  • Emotions - EAs clearly follow the instructions, and for traders who struggle with managing their emotions, it might be easier to trade that way.
  • Diversification - some traders who trade manually might decide to use EAs to diversify their strategy. For example, a long-term trader trading exclusively indices may look into short-term EA strategies that trade currencies.
