In depth
A modern exchange is a computer that matches orders by price and then time, not a floor of shouting traders — the NSE and BSE have been fully electronic for decades. Its two products are matching and price discovery: it does not buy or sell on its own account, and it does not guarantee that any price is fair. Settlement and counterparty guarantee are handled by an associated clearing corporation, which is why a defaulting counterparty does not become your problem. Exchanges also set listing conditions, trading hours, circuit limits and surveillance measures, and can suspend a security from trading.
Worked example
You place a limit order to buy at ₹300 while another investor places a limit order to sell at ₹300. The exchange matches them by price and time priority, the trade prints at ₹300, and the clearing corporation steps in between the two so that neither depends on the other's solvency.
Illustrative figures, chosen so the arithmetic is easy to follow. Not a live price and not a valuation of any company.
