Stock Exchange

What is the role of a Stock Exchange in buying and selling
shares?
The stock exchanges in India, under the overall supervision of the regulatory
authority, the Securities and Exchange Board of India (SEBI), provide a
trading platform, where buyers and sellers can meet to transact in
securities. The trading platform provided by NSE is an electronic one and
there is no need for buyers and sellers to meet at a physical location to
trade. They can trade through the computerized trading screens available
with the NSE trading members or the internet based trading facility provided
by the trading members of NSE.
