Hi
@Thread Starter,
If you simply want or can trade in Nest Trader or Nse Now and want the lowest brokerage in the market with best service, Go for SASONLINE. And if you wish to have trading plate-farms like Nest Trader, PI or kite go for ZERODHA. KITE and PI are the best trading platefarms i have ever used. If you trade on cash segment with delivery Zerodha don't charge any brokerage.
There are several things I like about both of these brokers.
1. KITE's charts are superb believe me i forgot even Amibroker which is the best charting software in the market.
Go and explore yourself hope you will like both the brokers.
