My GF is an analyst and she was showing me all of the ways the new API is going to piss off her firm’s clients with all of the changes. I won’t pretend to understand it. Excessive rounding making it difficult to get the resolution some clients expect? Something about midnight causing duplicate counts… there was a lot. Mainly it seemed like issue would be the major corpos being mad at the firm because the reporting can’t be exactly the same as it was before.
