Algo trading for retail investors is software that places options trades automatically for an ordinary investor, by following a strategy that is set in advance. Algo is short for algorithm, a fixed set of rules that a computer follows. Retail investors are individuals who trade their own money, as opposed to funds or firms.
An option is a contract that gives its buyer the right, but not the duty, to buy or sell something at a fixed price by a certain date. In India, options on the Nifty 50 index are the most traded contracts of all. Options and futures are explained in futures and options (F&O).
A strategy is a written rule. Here is a typical case: "Every Thursday at 9:20 a.m., sell one call option and one put option on the Nifty. Close both if the loss reaches ₹3,000, or if the profit reaches ₹2,000." A person following this rule by hand must watch the screen all day. The software watches the price for the investor instead. It places the orders through the investor's stock trading app at the right moment. It closes them as soon as the loss limit or the profit target is reached.
The regulator worries about this product more than about any other retail product. Options can lose money very fast. SEBI's studies showed that most individuals who trade F&O lose money. Automation lets a person place more trades, more quickly, than they could by hand. Some sellers also promised steady returns from their strategies. So in 2025, SEBI set rules for retail algo trading. Each algorithm that a broker or an algo provider offers must now run through a registered broker and be approved by the exchange. An investor's own algorithm needs this approval only if it places more than 10 orders a second. Each automated order carries an identifier, so that it can be traced back to its algorithm. Anyone who sells strategies to the public must also follow the rules in investment advice regulation.
Retail algo trading is a small cousin of the algorithmic trading that funds use, but the two do different jobs. A fund's algorithm splits one large order that the fund has already decided on, to reduce its cost. A retail algorithm decides when to enter a bet and when to leave it. New users often test a strategy first in paper trading, with pretend money.
