Yes the beginners has to be careful to invest the money in the business. Forex trading is very good business for the every one. Forex trading can give the huge earnings to the trader. Forex trading is the risky business so the person has to be very smart for this trade. A little mistake may cause the big loss. I think for a new trader he/she must have to think about the leverage now a days 1:1000 leverage is the highest in Instaforex. I think leverage can give us a opportunities but beside this it can make our account in danger mood. so for a new trader I think 1:100 is the best leverage ratio. A new trader must follow the money management criteria strictly.
