Our Technology

Across the globe, developments in 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.

NSE believes that technology will continue to provide the necessary impetus for 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 competition.
