TRADING SYSTEM
The Chittagong Stock Exchange was the first stock exchange in the country to introduce automated trading system on June 1999. The trading system at CSE known as CHITTRA connected major cities of Bangladesh enabling all members to trade nation wide simultaneously with ease and efficiency. CHITTRA provides a screen based, quote-driven trading facility. Investors are allowed to quote an expected price in their buy/sell orders. CHITTRA automatically matches the best prices.
Order Matching Mechanism
In terms of the matching process, there are two methods
1. Orders are sorted and matched with opposite orders of the best price. Waiting orders are automatically in the following sequence keeping the system fair and transparent:
* Best Price
* Within Price, by time priority.
The best buy order will match with the best sell order. The best buy order for a seller is the one with highest price and the best sell order for a buyer is the one with lowest price. An order may match partially with another order resulting in multiple trades.
2. Orders are queued for matching at a specified time at a single price.
Subsequent to matching, trade confirmations are sent to the respective workstations, which can be printed online. The system displays scrip and market related information required to support traders.
TRADING ORDERS
CSE trading system provides immense flexibility to the investors in terms of kinds of orders that can be placed to trade. The system allows the user to modify or cancel an order prior to execution.
The most frequently order on the CSE is the limit order, which is an order to buy or sell at a specific price. Conditions related to time can be easily made into a limit order, which are as follows
Good Till Cancelled (GTC): A GTC order is the order that remains in the system for a period not exceeding one calendar week or the member cancels it.
Good For Day (GFD): A GFD is the order, which is valid for the day on which it is entered. If the order is not matched during the day, the order gets cancelled automatically at the end of the trading day.
Good Till Date (GTD): A GTD order allows the member to specify the number of days not exceeding one calendar week for which the order shall stay in the stay in the system. At the end of this period the order shall be deleted from the system.
In addition to limit order, the Exchange has introduced other following types of orders for the investors

Minimum Fill: An order in which the minimum quantity must be filled.
