Both manual forex trading strategies and automated forex trading strategies can be used to create trading signals in the forex market. A manual system involves a trader sitting in front of a computer screen, searching for trading signals, and determining whether to buy or sell based on the signals. Trades are executed automatically by automated systems, which are developed by traders and consist of an algorithm that discovers trading signals and executes them independently. These technologies are designed to remove human emotion from the equation, which may boost performance.
