Is is possible to get access to the "SCStudyInterfaceRef sc" object from inside a thread? This "SCStudyInterfaceRef sc" object is passed to the SCSFExport functions within the study... but I would like to get access to it from a thread that is running on a timed interval. For example... void ReadPositions() { SCStudyInterfaceRef sc = // How to access it? I can't pass it as a parameter because I need to get the latest version from inside the running thread. s_SCPositionData position; sc.GetTradePosition(position); // more logic here } Is this possible or is this a design limitation in Sierra Chart studies?

This is not safe: but I would like to get access to it from a thread that is running on a timed interval.
On the thread that calls the study function, you need to take a copy of the data, you want from SCStudyInterfaceRef sc and place it into your own allocated memory. And then, access that allocated memory, on the separate thread. And then there must be a critical section to protect that block of memory. We recommend using an operating system critical section. There is no safe way to do this other than explained. Otherwise Sierra Chart will become unstable. Sierra Chart Support - Engineering Level Your definitive source for support.
