information, communication and network technologies have created paradigm shifts
in the securities market operations. Technology has enabled organisations to
build new sources of competitive advantage, bring about innovations in products
and services, and to provide for new business opportunities. Stock exchanges all
over the world have realised the potential of IT and have moved over to
electronic trading systems, which are cheaper, have wider reach and provide a
better mechanism for trade and post trade execution.

the organisation to retain its competitive edge and ensure timeliness and
satisfaction in customer service. In recognition of the fact that technology
will continue to redefine the shape of the securities industry, NSE stresses on
innovation and sustained investment in technology to remain ahead of
