Hi @dogville86 - there are different ways to approach this depending on exactly what you are doing with the data but I'd likely import the file using Ami's File Input/Output functions that can be found here and place the contents (or what is needed) into a static variable.
The static variable can then be accessed by any of the charts/formulas as you wish.
i am headed towards using AB to generate feature data for submission to python to train and use ml models.
i believe part of that process involves figuring out how to use AddToComposite() to generate database tickers. What u r asking seems like the same thing.
i believe i am 3 weeks away from making this happen. If u r wiling to wait i will try to do something we can both easily use and share it with u.
