This class provides MQL5 programs with the ability to easily detect changes within the Market Watch window. It monitors symbol sorting, additions, deletions, and changes to symbol sets. Additionally, it tracks the opening and closing of charts, as well as the availability of one-click trading on the active chart where the program is running.Also recommended: check for market open hours - similar library with strong performance on MetaTrader 5.
The class sends custom events to the control program to notify it of these changes.
Available public methods are detailed within the class implementation.
Custom events sent to the control program include:
- Market Watch changes (e.g., symbol added, removed, sorted)
- Chart events (e.g., chart opened, closed)
- One-Click Trading status changes
The identifier values can be correlated with standard identifiers or set at your discretion.
The values passed to the control program along with the event provide details about the specific change.
To integrate the class into your program, include the header file in the global scope and instantiate the class:
#include <achartsandmwclass.mqh>
CChartsMW mw;
Within your program's OnInit() function, add the class timer:
mw.Initialize();
Add the class event handler in OnChartEvent():
mw.HandleChartEvent(id, sparam, dparam, sparam_str);
Events returned by the class can now be accepted and processed in your program's OnChartEvent() function.
An example demonstrating how to receive events from the class is provided in the attached Expert Advisor, extestchartsmwclass.mq5.
