Understanding Global Variables
Global Variables is an external .dll file that can be used to pass values between strategies on separate charts and third party applications.
The information is stored in a shared memory space. External processes can access the data in the memory for further operations.
From Multicharts, the Global Variables functionality is accessed by PowerLanguage functions.
When a customer uses Global Variables it is important to determine the read-write action time because the actions are performed in the script calculation.
