ae:@利用这一算法, 当我决定当天下午买进时，如大盘弱势和个股交易活跃, 有时可以借助'Pre-close Session' (闭市前时段) 以低一级的价位或插队抢先入货.,_wjWbN        o O6T

@T,a.Ceh8Q9mPU#Mwww.sgwritings.com Kg!qOEu
It is a 30-minute session before regular trading starts at 0900 hrs. It comprises the 'Pre-Open Period' and the 'Non-Cancel Period'.During the 'Pre-Open Period' (0830 to 0859 hrs), buy and sell orders can be entered, amended or withdrawn. They will not be matched and executed during this period. The 'Non-Cancel Period' is between 0859 to 0900 hrs, during which input, amendment and withdrawal of orders are not permitted. Orders that are matched are executed at a single computed price, which will be the same as or better than the price at which the orders are entered. This computed price shall be the opening price for the day. Unmatched orders will be carried forward into the regular trading session.
