Hello, I know you folks would have tons of feature requests but I would like to add one to your queue :). It would be very useful to have an API supported Global/Chartbook level cache accessible via ACSIL? It will take away the dependencies that gets created between charts in a chartbook when there is a need to share persistent variables between multiple charts. I have ended up in cyclical dependencies in the past and the work around I used was have duplicate chart of same type. Thank you! J Date Time Of Last Edit: 2026-02-24 20:19:36

Not sure that we understand exactly what you need. Since a custom study is a C++ function, you could always declare variables in the global scope, outside of a function, which will be globally accessible from any study function. These will persist, during the entire running session of Sierra Chart. Unless the Custom Study DLL gets unloaded but that will not normally happen unless a custom study is being rebuilt.

backinblack , maybe "named memory mapped files" could be useful for your scenario.
