Question

我试图使用最简单的代码使用IBrokers包，如下所示：

library(IBrokers)

tws <- twsConnect()

aapl.csv <- file("AAPL.csv", open="wa")

# run an infinite-loop ( <C-c> to break )
reqMktData(tws, twsSTK("AAPL"), 
        eventWrapper=eWrapper.MktData.CSV(1), 
        file=aapl.csv)

close(aapl.csv)
close(tws)

我收到此错误：

2 1 321 Error validating request:-'oc' : 
cause - Incorrect generic tick list of 100,101,104,106,165,221,225,236. 
Legal ones for (STK)

一切都挂起......

我在这里做错了什么？任何分辨率或指向参考的想法都受到高度赞赏。

错误表明您的勾选列表很糟糕。如果将它与它报告的有效值进行比较，你会发现221是罪魁祸首。值得庆幸的是，?reqMktData告诉我们您可以使用tickGenerics选项指定自己的勾选列表。所以只需做一些像

这样的事情

> reqMktData(tws, twsSTK("AAPL"), 
         eventWrapper=eWrapper.MktData.CSV(1), 
         file=aapl.csv, tickGenerics="100,101,104,106,165,225,236")

你应该好好去。
