First Add On

[NinjaTrader_Matthew]

Thanks for the report, we'll have that fixed - NTEIGHT-8213

I'm attaching a sample addon made by NinjaTrader_Jesse which has some more thorough inline comments which may assist with creating a custom window and implemented the tab features, etc.

Please expect updates to our AddOn documentation in the next few weeks.

I could have swarn I tried adding this line:
using NinjaTrader.Custom;
using NinjaTrader.NinjaScript;

NT Support, this is missing from the ADDON template.

Thank you gregid.

EDIT: looks like 2 using statements are missing.

Thanks,

That didn't seem to resolve my issue "The type or namespace 'NTWindow' could not be found (....)".

I will have to wait for better documentation or an example.

gregid,

I keep getting errors with
NTMenuItem
NTWindow,

Is there a "using" you needed to add or is the On-Line instructions wrong?

The AddOn instruction is simply not complete, look here to implement NTWindow:

http://www.ninjatrader.com/support/helpGuides/nt8/en-us/index.html?ntwindow_class.htm

After implementing this you should be fine just commenting out the remaining offending code to get it work for the first time.

[NJA_MC]

I have just added my first AddOn - as a New menu item (see the screenshot).

This is really cool and already gives me plenty of new ideas for development!

Awesome, we're thrilled to offer this toolkit and are very eager to see what you guys are going to be able to do in this area!
