[發問] 如何使用巨集自動計算股價漲跌停價?

shuasa

請問要如何用使巨集自動計算股價票漲跌停價?

jackyq

大大應該先舉例說一下
哪一日的值計算有錯誤
而正確的值應該又是多少

    我原本是用儲存格用函數公式套用,如4/6日的漲停價是4/1日的收盤價套上公式
   M14儲存格的公式是 =IF(F15="","",FLOOR(F15*1.1,LOOKUP(F15*1.1,{0,10,50,100,500,1000},{0.01,0.05,0.1,0.5,1,5})))

漲停價公式
=FLOOR(A1*1.1,LOOKUP(A1*1.1,{0,10,50,100,500,1000},{0.01,0.05,0.1,0.5,1,5}))
跌停價公式
=CEILING(A1*0.9,LOOKUP(A1*0.9,{0,10,50,100,500,1000},{0.01,0.05,0.1,0.5,1,5}))

但是如何用巨集的方式呈現?

大大我照你公式翻譯而已

Public Function 漲跌停價(昨收,  漲or跌 As Long)

漲跌停價 = ""
If 昨收 = "" Then Exit Function

   Price_Sample = Array(0, 10, 50, 100, 500, 1000)
interval_Sample = Array(0.01, 0.05, 0.1, 0.5, 1, 5)

interval = Application.WorksheetFunction.Lookup(昨收, Price_Sample, interval_Sample)

If 漲or跌 > 0 Then 漲跌停價 = Application.WorksheetFunction.Floor(昨收 * 1.1, interval)
If 漲or跌 < 0 Then 漲跌停價 = Application.WorksheetFunction.Ceiling(昨收 * 0.9, interval)

End Function

    感謝jackyq大大指教,讓我又多學到知識:)

應用 jackyq  大大的函式稍加修改如下，
參考一下：

1. Public Function UpDown(ud As Range, Optional UpDn As Boolean = True)
   
2.     If ud.Value = 0 Then UpDown = 0: Exit Function
   
3.       
   
4.     Price_Sample = Array(0, 10, 50, 100, 500, 1000)
   
5.     interval_Sample = Array(0.01, 0.05, 0.1, 0.5, 1, 5)
   
6.          
   
7.     interval = Application.WorksheetFunction.Lookup(ud.Value * IIf(UpDn, 1.1, 0.9), Price_Sample, interval_Sample)
   
8.     UpDown = Application.WorksheetFunction.Floor(ud.Value * IIf(UpDn, 1.1, 0.9), interval)
   
9. End Function

漲停價函式
=UpDown(F8)
等於
=UpDown(F8,1)
等於
=UpDown(F8,True)

跌停價函式
=UpDown(F8,0)
等於
=UpDown(F8,False)

亦可直接以 VBA 程式段來處理：

1. Sub Ex()
   
2.     Dim xVal As Double
   
3.    
   
4.     xVal = UpDown([F8])
   
5.     MsgBox "UpDown([F8]) (漲停價) = " & xVal
   
6.     xVal = UpDown([F8], 1)
   
7.     MsgBox "UpDown([F8], 1) (漲停價) = " & xVal
   
8.     xVal = UpDown([F8], True)
   
9.     MsgBox "UpDown([F8], True) (漲停價) = " & xVal
   
10.    
    
11.     xVal = UpDown([F8], 0)
    
12.     MsgBox "UpDown([F8], 0) (跌停價) = " & xVal
    
13.     xVal = UpDown([F8], False)
    
14.     MsgBox "UpDown([F8], False) (跌停價) = " & xVal
    
15. End Sub

我有理解錯歐     

應該這樣才對

Public Function 漲跌停價(昨收,  漲or跌 As Long)

漲跌停價 = ""
If 昨收 = "" Then Exit Function
if 漲or跌 = 0 Then Exit Function

   Price_Sample = Array(0, 10, 50, 100, 500, 1000)
interval_Sample = Array(0.01, 0.05, 0.1, 0.5, 1, 5)

漲跌停價 = 昨收 * ( 1 + sgn( 漲or跌 )   )  * 0.1
interval = Application.WorksheetFunction.Lookup(漲跌停價, Price_Sample, interval_Sample)

If 漲or跌 > 0 Then 漲跌停價 = Application.WorksheetFunction.Floor(漲跌停價 , interval)
If 漲or跌 < 0 Then 漲跌停價 = Application.WorksheetFunction.Ceiling(漲跌停價 , interval)

End Function

跌停一定要用 Ceiling 不能用 floor

挖哩勒 !!!!  0.1 放錯位置

再更正一次

Public Function 漲跌停價(昨收,  漲or跌 As Long)

漲跌停價 = ""
If 昨收 = "" Then Exit Function
if 漲or跌 = 0 Then Exit Function

   Price_Sample = Array(0, 10, 50, 100, 500, 1000)
interval_Sample = Array(0.01, 0.05, 0.1, 0.5, 1, 5)

漲跌停價 = 昨收 * ( 1 + sgn( 漲or跌 )  * 0.1  )  
interval = Application.WorksheetFunction.Lookup(漲跌停價, Price_Sample, interval_Sample)

If 漲or跌 > 0 Then 漲跌停價 = Application.WorksheetFunction.Floor(漲跌停價 , interval)
If 漲or跌 < 0 Then 漲跌停價 = Application.WorksheetFunction.Ceiling(漲跌停價 , interval)

End Function
