New article Other classes in DoEasy library (Part 71): Chart object collection events has been published:
In this article, I will create the functionality for tracking some chart object events — adding/removing symbol charts and chart subwindows, as well as adding/removing/changing indicators in chart windows.
Compile the EA and launch it on a symbol chart.
Open a new symbol chart — get the following journal message from the OnDoEasyEvent() handler:
OnDoEasyEvent: Open chart: AUDNZD H4, ID 131733844391938634Add a new window of any oscillator to the open chart — get the following journal message from the OnDoEasyEvent() handler:
Add any indicator drawn in the main window to the open chart — get the following journal message from the OnDoEasyEvent() handler:
Change the oscillator parameters — get the following journal message from the OnDoEasyEvent() handler:
Change the indicator parameters in the main window — get the following journal message from the OnDoEasyEvent() handler:
Remove the oscillator window — get the following two journal messages from the OnDoEasyEvent() handler:
Remove the indicator from the main window — get the following journal message from the OnDoEasyEvent() handler:
Close the previously opened chart window — get the following journal message from the OnDoEasyEvent() handler:
OnDoEasyEvent: Closed chart: AUDNZD H4, ID 131733844391938634As we can see, all events are handled correctly and sent to the control program.
