Rule-based trading is a mechanism that enables traders to overcome behavioural biases and emotional inclinations. It involves setting a written set of rules from start to end, which define which stocks to enter, when to enter, how much money to place, and when to exit. Once these rules are defined, the trader only has to wait for the target to be achieved or until the stop loss is hit. This approach is suitable for every type of trader, and the selection of rule-based strategies depends greatly on experience and temperament.
