DrawinTools -> accessing another DataSeries (for Tick Data)

[artson]

Hi,

I've been trying to add a "AddDataSeries" at OnStateChange() from a DrawingTool, but I get the error:
"AddDataSeries" doesn't exist.

I've read another post (https://ninjatrader.com/support/foru...ingtools/page2) but I still have it not clear.

I want to access Tick DataSeries with a DrawingTool, so I cant acces tick data only in the area I want (this will be defined with my drawingtool) and do my calculations.


Do you have any tips to do it?
I tried to read the mentioned post, but I cannot follow it perfectly.

Thanks in advance!

So, with more details, I want to acces Delta values from the bars, but within a DrawingTool......

When I try to read the "OrderFlowCumulativeDelta"

inside "OnRender"

I get the error:
Name "OrderFlowCumulativeDelta" not known.....

Hello artson,

Drawing tools scripts do not have a primary series and cannot add a secondary series. For this reason drawing tools do not have OnBarUpdate, OnMarketUpdate, or any other data driven methods.

It is not supported to call an indicator from a drawing tool (as there is no primary series).

You would have to do all calculations (that are done in the indicator) with custom code.

Thanks Chelsea, but how can I do the calculations, if I cannot acces to de Delta data?
How can I access from a i.e. 10 minute Chart to the information from OrderFlowCumulativeDelta (or from Volumetric Bars)??

Hello artson,

This would not be possible specifically with Order Flow scripts as these are proprietary and not open source. The calculations would have to be your own.

Are you certain what you are wanting to do cannot be achieved with an indicator?

Hi,

With an indicator I cannot select an specific area where I want to read the Delta.
With an indicator I read a complete Day, or X bars, or whatever....

If I use a Drawing Tool I can select only the area I want (for example in a lateral area I could see supports and resistances and see what Delta is doing and who is winning the battle.....

Hello artson,

With an indicator you can click on the chart twice and get two points on the chart. What specifically is stopping you from selecting a specific area?

With an indicator you could get the anchor points of a manually drawn rectangle as well.

With that said, this may not be something possible with NinjaTrader Drawing tools as these do not support calling an indicator.
