmic trading, and as the name suggests, different algorithms are used to develop programs for the execution of trading orders. As humans can’t place multiple trades within seconds, algo trading comes in to boost the speed and frequency of trading. There are different algorithms with defined sets of timing, quantity, pricing information, and any other numerical values that are used for stock trading.
In simple terms, algo trading incorporates financial markets data and computer programming (algorithms) to place and execute trade orders within the blink of an eye.
Key Compliance Norms
As NSE has come up with the compliance norms, as directed by SEBI, here are the main changes that one can observe in the algo trading platforms.
- There is a concept of Threshold per second (TOPS). Now, the algos that exceed this TOPS must get registered. Currently, as per the NSE circular, the TOPS has been decided to be 10 orders per second. So, if any algo can generate more than 10 orders per second, then that needs to be registered.
- If the orders are brought by APIs, then those also need to be tagged as algos for risk management.
- If any unregistered algo crosses the TOPS, it will be slashed out of the trading system. It is the broker who needs to reject such an order when orders cross TOPS from unregistered algos and shouldn’t process the same. Brokers offering API connectivity to the traders must also have the system or facility to monitor as well as control the threshold limit for unregistered algos.
- While brokers can create and share different algos with the clients, those need to be registered in the first place. If they want to provide the algos independently, then they need to be on the exchange’s panel, and then the exchange can assign an ID to each algo. Registered algos can be used across brokers.
- Algo providers can separately join hands with the brokers by entering into agreements against particular fees or charges.
- Retail traders can also develop their algos and get those registered with the exchanges. This can help the retail traders who are interested in algo trading, but due to safety issues, haven’t gotten the confidence yet.
- For registering algos, retail traders can develop the algo themselves or with the help of tech vendors. Then he or she must provide the details to the brokerage house he or she is associated with. Then the broker will take the thing forward to the exchange and get the algo registered. Once the algo is registered, the broker will share the algo ID with the client.
· In the same manner, the retail trader can modify the algo as well.
- All the algo orders will be tracked, and the details will be kept for five years. This is again for safety and audit purposes, irrespective of the system from which the algo order is fired. It can be an internet-based trading system, or API of the client or the vendor, or STWT platforms.
- In case of using multiple algos, all of them need to be mapped to a primary or a secondary static IP.
- A static IP can only be shared within the family. While it can be mapped only to one client, but shared within the same family members.
- A static IP can be changed only once a calendar week if required. In case the client needs to change it more than once in a week, he or she needs to reach out to the brokerage house.
- Brokerage houses will be monitoring the algo trading compliance standards
With due diligence as per the NSE circular. It will be the duty of the brokerage house to make sure there is no misconduct or violation of the securities laws. If there is any such incident, then the broker needs to immediately report the same to the stock exchange/s. - The stock exchanges will be monitoring and have surveillance over the entire system with SOPs for testing algos, real-time simulation testing, and surveillance, and a system to halt or destroy algos that are malfunctioning.
Why is this standardization necessary?
Earlier, it was only the institutional investors who were using Algo trading platforms. However, with the growth in retail participation in the markets, across segments, algo trading has been gaining immense importance. While this form of trading can be highly beneficial for super-fast trade execution, knowledge and compliance are necessary.
This is why SEBI asked the stock exchanges to frame the standards for algo trading and made registration of algos mandatory if the algos exceed the threshold. This will ensure that retail traders do not get exposed to unnecessarily high risks that are associated with automated trading platforms.
Wrapping up
While this has been long overdue and SEBI and the stock exchanges have been working on it for a long time, finally, the standards are here. It is about time as these will be implemented. It has long been longed for by the retail traders as algo trading is gaining importance, but the safety has been an issue. With these SEBI operational norms, stock exchange regulations, and brokerage houses monitoring the algo providers, the retail investors can participate in algo trading without fear.
Algo Trading Compliance | FAQs
This is the maximum number of orders that an algo can fire within a second. Currently, it has been decided as 10 orders per second.
Here, SOPs refer to Standard Operating Procedures, which will be put to use for testing the algorithms.
STWT refers to Security Trading Through Wireless Technology Platforms.
This is a fixed IP address assigned to a device, and it won’t change under any circumstances.
On 1 August 2025, all these standardizations will come into effect.
