All transactions are in cash, and they are performed on the exchange.
Orders are entered into the system by stock exchange representatives, who are supplied with code numbers for that purpose. Orders are entered either from the floor of the exchange or from the offices of the members, by means of remote broking operations. Each member-brokerage firm is allowed to have up to six terminal stations, the use of which is restricted to the trading hours of the stock exchange. All transactions introduced into the system before 10.00 a.m can participate in the formation of the opening price. At the pre-opening period, the system accepts limit and market orders.
