I have been using Groww platform for equities / stock trading for more than 2 years.
Some of the nice things are:
It is very simple and easy to understand. Supported by educational videos and self-help content in the portal and youtube - it becomes so much easier to get onboarded and start trading.
In addition to stocks - you can also trade in Mutual funds and ETFs. I have chosen to trade only in stocks.
You can also adopt your trading plan to be a Swing / Positional / Intra Day trader or be a long term investor.
Payment integration with Indian banks is robust and I never faced any challenges till date.
Their charges for settlements are very reasonable.
Get your reports, alerts and near real-time view of whats happening with your stocks or indices.
Somethings that I really wish that they include are:
Integration with 3rd party trading tools such as TradingView to make use of advanced charting, analytical tools that are available in Trading View. I happen to use other analytical tools(paid version) for my fundamental and technical analysis needs.
Crypto currencies trading is a big gap. I hope they introduce this as an integrated option or atleast through 3rd party integration with Cypto exchange service providers.
Groww platform has basic tools for technical analysis that are more than enough for a rookie but fails to impress the experienced ones.
