scalp

Making a killing on small price changes when share trading is called scalping. Scalpers, as these traders are called, will generally place hundreds of trades in one day, inundating the market with orders. Their goal is to trade a lot of shares at the asking price and sell them as fast as possible at a slightly lower or higher price for profit.

A talented forex scapler immediately exits their trading position if the market does not go their way. The scalper would make quite a number of trades a day from 10 to a couple of hundred trades - not holding on to losing positions or praying and hoping that their losing position will turn around.
