http://solutions.pages.soltest.onetick.com/iac/onetick-server/ep_guide/EP/Pseudo-fields.htm OneTick defines several pseudo-columns that can be treated as if they were columns of every tick. These columns can be accessed directly via __getitem__() method. But in case they are used in Expr they can be accessed via onetick.py.Source.meta_fields.
