我看了HK - Trading in Hong Kong - TWS BookTrader-20090114 0829 的這段影片後
中有提到 這兩個用法
when B/A Size column is clicked at an empty price level and there is already an existing
. move existing order
. create new order
when B/A Size column is clicked at a price level that already has an existing order
. cancel order
. create new order
影片中分為幾次的說明 第一次 上面選move existing order + 下面選create new order
然後在一個空白Bid size那邊點兩下 出現3口單(包含一開始的第一口)
然後在選move existing order + cancel order 就只要點一下就可以取消3口單
