Best thing currently is let zerodha release Pi. Let some people use it (who are zerodha fans). Lets wait for all early problems in Pi sorted out in a month or two.(I am sure there will be). Then take a call whether you want to use it or continue with other brokers. No point judging them now
I concur . This view seems to be most sensible.Don't deride them,let Pi come out finally ,judge it and continue if satisfied ,else look some where else.
