First off, read, read, and read some more about the business of trading. Stocks and shares are one in the same I should mention, and I should also add that commodities are not equities. More importantly, after you have spent a few months reading up on Stock Trading, subscribe to a mock trading account for 6 months to a year and trade in this account(no real money) and track how well you have done. Then and only then, open up an account with about 10% of what you think you can afford to lose, and when that doesn’t work out as you had hoped, then you can chalk it up to a valiant attempt.

Thank you for the great advice been given… But daily i get calls from online share trading companies to invest through their company… Is it safe and will it help me earn money???

No harm in opening up an account with an online broker. Just make sure you once again educate yourself about your expectations and the types of markets you would like to invest in, make sure they guarantee a flat fee with no obligation of a minimum volume of trades on a weekly/monthly basis(seeing that this will be an investment account and not a trading account!), and start small(5%-10% of your total investment dollar to begin with). Keep posting here and I will continue answering as best I could if you have any more questions.

Firstl you should take deep knowledge about stock trading and share markets. Actually both are mostly same. And if you start your investment with online trading brokers then you should check their background details. you can start with small amount.
