Drilling further into the term of scalping, it implies a close shave. Any barber worth his razor shears hair off a head or face by running his cutting implement as close as possible to the surface. Great care is taken to not nick the skin as drawing blood is a sure thing to dissuade returning customers. Forex scalping probably works on the same basis of cutting real close, taking quick and short movements to achieve its objective. Those in this business do not plan to stick around for desserts as their focus is on swift and small returns carried out over and over again.
