As the name implies, an expert advisor (EA) is a piece of software that makes trading decisions on your behalf. After installing Forex EA on a trading platform, the expert advisor or trading robot will manage your trades based on some predetermined criteria. These criteria are some form of programmed algorithms based on your specified trading strategies.

After you've identified your trading strategy, you can translate them into algorithms and develop a trading robot that will be executing trades on your behalf, instead of having to keep yourself glued to a computer screen.

An Expert Advisor (EA) is an automated trading program used on platforms like MetaTrader to execute trades without manual intervention. It follows predefined rules based on technical indicators, price action, or custom algorithms to identify trading opportunities. Once activated, an EA can analyse market conditions, open and close trades, set stop-loss and take-profit levels, and manage risk automatically.

Traders use Expert Advisors to eliminate emotional decision-making, save time, and maintain consistency in their strategies. EAs can operate continuously, even when the trader is offline, making them suitable for fast-moving markets like forex. However, their performance depends heavily on proper configuration, market conditions, and regular testing. Poorly designed or outdated EAs can lead to losses, making monitoring and optimisation essential.
