ChartApplyTemplate() on different chart closes EA settings dialog – expected behavior?

[Eric Emmrich]

Hi,

I noticed that calling ChartApplyTemplate() on a different chart seems to close the EA properties dialog on the current chart.

Steps to reproduce:

1. Attach the test EA (code below) to Chart A

2. Open the EA properties dialog on Chart A within 20 seconds

3. The EA opens a new EURUSD chart (Chart B) and applies a template to it

4. The properties dialog on Chart A closes, even though the template was applied to Chart B

I would expect the dialog on Chart A to remain open since ChartApplyTemplate() targets a different chart. In MT4, the settings dialog remains open, as expected.

Tested on Version 5.0 build 5640.

Is this expected behavior or a bug? I couldn't find any documentation mentioning this side effect.

Test EA attached below.

Thanks for any clarification!
