However, `groups.py` does not seem to offer any way to get outcome variables from previous rounds (say equilibrium prices) cf. [the manual](http://otree.readthedocs.org/en/latest/object_model_and_self.html) (and skimming `groups.py`).  It would be nice to have a `group` version of `in_previous_rounds()`.\r\n\r\nI guess it can be access via `subsession.in_*_rounds()`,  but it seems less convenient.
