Indian stock exchanges, primarily the Bombay Stock Exchange(BSE) and the National stock exchanges(NSE), operate as platform where securities (stocks, bonds, derivatives) are bought and sold. Here’s a simplified breakdown.
- Investor opens an account: Investors need a Demat (dematerialized) account and a trading account to start trading.
- Place orders: Investors place buy or sell orders through their brokers.
- Order matching: The exchange’s electronic trading system matches buy and sell orders based on price and time priority.
- Trade execution: Once matched, the trade is executed, and a contract note is generated.
- Clearing and settlement: Trades are cleared through a clearing corporation, ensuring the transfer of securities from the seller to the buyer and funds from the buyer to the seller. This usually takes T+1 day (trade date plus one business day). Earlier it was T+2 days.
Below flow shows how an investor’s order travels through brokers and the stock exchange for execution
- Investor -> Broker -> Stock Exchange -> Broker -> Investor
- (Buy Order) ->(Order Matching)-> (Sell Order)
Below setup ensures a secure, regulated process for trading securities.
