Code for Bar Creation on Charts

[RJay]

Where would I look to see the code used to generated the price bars for each of the types of charts available on NT? (Volume, Tick, Minute, etc.)

Thanks,

RJay

Hi rt6176, unfortunately this is not available. It is interally generated from the incoming tick / minute data by your broker or dataprovider.

For a custom chart style and its programming you can check the 'RangeAlt' chart style in our sharing - http://www.ninjatrader-support2.com/...nge+alt&desc=1

I did look at 'RangeAlt' cs file last weekend. It did have information that was useful.

I have another question. Is it possible to edit and compile this 'RangeAlt' cs file inside the NT platform?

I could not figure out how to do it. Its not an indicator or a strategy?

Thanks,

RJay

No, it is a chart style.

You can open it in any text editor, such as notepad.

Changes and modifications to it are unfortunately not supported by us.

Is there any supported or unsupported way to create new bar charts with NT?

rt6176,

Unfortunately this endeavour is outside the scope of what we can offer support for. You can try and see how RangeAlt did it, but we cannot offer you any guidance on this. Thank you for understanding.

Hi rt6176,

NT does not seem to support editing type files. I simply take a built-in class from Documents\NinjaTrader 6.5\bin\Custom\Type\@BarsTypes.cs as a template and change it to my new class in an external editor. Then i zip it (do not forget the Type/ directory) and import to NT as any indicator/strategy. It sounds complicated but it is rather straightforward.

Unfortunately, one is limited by BarsType class - which is storing only OHLCTV.

I encountered one problem with forms when having multiple custom bars, see

Hey Tomas,

I am trying to make a BarsType in NT. I have been using Renko bars which was posted by roonius a few days ago as my template.

As a first attempt, I didn't change anything in the code except for the name of the bartypes (anywhere I saw Renko I put test), and saved the files as test.cs. After I put it into a "Type/" directory and .zipped it up. I'm getting the following error...

Import failed. NinjaTrader could not decompress the NinjaScript Archive File: Could not find part of the path 'C:\Documents and Settings\Anthony\My Documents\NinjaTrader 6.5\bin\Custom\Tmp\Import\Type\'.

Have you encountered this?

Thanks for your help.

Anthony,

Drop the cs file in the appropriate file path and just open up any indicator and press F5 to compile.

Thanks for the help Josh

Hi mrlogik,

just a side comment: what Josh suggests is much more straightforward than what i did (importing code via zipped archive and using import ninjascript function). An interesting point is that, during compilation, NT recompiles all modified scripts - i.e. not only indicators and strategies but all the other stuff as well.

Hi Tomas,

I did try the RangeAlt,
but it cannot add in strategy timeframe:

Add(PeriodType.RangeAlt, 4);

any idea, thanks!

wkmetal,

Please use the IntelliSense on PeriodType and see what is available.
