Specifiche

Technical Assignment: We need code (implemented as an expert) that creates a CComboBox object on a chart, in which the items reflect the current symbols from the Market Watch window and can be changed in the ComboBox. When a symbol is changed, the name of the symbol selected in the ComboBox should be written to the expert logs.

The code should be as simple as possible. It should avoid using classes and can use standard MQL5 includes.

The code provided in the MQL5 documentation example for the ComboBox adds the ComboBox to a dialog window and actively uses classes. The task is to simplify this as much as possible by avoiding the use of classes and the window in which the ComboBox is embedded.
