Co-location is the practice by institutional investors to locate their servers on the site of the stock exchange, in exchange for a fee, to cut down on latency and trade that much faster.

This was launched by the NSE in 2010. Co-location accounted for 8 per cent of the derivatives trading at the NSE in FY11, which jumped to over 17 per cent in FY12.
