In the world of FX trading, an expert advisor is a program which traders install onto the MT4/5 platform in order to execute trades automatically, based on certain pre-set criteria.

Who is using EAs?

EAs are widely used in the FX trading community. Some traders exclusively use EAs, while others choose to do manual trading and deploy EAs on other trading accounts.

Why are traders using EAs?

  • Time - being a full-time trader requires a lot of time and patience. EAs allow you to carry out trades without manual intervention.
  • 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.

What are the disadvantages of EAs?

EAs follow rules, and cannot take into consideration things like change of market sentiment or a major news release that changes the direction of the trend. Furthermore, you should be familiar with the settings of the EA, understand the logic behind it and test it out on a demo before you deploy it on a live account - especially if the EA was not developed by you.

How are EAs built?
