I would discourage newbies from using any leverage in their trading.
As you are a newbie, you'd better pay more attention to the quality but not quantity. It is the same thing as learning how to drive on high speed without knowing the fundamentals of driving This will lead to the catastrophy. Trading is quite the same thing. Leverage is made in order to make more money using small budgets to trade. Leverage is a kind of a loan which take from the broker you are working with. If your trade is successful, then you reap higher rewards, however, in case of failure, your losses will be much higher than they could be without leverage. So, I believe that it is an open secret that in the beginning of your trading you'll face with many losses and your objective should be not to make them too dramatic for you to turn away from trading.
