Hi Balu,
Welcome aboard.
Firstly, and I'm sure the seniors will agree, there is no such thing as an expert.
Please be willing to learn and continue to learn as the markets are a dynamic and constantly changing environment.
Search for the beginners guide on this site, many of the senior contributors have been good enough to put their experience in documents for you to get started.
Paper trade and test the strategies with no risk to your capital until you have experience of what works for you.
I wish you patience and profitability.
Class.
