Changing Global Object Properties

[Unsuitable]

Hello,

A bunch of the indicators offered by Ocean Trading Indicators interact with Draw Objects. Some objects are global objects. When changing the properties of global Draw Objects, only the objects on the current chart are changed.

How does one refresh charts globally?

Best regards

Hello Unsuitable,

Note, this does not affect manually drawn objects, which automatically propagate changes to other charts.

See this example that uses undocumented code to propagate changes to other instances of global drawing objects.

Hello NinjaTrader_ChelseaB,

Thank you for forwarding the link. If I understand correctly, lines 222-245 would go through all charts to find a specific type of drawing tool. In my case, find a chart object with a specific tag would work. Then update those values. Could also go through charts that only have the same instrument as well to cut down on processing power.

I noticed the drawing states are modified often. This may be a major oversight, but is that important when changing the visual properties of an object? The documentation on the Drawing States only mention the anchors, nothing about the properties such as color and thickness,

Best regards,

Hello Unsuitable,

Global Drawing Objects will only appear on charts of the same instrument.

The DrawingState is linked specifically to the anchors. When the object is first drawing its building and the clicks place the anchors. When editing this means the object is selected so an anchor can be moved. When moving this means an anchor is being moved.

The visual properties are not changing during these times.

Hello Chelsea,

Gotcha, thank you for the clarification.

To confirm, to propagate global object changes that an indicator does, the code has update the object manually on each chart.

I noticed that just moving the object will force update the changes to other charts.

Also simply copying the object after the update would propagate the changes globally.

Hello Unsuitable,

The DrawingToolContextMenuExampleIncreaseDecreasePrice example is looping through NinjaTrader.Core.Globals.AllWindows and getting all objects on all ChartControls.

Are you reviewing the code of this and finding this is not suffiecient for your needs.

Hello Chelsea,

The code loops through the charts but not tabs if that makes sense. I may be missing something, but it only returns the active chart. Referencing lines 222 to 243 and specifically line 235. This only retrieves the active ChartControl. I also posted a question about looping through tabs, and Emily redirected me to another thread. That should work.
