Drawing horizontal lines on multiple charts

[slouw]

Hi there
I presume this is the right place to make such a post and that if not someone will let me know thank you for that.
My question is, is it feasible to do the following programatically.
Create a hoz line on a given chart (call it the source chart) and give it a unique tag
Copy/past/recreate/attach that line on all charts for the same pair with a timeframe the same or smaller TF than the source chart.
For example I have a workspace with 9 tabs.
Each tab have a chart of a forex pair say GBPUSD with a progressively smaller TZ starting at 1Month then 1W/1D/4H/1H/30m/15/5m/1m
Let the 1H chart be the source chart.
I create a hoz line on this 1H chart.
I then the script to recreate/attach that hoz line on the 4 charts with smaller TF (30m/15m/5m/1m)

There is a feature built in where a hoz line can be set to be drawn on all charts
(Drawing Objects > Hoz Line Properties > General > Attach to > GBPUSD (All charts)

So such a script would be a variation on this.
I want a line to be attached to all charts with smaller TF than the original.
Hope this makes sense.

Can this be done within the NT8 development environment?

Thank you for any replies

Hello slouw,

Thank you for your note.

The ability to filter which charts will display a global drawing object is not supported but may be possible.

A possible solution may be to create an indicator which will write to a file the price of a horizontal line that is drawn. Then in another indicator you could read this file, and if the file contains a horizontal line to draw and the charts current interval is greater than x value, draw a horizontal line on the at chart.

I suggest seeing the following,
