Global Variables of the Client Terminal

There is a group set of functions for working with global variables.

Global variables of the client terminal should not be mixed up with variables declared in the global scope of the mql5 program.

Global variables are kept in the client terminal within 4 weeks since the last access, then they will be deleted automatically. An access to a global variable is not only setting of a new value, but reading of the global variable value, as well.

Global variables of the client terminal are accessible simultaneously from all mql5 programs launched in the client terminal.

Function	Action
GlobalVariableCheck	Checks the existence of a global variable with the specified name
GlobalVariableTime	Returns time of the last accessing the global variable
GlobalVariableDel	Deletes a global variable
GlobalVariableGet	Returns the value of a global variable
GlobalVariableName	Returns the name of a global variable by it's ordinal number in the list of global variables
GlobalVariableSet	Sets the new value to a global variable
