The Exchange is open for continuous trading from Monday to Friday from 9.30 a.m. to 2.30 p.m.
The trading sessions are as follows:
|Open Auction Call||9:00 - 9:30||Monday - Friday (Except Public Holidays)|
|Regular Trading||9:30 - 14:30|
During Open Auction call (9.00 am to 9.30 am) the system accepts orders. These orders can be amended and cancelled during this session. However, no trades take place during this stage. Orders during this period are held in the ATS and will be forwarded to the execution engine at Regular Trading session, and at 9.30am the system starts matching orders according to the algorithm. It establishes the opening price and determines the orders to be executed according to the rules for the open auction callsession (Automated Trading Rule 4).
During regular trading (09.30 am to 2.30 pm) new orders are continually matched to existing orders in the order book. If an order cannot be executed, it is stored in the order book.
Market closes at 2.30 pm.
In the event the S&P SL20 Index (or the index that may replace the S&P SL20 in the future) drops by 5% within the day from the previous market day’s close, a “Market Halt” will be imposed on all equity securities for a period of 30 minutes. In case if the above scenario takes place at 2.00pm or later, the market will be halted and closed at 2.30pm. This is effective from 2nd January 2009. Market wide index based circuit breakers are imposed by stock exchanges to halt trading of equity securities in order to provide a "cooling off" period when there is an unusual movement in the index. Broker Firms may cancel any pending orders during the "Market Halt". However Broker Firms cannot enter new orders or amend pending orders during the "Market Halt".
