There are 23 stock trading systems in India, the most important of which are Mumbai Stock Exchange (BSE) and National Stock Exchange (NSE). In 2005, the trading volume of national stock exchanges was second only to new york Stock Exchange and Nasdaq Stock Exchange. As the second largest market in India, Mumbai Stock Exchange ranked fifth in the world in terms of trading volume in 2005. However, all along, the "Indian stock market" mentioned by various media actually refers to the Mumbai Stock Exchange, and its SENSEX-30 index has almost become synonymous with the Indian stock market.

1995, the Mumbai Stock Exchange has realized online trading and computer operation of all stocks. At present, more than 6,000 companies are listed on the Bombay Stock Exchange, with 2,500 active companies, which makes the Bombay Stock Exchange the gateway to the Indian capital market.
