What is the Role of a Stock Exchange?

A stock exchange is more than just a place where stocks are bought and sold—it’s the heartbeat of a nation’s financial system. Think of it as a giant, highly organized marketplace where investors trade shares, bonds, and other financial instruments like Exchange-Traded Funds (ETFs). Stock exchanges provide a secure, transparent, and regulated environment that protects both buyers and sellers while promoting economic growth.

In India, stock exchanges are overseen by SEBI (Securities and Exchange Board of India), which ensures fair trading practices, safeguards investors, and fosters the organized growth of capital markets.

🛠️ How Does a Stock Exchange Work?

In India, stock exchanges operate primarily on electronic trading systems. Here’s a simplified step-by-step process:

1. Place an Order: You instruct your broker to buy or sell a specific stock.
2. Order Transmission: Your broker sends the request to the stock exchange.
3. Order Matching: The exchange matches your buy order with a corresponding sell order.
4. Trade Confirmation: Once matched, the trade is executed and confirmed.

This order-driven system ensures transparency by showing real-time market prices and available orders. Investors can see the demand and supply dynamics, making the process fair and accessible.
