Trading Mechanism in National Stock Exchange
1.1 Meaning of Trading Mechanism
The trading mechanism in the stock exchange is based on a transaction between a buyer, seller, and a trading specialist who actually executes transactions in a stock exchange. In general, the trading mechanism is similar to a simple auction, with investors biddng on a particular stock or security. If the bid is accepted by the owner of the security, the trading specialist executes the sale. Most major stock exchanges trade a collection of stocks, bonds, and other domestic and foreign investments.
The trading mechanism exists because of the constant need to channel money from investors into business entities. Investors range from wealthy individuals and investment funds to small-scale investors saving for retirement. Entities that raise money in the stock market include corporations, governments, and government agencies. The combination of investors and borrowers creates the market for securities. The trading mechanism refines the market by matching buyers and sellers with the prices they are willing to pay or take.
2. Trading Mechanism at National Stock Exchange
The trading on stock exchanges in India used to take place through open outcry without use of information technology for immediate matching or recording of trades. This was time consuming and inefficient. This imposed limits on trading volumes and efficiency. In order to provide efficiency, liquidity and transparency, NSE introduced a nation-wide on-line fully automated screen based trading system (SBTS) where a member can punch into the computer quantities of securities and the prices at which he likes to transact and the transaction is executed as soon as it finds a matching sale or buy order from a counter party. The screen based trading system offers various advantages such as: • Removes time, cost and risk of error and thereby improves operational efficiency • Faster incorporation of price sensitive information
• Improves the depth and liquidity of the market
• Provides full anonymity by accepting orders, big or small, from members without revealing their identity • Offers perfect audit trail which helps to resolve disputes by logging in the trade execution process in entirety •
Later, NSE carried the trading platform further to the PCs at the residence of investors through the Internet and to handheld devices through Wireless Application Protocol (WAP) for convenience of mobile investors.
