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.

Global Variables work between different MultiCharts processes of the same bitness if they use the same GlobalVariable.dll (that is stored in the same place). Thus, it is possible to pass values between:
MultiCharts 32bit and MultiCharts 32bit
MultiCharts 64bit and MultiCharts 64bit
MultiCharts .NET 32bit and MultiCharts 32bit
MultiCharts .NET 64bit and MultiCharts 64bit
