One of our clients would like to understand file size of TickHistory data to determine data capacity in their database.
They would like to know the size of data in Python pickle files through REST API.
Is it possible to guess Python pickle file size from csv file size in TickHistory GUI?
For example, some files are 7.4GB and 29.7GB respectively in csv format from TickHistory GUI (after unzipped from gunzip format).
In that case, roughly how much data capacity is expected in Python pickle format?
