Different traders have different techniques for scalping, but one thing that can be universally agreed upon is that scalping involves tiny trades (both in amplitude and duration).
Typically, "scalping" is a specialized technique that involves making a tiny trade to capture a very small movement in the market. Whereas a "position trader" may engage in trades that are
intended to last for multiple days to months (aiming for targets of hundreds to thousands of pips), and a "day trader" typically engages in trades that are intended to last for less than a day
(aiming for targets ranging from 20 to 100 pips), a "scalper" engages in trades that might only last a few minutes aiming for targets of 5+ pips.
