How Do Forex Advisors Work?

Forex Trading involves a lot of skill, dedication and experience for traders to be successful. Professional traders with years of experience behind them, can manually scour the market for winning trading opportunities, taking the right decisions in order to turn in a profit. However, this level of skill and experience is not possessed by most novice traders who come to the market.

Before attempting to explain how an Expert Advisor works, we should first describe the types available. Depending on the nature of Expert Advisors, there are 4 main types.

  • Breakout Expert Advisor: This type of EA opens a trade when a price breaks through the support and resistance levels which are preliminarily determined.
  • Scalper: Expert Advisors falling under this category have the goal of securing small profits once available. It opens and closes several trades for profit, with some EAs capable of trading upto 400 to 5000 times a day, depending on how market conditions are.
  • Hedge Expert Advisor: EAs under this category deal with two opposing positions. They diminish the loss on one hand, while facilitating the profit on another.
  • News Expert Advisor: This EA takes advantage of various news events as well as big price moves that take place during major news releases from around the world.

How do Expert Advisors Work?

Expert Advisors work following the two basic steps, as mentioned below.

  • They first analyse the current market, using built-in technical indicators. They then provide signals to open positions, after completing the analyses.
  • Expert Advisors then open orders, following a set algorithm. This is done when signals are received from at least two indicators. Expert Advisors close orders when a trend reversal signal is received, or when stop-loss and take-profit signals are triggered.

When using an Expert Advisor which is MetaTrader compatible, the EA must first be attached to a chart on the platform.  When running on MetaTrader 4 or 5, an EA can consider the myriad of factors and elements to decide what move to make next. Because this method provides a wide range of price affecting elements, as well as the discipline of emotionless trading, using EAs have become a popular method for novice traders to earn considerable amounts of money.
