Text FIle Read/Write not working

[ginx10k]

Hello, I've downloaded the sample ReadWrite file. but since I didn't know where the program was creating the Text file. I changed the path. I still can't see any new file. Any idea how to make a simple path to write a text file to the Desktop of windows? I tried

 path = NinjaTrader.Core.Globals.UserDataDir + @"C:\Users\DG_Mobile_PC\Desktop\MyTestFile.txt" ;

and I tried [CODE] path = @"C:\Users\DG_Mobile_PC\Desktop\MyTestFile.txt" ; /CODE].

Hello ginx10k, thanks for posting.

NinjaTrader.Core.Globals.UserDataDir is a string resource that points to the Documents/NinjaTrader 8 folder, so if you want the path to go to the desktop just use:

path = @"C:\Users\DG_Mobile_PC\Desktop\MyTestFile.txt" ;

ChriL. Thanks for reply, I finally got the file to write. However, I just need help with one more thing. If you look at the attached file. I keep getting an error, about accessing a OnBarUpdate method on bar 0. I'm just trying to write the previous Day's Close to the text file. Any help is appreciated.

Hi, thanks for the follow up. The CurrentBar check is not correct, it should return if CurrentBars[1] is < 1

if(CurrentBars[1] < 1)
return;

//rest of OnBarUpdate.

Hi Chris. I got the indicator to write the proper Close of day to a file. Can you help me with one last thing. How do I turn a String into a Double? or should I say. If I want another indicator to read the text from the File, I'd like to take that "String" that it reads, and plot a Line using the numbers (daily close)

Hi, ginx10k

There is a Double.Parse method you can use:
