Professional day traders that make money in the stock market with high frequency and lower profit are called scalpers. The goal is to take advantage of small inconsistencies in the market in addition to quick movements (changes in value in a matter of seconds or minutes).
A scalper may only be in a position for five or 10 seconds or possibly a minute. A scalper also tends to place a higher frequency of trades and as their profit is normally lower per trade. A higher frequency of positions (entering and exiting trades) is needed in order to make higher profits.
