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 on in the script calculation.
