A specific term in forex (especially MetaTrader) for an automated trading robot. EAs are pieces of code uploaded to a trading platform (like MetaTrader 4/5) that automatically monitor price data and execute trades according to programmed logic. Each EA implements a unique trading strategy (often based on indicators or signals) without human intervention. The EA framework is widely used by forex traders to create, test, and deploy automated strategies, including those leveraging AI techniques internally.
