Setting session templates for multiple symbols programmatically

[alex.nt]

Hello,

Is it possible to define/assign session templates per instrument via the code?

Actually, I would like to ignore pre/after market bars for all symbols in my strategy. How can I do that? Is session templates something I should use or there are better ways?

While there isn't a supported way to define session template via code you do have two supported options available to you.

Option 1: Implement a time filter: http://www.ninjatrader.com/support/h...tml?totime.htm
You can also use this to monitor the session info: http://www.ninjatrader.com/support/h...ml?session.htm

Option 2: Run the strategy from a chart that has the other series manually added. Doing this will force the individual templates to be used. This is further explained here in the "True Event Driven OnBarUpdate() Method" section: http://www.ninjatrader.com/support/h...nstruments.htm

Let me know if I can further assist.

There is another option that you have. You can select your preferred session template for each instrument under instrument settings. Then run your strategy with instrument settings.

However, changing instrument settings will also affect all other charts, if you select the session template <instrument settings> when adding a DataSeries.

Is there a way to change Session Template for a bunch of instruments without having to edit through Instrument Manager one by one?

Reimporting the symbols with a different Session Template doesn't seem to overwrite the old one.

There isn't a supported way to do this but it is possible.

With NinjaTrader closed you can go to Program Files (x86)\NinjaTrader 7\db and edit the instruments.txt file.

Please note this is unsupported and I will not be able to provide any further assistance with issues that may arise in this process.

Let me know if I can further assist.

Also wanted to add. The text file is only parsed when you reset the DataBase file's instruments

Tools -> options -> Data -> Reset instruments

I know this is an old thread, but it seems instruments.txt only contains symbols that come pre-loaded with NT.

Is there a text file for symbols that were user-added?

Thanks.

Hello nicbizz,

Thanks for your post.

No, any added instrument are internal (in the database file).

You can create a text file for added instruments and then import the text file. For example I have once created a text file for all Nikkei stocks and then imported it.
