Scalping is one type of trading trading system. It is a short trade for a few pips. When the news publishes that scalping time is very profitable. But I think for scalping we use a short time frame. That's not good for traders, because a short period cannot give us a good signal. Scalping is a technique for short time trading. This is a perfect trade for a small investor if he uses it properly. Small investors get more profits with scalping.
