Is Algorithmic Trading Legal and Profitable in India?

In the financial market there are various terminologies but you might have also come to words like algorithmic trading, or algo trading. Here the basic thing is trading is done by using computer programs to automatically buy and sell stocks in the share market. Instead of you clicking the buttons, a pre-written code does it for you based on a set of rules.

With the advancement in technology algorithmic trading is very popular in India, but it raises some big questions. Is it a reliable way to make money? Is it even legal for a regular person to use? Many people are asking, is algo trading profitable? They want to know if algo trading is legal in india and if algo trading is profitable in india. These are important questions, especially when considering if trading is profitable in India overall.

In this blog we will understand how algo trading works and its features and its legality in the financial trading world. 

What is Algorithmic Trading?

In Algo trading the trading is done using a computer program to place buy and sell orders in the stock market. This program follows a pre-defined set of instructions, or an algorithm, that you create. The users or investors need to set the Price of the stock and Buy a stock if its price crosses its 50-day average and Sell a stock at 3:15 PM every day. And investors need to buy a stock if its trading volume doubles in an hour.

Here you need to create the strategy and on the users behalf the computer just does the work.

The investors need to be clear about the stocks they want to invest in and provide step by step instructions, the rules for buying and selling. The algorithm is like an automated robot where you can instruct and see the magic happening on its own.

First you need to watch a stock of the selected company, if there is rise of 1% or 2% in price then as per instructions you can buy and if it starts to fall then you sell it also if you start to face the losses on the assets you have bought then you can sell to limit down your losses. The computer monitors the market every second and executes these orders instantly when these conditions are met.

Manual Trading vs. Algo Trading

The difference between trading yourself and using an algorithm is vast:

• Manual Trading: In this type of trading you monitor the screen, do the research, take your decisions and make your own decisions, here decisions can sometimes be emotional or outdated. 
• Algo Trading: In this type of trading computer program executes the trade and the decisions are based on pre-set rules and analysed available data. Here, possibility of human error and emotions can be wiped out and you can have well informed decisions for your future trades. 

Is Algorithmic Trading Legal in India?

Here comes the most critical question if algorithmic trading is legal or not and the answer is yes, algorithmic trading is completely legal for retail investors in India. However, it’s not a free-for-all. SEBI being the market regulator has a strong framework to protect the interest of investors and make the market a stable and fair place for everyone.   

SEBI’s main job is to make the financial market a safe place for the investors and with algo trading the risks are higher due to the speed and automation of the process. A fault in the algorithm can sometimes place a wrong order in a fraction of seconds that can even lead to heavy losses. The rules are designed to present this and protect the traders from fraud and manipulation.   

SEBI’s New Rules (Effective August 2025)

SEBI has introduced a new set of rules to make algo trading safer for retail investors. You need to look upon the following points:   

• Inter-connected Platforms: You cannot connect your trading software directly to the stock exchange (like NSE or BSE). Every single order from your algorithm must pass through your stockbroker’s systems. The broker acts as a checkpoint, ensuring every order is legitimate before it hits the market.   
• Mandatory Approvals: The strategies used shall always be approved by the stock exchange, this is done to make sure the strategy does not manipulate the financial market.   
• Unique Algo ID: Unique IDs are provided to all the algo traders which helps SEBI track all automated orders and investigate if something goes wrong.   
• “White Box” vs. “Black Box”: SEBI has classified algos into two types, first is the White Box where trading is done in a simple and transparent way and second is the Black Box where the trading logic is secret or very complex. Anyone selling a “black box” strategy must be registered with SEBI as a Research Analyst, which adds a layer of accountability.   
• No More Open APIs: To enhance security, SEBI has banned open APIs. You will need to use a secure connection with measures like a static IP address, which your broker will help you set up.   

Is Algorithm Trading Profitable? 

• Simple Strategy: Don’t overcomplicate things as many beginners believe a strategy with a dozen indicators is smarter but in algo trading the opposite is often true. Simple, clear rules are easier to test and tend to work better when the market changes unexpectedly. A complex strategy might just be good at explaining the past, not predicting the future.
• Test Realistically: Looking at how your strategy performed on past data (backtesting) is a must. Your backtest might show a profit, but once you add brokerage, taxes, and slippage (the small price difference when you actually buy or sell), that profit can shrink or even disappear. These costs can cut your returns significantly, so always include them in your tests.
• Don’t Over-Optimize: It’s easy to keep changing your strategy’s rules until it looks like a perfect money-making machine on past data. This is a huge trap called “over-optimization”. You tend to look at market views, expert guidelines and various podcasts but the live market is always different, and such a strategy will likely fail. A good strategy should work reasonably well on different sets of past data, not just one perfect scenario.
• Manage Your Risk Strictly: Your first job isn’t to make profits; it’s to avoid big losses. This means using stop-losses to cut a losing trade short and deciding beforehand how much money you’ll risk on each trade. One bad trade should never be able to blow up your account. Poor risk management is the fastest way to lose money.
• Count All the Costs: A strategy might seem profitable on paper, but costs are real. You have to subtract brokerage, taxes (like STT and GST), platform fees, and API charges. For strategies that trade many times a day, these small costs can add up and turn a winning strategy into a losing one.
• Always Keep an Eye on It: Algo trading is not a “set it and forget it” system. The market changes, what works in a rising market might get crushed in a flat one. You need to watch how your algorithm is performing and be ready to step in or turn it off, especially when the market goes crazy or if there’s a technical problem.

Understanding the Costs

• API and Platform Fees: Some brokers offer free APIs to its users while some charge monthly fees and some no-code platforms have different subscription plans.   
• Infrastructure Costs: Advanced traders use Virtual Private Server (VPS) to run their algorithms 24/7. This is a small monthly cost but ensures your system is always online.
• Transaction Costs: Traders are bound to pay the basic trading charges like brokerage, Securities Transaction Tax (STT), exchange charges, etc. For frequent traders these costs can add up and consume your profits significantly.   

The Advantages of Algorithmic Trading

• Lightning Speed: By using algo trading traders can execute trades within milliseconds and can even capture even the small price movements that can be tough for humans to react instantly.
• Flawless Accuracy: Algo trading can reduce human errors making trading experience more accurate and error free. 
• Rigorous Backtesting: Algo trading can help you with multiple years of data and its quick analysis for your next trading move.
• Emotion-Free Discipline: This is one of the biggest advantages of Algo trading, as per SEBI over 90% of the retail traders make losses in their trades due to improper study and emotional decisions. Algorithms derive the decisions from data and its in depth analysis.  

The Disadvantages of Algorithmic Trading

• Added up Costs: Users have to pay multiple fees like API fees, platform subscriptions and basic transaction charges as adding all this up can directly hit your profits. 
• Technological Faults: There can be an internet issue or what if there is a bug in your code or the broker’s API has an outage during the crucial market hours, these types of technical failures can be risky.   
• Dependency: A smart trader uses a mix of both, their skill set and a good strategy but totally relying on the technology without a certain skill set can turn out to be negative for your financial future. 
• Over-Optimization: This is one of the mistakes that traders make as optimization uses data that is based on past data which can give you a result that can perform negatively in the live markets.
