It’s my first and only app for trading till now.
Started trading last year with this app. And It is been a rollercoaster for me. But app never disappointed me.
For starters they offer you tutorial. There executives tells you process to join and trade.
No one time charges but there is many charges which comes with trading and I read they are nearly same on all other platforms.
If you are new to trading then I suggest you to join this. And if you have knowledge then compare others with your requirement as charges are different with all different platforms.
