In the old cry-out system scrips are traded one at a time. Although trading hour last for few hours, practically one scrip gets only a few minutes to be dealt in. In the new computerized system, brokers workstations will allow traders to trade each and every scrip throughout the business hour.

The system will have four basic sessions:

Pre- opening : Only Limit order entry is permitted . No order will be executed in this session . Brokers will see only the previous day's closing price and index .

Opening :System will not be available for use during this session that will last for a few minutes only . The system will work alone to calculate the opening price for the day based on the orders input during the previous sessions.
Continuous Trading Hour :
This is for normal trading and will last for normal business hour . All types of orders will be accepted by the system during this period .

Closing Session : The system will stop receiving orders and will calculate the closing prices for each security . Pending orders " trade at closing price " will be matched during this session .

After the closing session the system will provide access to the trading members to make inquiry , verify and down load the daily relevant transaction details .

The system will also have sessions for Odd Lot , Spot and Auction sessions . These sessions however may take place simultaneously with the normal trading sessions . If brokers are interested to do trade in Odd Lot or are interested to see what stock is being sold and bought they will need to open the relevant windows only.
