Export chart data to file

[Grantx]

Sierra Charts has this very useful ability to export chart data to a text file. So as an example, if I have the chart configured with 47 minute bars real trading hours only - it can export the OHLC data of each bar out to a file. Please tell me ninjatrader can do this...

Included is a link which contains a script that will allow you to do exactly what you have described.

But actually StreamWriter shouldn't even be necessary for OHLC values, only indicator and other calculated values. If you simply want to upload price data, you can go to Command Center > Tools > Export > Historical Data

Cool. Thank you. The reason I need this is because I only want to load session specific bars, not the entire data history.

What do I do once I have loaded the indicator? I can see it in the indicator panel below and it says 'sample stream writer' but then what? Has it created the file already (where do I find it?)or do I need to do something further?

Not sure what OS you are using, but in windows you would go to File Explorer > Documents > Ninjatrader 8, and you should see a new file called "MyTestFile" assuming you did not change the name in the indicator script. Good Luck!

P.S. reloading this indicator repeatedly or loading a large amount of data can be CPU intensive, so try to be conservative about what you use it for.

Thank you so much lunardiplomacy
That is exactly what I was looking for.

I'm testing this indicator. When applied to the first chart, it worked perfectly. Any next instance doesn't write to the file. How to I apply it to retrieve a new data set?
