TRADING ACTIVITIES On 30th October 1982 the first trading at PSE was conducted in which 22 listed scripts were traded. Initially the trading was allowed only in the securities which were listed on PSE. Thereafter the trading was also allowed in the securities which were listed on the other stock Exchanges, under "Permitted Securities". Due to this, the turnover was increased substantially. From October 1982 to February 1996 the trading was conducted in the traditional fashion i.e. in the trading ring by way of open cry out system.

On 15th March 1996 the trading activities were switched over to the most advanced computerised system to fall in the line with the system prevalent in USA & Europe. PSE was the first regional stock Exchange to implement the online trading system. The project was undertaken by CMC Ltd., a Govt. Enterprise and the same was completed successfully under the name style as VECTOR SYSTEM.

With this new system, the brokers now need not assemble in the trading ring for execution of their orders. They can conduct the trading by sitting in their offices from which their computers are connected to the main computer of the Exchange through Local Area Network. The orders are compiled by the main system during trading hours and are matched by computers with the principle of "best bid is matched with the best order." The moment trade is matched, it is instantly informed to the members which he can visualise on his computer screen.

The system has also created transparency to the investors as far as the rates of the securities, the general market trend, liquidity etc. is concerned. The members are also benefited as far as their data regarding pending orders, day to day position about the business recorded is being generated expeditiously through the system.
