在 VBA 中,选择工具 > 参考并选择以下参考:
- 微软脚本控制 1.0
- Microsoft 脚本运行时
以下函数将检索特定交易品种的最新数据(开盘价、最高价、最低价、收盘价和成交量):
Public Function GetLastCloseData(symbol As String) As Dictionary
Dim scriptControl As Object
Dim json As Object
Dim time_series As Object
Dim date_data As Object
Dim date_label As String
Dim date_offset As Integer
Set scriptControl = CreateObject("MSScriptControl.ScriptControl")
scriptControl.Language = "JScript"
'Retrieve historical price data in JSON format
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=" & symbol & "&apikey=" & API_KEY, False
.send
Set json = scriptControl.Eval("(" + .responseText + ")")
.abort
End With
'CallByName returns an error if it cannot find the requested selection.
'The code is written to skip over those errors.
On Error Resume Next
Set time_series = CallByName(json, "Time Series (Daily)", VbGet)
'If time series property was found...
If Not time_series Is Nothing Then
date_offset = 0
'Retrieve the most recent closing price by looking for todays date. If it's not found,
'iterate through the last week of dates, stopping whenever the most recent is found.
While date_data Is Nothing And date_offset < 8
date_label = Format(DateAdd("d", -date_offset, Date), "yyyy-mm-dd")
Set date_data = CallByName(time_series, date_label, VbGet)
date_offset = date_offset + 1
Wend
End If
If Not date_data Is Nothing Then
Set GetLastCloseData = New Dictionary
With GetLastCloseData
.Add "Open", CDbl(CallByName(date_data, "1. open", VbGet))
.Add "High", CDbl(CallByName(date_data, "2. high", VbGet))
.Add "Low", CDbl(CallByName(date_data, "3. low", VbGet))
.Add "Close", CDbl(CallByName(date_data, "4. close", VbGet))
.Add "Volume", CLng(CallByName(date_data, "5. volume", VbGet))
End With
End If
'set error handling back to normal
On Error GoTo 0
End Function
以下 Sub 演示了如何使用结果:
Public Sub GetStockData()
Dim daily_data As Dictionary
Set daily_data = GetLastCloseData("SPY")
Debug.Print daily_data("Open")
Debug.Print daily_data("High")
Debug.Print daily_data("Low")
Debug.Print daily_data("Close")
Debug.Print daily_data("Volume")
End Sub
输出:

260.15
