Zerodha is worst no support from broker. Each and every thing U loss the money and gain the Knowledge. No customer Support you have raise the Ticket. Ticket is total waste concept. for analysis you can use another websites also. for trading only every one support. Sharekhan is Leader in that to train and demo to educate the new traders. but investing is your own risk. Sharekhan is always best compare to zerodha..... Everyone support zerodha because of the link referal offer they get cash back and make you fool.
