The use of "." in a variable name is no longer allowed in MQL syntax, because it is now part of the Object-oriented Programming syntax.

Identifiers

Identifiers are used as names of variables and functions. The length of the identifier can not exceed 63 characters.

Characters allowed to be written in an identifier: figures 0-9, the Latin uppercase and lowercase letters a-z and A-Z, recognized as different characters, the underscore character (_).The first character can not be a digit.

The identifier must not coincide with reserved word.
