Use SAPIEN PowerShell Studio to protect your Nintendo Stock Gains

Thanks to a lot of press, Pokémon Go raised Nintendo’s stock price by over 30% Today.  Unfortunately, you may not be able to set a stop loss on it to protect those gains because it is traded on a foreign stock market.  In this post, we will use SAPIEN PowerShell Studio 2016 to create a small GUI to alert us should the stock fall below a specified price.


First off, create a New Form Project.


Next you will need to create a form using 3 labels and 2 text boxes. Set the name of the first text box to Textbox_Symbol and the second to Textbox_Low  for the fourth label, set the name to Label_Price.  The names of the other form controls do not matter for this exercise.

Pre-populate the value of Symbol with NTDOY.  Also pre-populate the value of Low with your selling price.

Also add a Timer control and leave the default settings.

In the script tab, replace the code with what is below.
$MainForm_Load={
  $timer1.Interval = 5000
       $timer1.Start()
}



$timer1_Tick={
       # Set the refresh for 5 minutes.
       $timer1.Interval = 300000
      
       function Get-StockInfo
       {
             
              $Sym = $textbox_Symbol.Text
              $URL = "http://finance.yahoo.com/d/quotes.csv?s=$Sym&f=snl1ghjk"
             
              $Obj = New-Object -TypeName PSObject -Property @{
                     Ask = $Null
                     DayLow = $Null
                     DayHigh = $Null
                     YearLow = $Null
                     YearHigh = $Null
              }
             
              $Data = Invoke-RestMethod -Uri $URL
              $Data = $Data.Replace("N/A", "NA")
              $Obj.Ask = ($Data.Split(","))[2]
              $Obj.DayLow = ($Data.Split(","))[3]
              $Obj.DayHigh = ($Data.Split(","))[4]
              $Obj.YearLow = ($Data.Split(","))[5]
              $Obj.YearHigh = ($Data.Split(","))[6]
             
              $label_Price.Text = $Obj.Ask
              If ($Obj.ask -gt $textbox_Low.text) {$label_Price.BackColor = 'Green'}
              Else { $label_Price.BackColor = 'Red'}
             
       } # END: function Get-StockInfo
      
       Get-StockInfo
}#end timer1_Tick


Here is the end result.

Not much, but if the price drops below $27.00, the price turns red.  This is just a basic example of how to create a GUI with SAPIEN PowerShell Studio 2016.  I encourage you to download the trial edition. You can down load it from here:

Remember that this is an alert from data that is about 10 to 20 minutes old.  You will also have to trigger the sell manually.  This is just a demo to show you the possibilities of using SAPIEN PowerShell Studio 2016 and not an actual stock trading tool.

Nice example, thanks! You can simplify the code by using CovertFrom-Csv for the custom object creation replacing 12 lines of code with:
$Obj = $Data.Replace("N/A","NA")|ConvertFrom-Csv -Header Symbol,Description,Ask,Daylow,DayHigh,YearLow,YearHigh
