i hope u have tried your hand & gained some experience in some sort of trading (positional/intra) in cash/spot market, before trying to leverage your capital by trading in the futures/derivatives market.
Anyway, this forum is more for intermediate & advanced trading strategies & technical analysis.
If you want to brush up your basic knowledge (starting with ABC), then usually in every big brokerage house's web-site, you'll find "knowledge centres" where the basics about Futures,etc are explained.
I have one such link of sharekhan, which is presented in well manner:
