各位前輩大家好,小弟剛踏入股海二個禮拜~
想請問一下現股當沖"做空"是怎麼執行呢?
我知道先買低後賣高的現股當沖要同一天完成,才無需成本。
因為還沒有實際操作過放空想請問一下再下手,避免大失血...
目前知道有兩種方式,一種是融卷賣出在融資買進,當日沖銷。
另一種是現股賣出,勾選賣出現沖,收盤前要現股買進回補來沖銷。
那假設今天我選牧德(3563)來放空,選擇現股放空方式如圖所示:

首先假設三種情況:
跌停415.8 現價462 漲停508.2
(1)今天我選擇賣出現沖488成交以後,盤中至收盤前以低於488的價格買進
理論上就是正損益沒錯吧?如收盤前高於488買進就是負損益囉,目前觀察在
13:25~13:30這5分鐘會出現試搓的小字樣,那我最後買進回補的時間是否要再
13:25前,還是這5分鐘到30分鐘間都可以下單買?要掛甚麼價格一定能買到呢?
(2)盤中漲至漲停價508.2(會鎖住?),那我有甚麼辦法以漲停價買進來回補呢?
(3)盤中跌至跌停價415.8,那我是否直接掛買就能買到來回補呢?
另一點請問如果當日沒回補會多付收盤價的10%?那隔天還能買進回補?
這是小弟目前的理解,不知是否有錯呢?還請各位高手來指導教學一下,謝謝囉。
