csv - 如何将 CSV 文件中的股票数据读取到 netlogo 中？

Question

我想将股票历史数据加载并读取到netlogo中，我发现how to read a .CSV file with netlogo非常有帮助。

但是，为了实现我所需要的，我仍然需要进入fileList的每个元素列表(参见上面的链接)，并提取元素列表的每个元素并将它们存储到不同的列表中如dates、openPrices、highPrices等。

谁能告诉我如何实现它？或者指出一些代码示例也非常有帮助。我刚刚开始学习netlogo，所以还有很多东西需要补。

非常感谢!

股票历史数据如下所示

2015/12/15, 12, 12.9, 11.99, 12.5, 10000

2015/12/16, 12.1, 13.9, 11.99, 12.8, 11000

globals[eachLine dates openPrices highPrices lowPrices closePrices volumes]

to openFile
  file-open "jqr.txt"
  set dates []
  set openPrices []
  set highPrices []
  set lowPrices []
  set closePrices []
  set volumes []

  set fileList []

  while [not file-at-end?] [
    set csv file-read-line
    set csv word csv ","  ; add comma for loop termination 

    let mylist []  ; list of values 
    while [not empty? csv] 
    [
      let $x position "," csv 
      let $item substring csv 0 $x  ; extract item 
      carefully [set $item read-from-string $item][] ; convert if number 
      set mylist lput $item mylist  ; append to list 
      set csv substring csv ($x + 1) length csv  ; remove item and comma 
    ] 
    set fileList lput mylist fileList
  ]

  ;; ??????
  foreach fileList 




  show fileList
  file-close
end
