ravi!
trading or investing is not that easy as it looks,it is step by step unending learning process.so please don't depend fully on stock market as of now.
learn technical analysis and also how market react at different times....watch cnbc to know terminology and different issues as it comes and also expert views .
this forum has many good books,especially technical analysis books ,memebers has expressed views on books so choose few and read.
it is all about uptodate planning of how to react at different situations is most important aspect of this game.
only with time and experience you will gain confidence of how to what to issues.
so ...go with very small investments and study all market reactions.initially,step in to equities(cash market) only.
all the best
