After building the trading system/strategy for couple of weeks now, I just got to know that Zerodha doesn't allow intraday trading on ~750 companies, out of which ~470 companies are Group A, B companies (top 2 groups of BSE/NSE which denotes better quality companies and where all other brokers allow intraday trading). While, as per BSE/NSE regulations, only XT, T segment companies are barred from intraday (T2T segment), zerodha has put a blanket ban on around ~600 A, B, XC, XD companies.
This is seriously disappointing and a waste of efforts on my side. I would have understood from the internal risk management perspective which could have resulted in a high margin requirement but a blanket ban just doesn't reflect well on zerodha's technical and risk management capabilities.
Leaving alone the automated trading, I believe this is critical for normal trading first.
Please do clarify and propose a feasible solution on this as I have spent a considerable time on this without knowing these critical aspects beforehand (and I suspect many others would realize sooner or later).
