抱歉~小弟亂入解釋一下~>"<
我只是個有幾年期貨經驗的小咖....
以下的解釋是根據版友~D神跟我當營業員的朋友拼湊而來!
有誤請指正~並鞭小力一點~~>"<
關於幾位版友的爭論...其實一個在爭關於買方為何會負!
一個是搓合的問題~~其實T大想講的是搓合的問題
1.首先~~為何買到負?
這個D神有提出看法..請參照之前推文
總之...程式以當時的市價3.5*200去下單...
當然因為錢夠~~所以下的下去...
問題是...為何是負的?
原因在於"市價"單
市價就是以漲停價吃下市面上所有的單....(如果有漲停價的話)
(結果真的有人開漲停價 OTZ)
但重點來了~~市價單就是成交才回報....
所以當價格飆上了620...回報回去! 當然就變負了! @@
2.為啥沒有擋單?
可不可以每成交一筆就回去CHECK餘額呢?
我也問過我朋友這個問題....
我朋友說不可能!
因為其實券商只是前台~後台是送去期交所去搓合!
所以~~當你用市價下!程式以當時市價(3.5)或上下兩檔?(有人說10檔)
去算! 可以就送出去期交所了!
因此期交所收到是200口市價單!
而市價單是成交才回報~~所以....就是這樣~~~變負了!>"<
3.所以~~就是演變成今天的補漏洞!
沒有市價單了! 大家都用限價!
因此下單前的CHECK就會以你的"限價"來去CHECK你的餘額!
所以就不會有這問題了~~~ ^^"
以上~~希望有幫助!^^"
