@Gaurav 5paisa support system is not that perfect and there are heavy hidden charges. They charge their clients Rs. 10 per trade.
The term “tough competitor” referred to as when broker is offering better than Zerodha, not based on no. of clients.
I mentioned Finvasia because they are offering zero brokerage brokers on all segments and great services. While Zerodha is only offering zero on delivery equity and lack of support.
I mentioned Upstox because they have a great platform to trade as compared to Zerodha. But, it’s irritating that Upstox is facing some issues too. I hope they fix it and won't happen again.
