sub_window=-1

[in]  Number of the chart subwindow. 0 means the main chart window, -1 means all the subwindows of the chart, including the main window.

[in]  Type of the object. The value can be one of the values of the ENUM_OBJECT enumeration. -1 means all types.

Note

The function uses a synchronous call, which means that the function waits for the execution of all commands that have been enqueued for this chart prior to its call, that is why this function can be time consuming. This feature should be taken into account when working with a large number of objects on a chart.

When an object is renamed, two events are formed simultaneously. These events can be handled in an Expert Advisor or indicator by the OnChartEvent() function:

• an event of deletion of an object with the old name;
• an event of creation of an object with a new name.
