Scalping
A trading strategy that attempts to make many profits on small price changes. Traders who implement this strategy will place anywhere from 10 to several hundred trades in a single day in the belief that small moves in prices are easier to catch than large ones.
Scalping is the act of cutting or tearing a part of the human scalp, with hair attached, from the head, and generally occurred in warfare with the scalp being a trophy. Scalp-taking is considered part of the broader cultural practice of the taking and display of human body parts as trophies, and may have developed as an alternative to the taking of human heads, for scalps were easier to take, transport, and preserve for subsequent display. Scalping independently developed in various cultures in both the Old and New Worlds.
