Scalping, on the other hand, is a form of trading. Roughly, it entails investing large sums in very short-lived positions and profiting by a few pips each time (beyond the spread). Expect to make at least 5 and up to several hundred trades a day, and to be watching minute-sized charts. Obviously, if your broker charges a large spread, scalping is not a good idea, since you must find an asset to invest in whose short-term volatility is represented by an amplitude that is wider than the spread.
