Scalping
Scalping is a form of action, which is designed to make many, mostly small, short-term gains to be realized by the holding positions. A scalper holds its positions usually only a few minutes, sometimes seconds, in order to close with a gain of only a few pips.
To scalp profitably is necessary in, generally, a high capital and high leverage, open trades at a volume that even with just a few pips profit is a reasonable equivalent.
