Every transaction in the stock exchange is carried out through licensed members called brokers.
To trade in shares, you have to approach a broker However, since most stock exchange brokers deal in very high volumes, they generally do not entertain small investors. These brokers have a network of sub-brokers who provide them with orders.
The general investors should identify a sub-broker for regular trading in shares and palce his order for purchase and sale through the sub-broker. The sub/broker will transmit the order to his broker who will then execute it.
What are active Shares?
Shares in which there are frequent and day-to-day dealings, as distinguished from partly active shares in which dealings are not so frequent. Most shares of leading companies would be active, particularly those which are sensitive to economic and political events and are, therefore, subject to sudden price movements. Some market analysts would define active shares as those which are bought and sold at least three times a week. Easy to buy or sell.
