Custom BarType bars

[Zeos6]

Is it possible to add custom parameters to the custom bar type?

Currently I am trying to create Renko bars built from points (double) rather than tick (integer) but there doesn't seem to be a way to do it - that I am aware of, at least. If any one knows how this can be accomplished, I would be most appreciative to hear. Thanks.

Hello Zeos6,

Thank you for your note. Custom properties are not currently possible with bar types. I will submit a feature request on your behalf to allow custom BarType / ChartStyle properties.

There is an undocumented workaround to re-use existing properties in these type of scripts.
Below is a link to a thread that goes into further detail.

Thanks for the reference ChelseaB but it doesn't really address the issue I was raising. I think that custom bar types without custom properties are really not all that useful. This feature really is needed badly. I am surprised that it was omitted.

Hello Zeos6,

Thank you for your response.

This feature request has been assigned the id SFT-1269.

Please let me know if you have any questions.

It may not be officially supported but I used the following in one of my custom bars for a custom property:

[NinjaScriptProperty]
[Range(0, int.MaxValue)]
[Display(Name = "Volume divisor", Description = "Volume divisor", Order = 2, GroupName = "Parameters")]
public int VolumeDivisor { get; set; }

Bit of a work around but worth exploring a bit. Thank you.

I'm not sure why you call it a work around, this is the way custom bars and chart styles define UI settable properties, decorate with the [NinjaScriptProperty] attribute.

Take a look at the existing bar types.

There is no intent to be disrespectful on my part.
Did you use that code in a custom bar type or in a chart style?

Sure, I used it in both custom bar and custom chart. That's what the built in bar types and charts use, check out the source.
