I've been using Rksv upstox account from past one year. This is the best of it's kind. If you are a fresher to trading this is the one I would suggest. Rksv is the only Indian broker that has zero charges for new demat and trading account opening, zero annual maintenance charges, zero brokerage charges on delivery and Max 20rs on intraday trading. It comes with a beautiful upstox pro app on Android play store. Users can download and do trading easily on this. Rksv also follows paper less new account opening. Try this.
