Indicator SampleStreamWriter not creating an output file

[Red_70]

Hi,

I'm trying to learn the basics of NinjaScript from sample scripts, and I'm currently working with the indicator SampleStreamWriter located in the NT8 online help guide at
NinjaScript > Educational Resources > Reference Samples > Indicator > Using StreamWriter
to write price data to a text file.

In my NinjaTrader 8 app I opened a chart using the simulated data feed, and it is correctly logging OHLC bars. I then opened the editor, loaded the SampleStreamWriter indicator, and clicked the Compile button. However, no file was created in my Documents/NinjaTrader 8 folder, which is the folder indicated by the editor intelliprompt when I mouse-over the text "UserDataDir" in the path specification.

So I added the statement

Print(NinjaTrader.Core.Globals.UserDataDir);

to my OnBarUpdate() block in an attempt to print the value of NinjaTrader.Core.Globals.UserDataDir, using the approach suggested in message #2 of the forum post

https://ninjatrader.com/support/forum/forum/ninjatrader-8/add-on-development/1054502-user-data-dir

but nothing was written to my output window, even though I set the default output using

PrintTo = PrintTo.OutputTab1;

My questions are:

1. How do I create the file of OHLC values that SampleStreamWriter should be writing?
2. Why is my Print() statement not writing output to my output window?

Thank you!

Hello Red_70,

Clicking compile does not run a script, it just compiles this into an assembly.

You will need to run the script on a chart by right-clicking the chart -> select Indicators -> select SampleStreamWriter from the Available list -> click add in the configured area -> click OK.

The script will write to file as it processed the data on the chart.
Prints will appear as the the script processed the data on the chart.

The script will create the file, you will not have to create it yourself.

Below is a link to a forum post with helpful information about getting started with NinjaScript and C#. Please watch the NinjaScript Editor 401 training video.

Chelsea,

Thanks so much; it seemed I was missing something obvious! I'll check out the training video :-)
