Hi Deepanshu,
What you need is further training in trading. There are many broking houses which provide you free training with some minimal stipend. There are other brokers who charge you some fees to teach but reimburse the same to you after you finish the course.
This i feel is a better route than starting at lower end of the ladder.
Once you have a sheet which is showing good returns you can jump the broking house and manage more money.
Hope this info helps.
Brokers are Arcadia, Religare , Dolat, Khandwala sec etc.....You can do your own homework
