But After creating this application I came to know that Zerodha also providing such kind of benefits which can fulfill my requirement in much better and faster way.
If you don't mind can we connect through Mobile or Skype, I will not take more than 5 minutes to clarify my doubts.
Your help will be highly appreciable.
