NSE Retail Algo Trading Rules
Now that you know the key circulars that define the rules linked to algo trading, it’s time to find the common rules that you must know. So, in addition to the algo trading strategies, these are the rules that you need to know:
Rule | Details |
Definition of Algo Orders | Any order placed through APIs or automated execution logic is treated as an algorithmic order, whether developed by the client, broker, or third party. |
Broker Responsibility | Brokers are fully responsible for orders placed via their APIs. It is their duty to check the eligibility and supervise the client's usage as well. This is important to apply risk management checks. |
Unique Algo ID | This is applicable to every strategy. You must register the strategy if there are any changes in the logic or design. |
Order Per Second Threshold | If an algo generates more than 10 orders per second, it must be registered. This should be done with the exchange and subject to stricter compliance. |
Static IP Whitelisting | Static IPs must be used. This is for all the retails clients who are using APIs. These must be whitelisted by the broker for secure access. |
Two-Factor Authentication | For security, two-factor authentication is crucial. All APIs need this for an added level of safety. |
Session Expiry | There is a chance that APIs will expire on their own after some sessions. You will need a fresh login for the next trading day. |
Family Sharing of IPs | Static IPs can be shared among family accounts, provided they meet SEBI’s definition of family and proper documentation is provided. |
Audit and Reporting | All algo trades must be logged with complete audit trails. Exchanges and SEBI can call for audits whenever required. |
Exchange Authority | Any algo that is not working right or is misbehaving will be terminated or disabled immediately. This will be done by the exchange to disrupt market functioning. |
Future of Algo Trading in India
Algo trading in India is still in the very starter stages. The wider adoption calls for stricter rules and strategies that can help with better trades. Here is what the future of algo trading looks like:
Rise of broker-led algos:
The number of brokers supporting plug-and-play strategies will rise. This will help the retail clients who are not well-versed in codes.
Possible revision of OPS limits:
The current 10 orders per second cap may be relaxed. This will help in strengthening the infrastructure.
Greater use of AI-driven models:
Predictive and adaptive algorithms that use AI will be common. This will be quite helpful in the retail trading space.
Tighter cybersecurity rules:
Static IPs, two-factor authentication, and secure hosting will be common. This will not be just mandatory but also will help in future expansion.
Better monitoring systems:
For better trading and transparency, there will be a need for stricter monitoring guidelines. Algos not in use would need to be disabled quickly.
Mainstream adoption:
A proper framework will make algo trading even more common. This is applicable to retail investors in India.
