I experience we are much satisfied with demo results and in very little time feel now trading is no more difficult . We can now handle it easily . But reality is different . Live trading results are not much satisfactory as we start it . I feel after real trading experience that demo trading for a long time should be with us.If we are satisfied with the result in demo account then we can head to real account and we should be careful while trading because Forex market is highly risky so we should do trade with money management skills.
