Scalping is an important aspect of forex trading. General belief is that scalping is one of the safest ways of trading. You enter the market, initialize a lot of trades and walk away once the prices rise a little and you get a reasonable profit. But scalping also involves very high risk because of leverage.
As safe as it sounds, scalping may result in a complete disaster, if you take just a single step in the wrong direction. Also, even if you earn in most of the trades, you are bound to lose in a few trades, which neutralizes your profits from those successful trades
