Where Are All The Shared ChartStyles

[PaulMohn]

Hi, i'm looking to see if there is some sort of FileSharing page for ChartStyles, similar to the User App Share for Indicators and Strategies


I'd like to check if there is a NT8 version of this NT7 ChartStyle version
https://ninjatrader.com/support/foru...969#post725969
Else I'll try and convert it although it is challenging with the SharpDX requirement in NT8.
or could someone tell if we could convert it without SharpDX? Thanks

Hello PaulMohn,

Thanks for your post.

Unfortunately, there is no specific site or section of the forums pertaining to specifically finding custom ChartStyles.

You may find some custom ChartStyles in the User App Share center. Otherwise, you would need to convert the script in question to be compatible with NinjaTrader 8.

If the script in question uses SharpDX, it is likely that SharpDX would need to be used when converting the script to NinjaTrader 8.

This thread will be open for other community members to share their insight on this topic.

Below I am including a link to a list of the code-breaking changes from NinjaTrader 7 to NinjaTrader 8. The help guide page will be the best way to see how things have changed from NinjaTrader 7 to NinjaTrader 8.

Below is a link to a forum post with helpful information about getting started with NinjaScript.

Hello Brandon and thanks for the reply and info. The tricky part is that the ChartSyle Code does not uses SharpDX (NT7), but the similar NT8 ohlcStyle Chart (built in NT8) does use SharpDX.

Here's the NT7 Code for quick reference:

Can it be converted without using SharpDX?

Hello PaulMohn,

Thanks for your note.

If you are wanting to modify the OHLC ChartStyle in NinjaTrader 8, you could create a copy of the OHLC ChartStyle script in a NinjaScript Editor window and make the modifications to the script that you are wanting. Since the NinjaTrader 8 version of the OHLC ChartStyle uses SharpDX, you would need to use SharpDX when modifying the OHLC ChartStyle in NinjaTrader 8.

You would also likely need to use SharpDX in NinjaTrader 8 when converting the script from NinjaTrader 7 to NinjaTrader 8.

Note that to contact a specific forum user, you could click on the 'Messages' drop-down menu in the top right of the forum page and select 'Send new message'. Then input the username of the person you are wanting to contact.

I'd love to see a section for user shared chart styles!

[PaulMohn]

Thanks a lot Brandon for the "messages" info. I've sent one to the OP.

Just an aside question. I haven't very good eyes anymore and I've been wondering for a long time if there is a way to paste code with intact format into Ninjatrader Forum. I've tried several ways but it always displays the code without the easily readable formatting. For short snippets it's somewhat ok to get the code tabulated by hand but not for longer code. How do you get it to paste with preserved formatting? Thanks

Added note: I'm aware of beautifier tools, but for some reason I usually get the code adulterated with them and then get compile errors in the NinjaScript Editor.

Brilliant idea!

[NinjaTrader_BrandonH]

Hello PaulMohn,

Thanks for your note.

Unfortunately, there are no options available that preserve the formatting of code when copy/pasting code into the NinjaScript Editor window. The code's format would need to be manually modified after pasting.

We are currently tracking interest in this feature and your vote has been added. The internal tracking number for your feature request is SFT-3502. Please reference this internal tracking number when contacting Platform Support if you ever have questions regarding this feature request.

When a feature request is implemented, you'll find a description of the new feature in the release notes:

[PaulMohn]

Ok thanks Brandon for the answer. I think it would be great to use an other code pasting online app which preserves the formatting, or request pasters to share txts or .cs file as attachment (to avoid the adulteration of code problem).

samsonli, here are the User App Share currently returned ChartStyle when searching "ChartStyle" (but others as the one from post one above are missing)

https://ninjatraderecosystem.com/user-app-share-results/?fwp_usa_search=chartstyle

it would be helpful to gather all shared ChartStyles under a common section, to first see what has already been done and not recode it if not necessary.

[PaulMohn]

Hello Brandon,

Do you have some commented/annotated versions of the NT8 built in OhlcStyle and the CandleStyle ChartStyle scripts?

I've found some helpful (with examples) doc about

PaintBars (NT7 to NT8 Conversion)
https://ninjatrader.com/support/foru...212#post678212

rectangle F
https://docs.microsoft.com/en-us/dot...system-single)

?? and ??= operators (C# reference)
https://docs.microsoft.com/en-us/dot...scing-operator

C# Ternary Operator (?: ) with Example
https://www.tutlane.com/tutorial/csh...-with-examples

But there are still many things difficult to follow. I can't find examples and info related to the ChartStyle codes in the SharpDX doc and there's no commenting in the ChartStyle Scripts.

Using SharpDX for Custom Chart Rendering
https://ninjatrader.com/support/help..._rendering.htm

[NinjaTrader_BrandonH]

Hello PaulMohn,

Thanks for your note.

You could view the OhlcStyle ChartStyle and the CandleStyle ChartStyle that comes default with NinjaTrader in a New > NinjaScript Editor window.

To do so, open a New > NinjaScript Editor window, open the ChartStyle folder, and select the ChartStyle script you would like to view the code for.

Note that we do not have any other examples available for OhlcStyle or CandleStyle ChartStyles.

If you would like to modify one of those ChartStyle scripts then you could make a copy of the script. You could open the script you want to modify in the NinjaScript Editor window, right-click in the script, and select 'Save As' to make a copy of the script. Then that copy could be modified.

For more information about working with SharpDX, please see the SampleCustomRender indicator script that comes default with NinjaTrader. This script contains comments regarding using SharpDX in a custom NinjaScript.
