Add a self-created price marker

[sidlercom80]

Hi, i would like to add a price marker to the line generated in onRender(), just like the orderlines in the charttrader. is this possible? how would i have to create the price marker directly in the strategy or a drawing tool or indicator? what would be the best solution for this? second question would be how to move the line with the mouse, i would like to recreate the same functions as in charttrader. maybe someone here has a tip on how I can best work on the implementation ;-)

Hello sidlercom80,

Thank you for your post.

I'd probably recommend using a drawing tool - the below Labeled Lines Drawing Tool add-on from our publicly available User App Share would be a good place to start:

If you want to make the label look different, you can use PathGeometry to make something that looks more like the Chart Trader price markers.

As far as capturing mouse events to create a click/drag functionality, that would be primarily out of the NinjaScript realm of support and more into C#, but there's useful information on this post that should help you get started:

Hi _Kate thank you for your post,

when the mouse pointer is in the rectangle and the left mouse button is pressed, an action is executed. that fits so far, but how can i prevent that when moving the mouse with pressed mouse button, the chart is not moved? is there something like chartControl.IsEnabled = false; that would work here? if the conditions are fulfilled, switch off chart moving ( chartControl.IsEnabled = false) and switch it on again with (chartControl.IsEnabled = true).

Hello sidlercom80,

Thank you for your reply.

There are no documented NinjaScript methods for this and this would require custom C# coding.

You might add a handler to the PreviewMouseDown event to detect the chart has been clicked on and instead of the default logic, execute your own logic for clicking and dragging.

Below is a link to an indicator example that uses this.
