The types of EA in MT4

Experienced Forex traders who have developed their own manual trading FX systems often hire MQL4 programmers to automate their systems, therefore creating a custom MT4 EA.

How does an EA function?

This program operates by calculating the various indicators which it was developed to use, and takes action when market conditions meet the right criteria as described in the Expert Advisors' source code. For instance, an ordinary MetaTrader Expert Advisor may have a setup something like this: 'If the 20 day and 9 day MA cross with the 9 day Moving Average above the 20 Moving Average; and the RSI is higher than 50 then you should open a long position (i.e buy)'. This example shows us that you can assign an infinite amount of conditions for entering and exiting the market and managing certain trades for trailing stops as well as multiple take-profit levels.

Generally, an MT4 Expert Advisor is divided into three parts: a startup or 'init' function, the major function, and a 'deinit' or cleanup function. The EA will run through its startup option and upon startup and it will also run through its cleanup function at the end. At the same time, the MetaTrader 4 EA program runs through a cycle of its key functions over and over with each incoming tick whilst it is attached to a chart. Expert Advisors, and particularly a free MT4 Expert Advisor, will not start another cycle for a new tick in case it is still in the middle of the foregoing one.

This is quite a simple summary of what a simple Expert Advisor can be designed to do. You can ask it to check your account, in case there is enough equity to start a trade, and then you can ask if there are any available trades to join at the that moment. If there are some, you can ask whether they tend to be closed or whether they require their trailing stop to be adjusted. In the case where there are no open trades at all, you can ask if the market conditions are right to open one.

The types of EA for MT4 in detail

There are different kinds of Expert Advisors MT4 available for the MetaTrader 4 trading platform. We will discuss some of the most popular and common types. This isn't a comprehensive list - there is no doubt that there are other types of Expert Advisors.

  1. News MetaTrader 4 Expert Advisor - this a hedging EA. The News Expert Advisor is developed to take advantage of news events and the significant price shifts that can take place during financial news releases.
  2. The Breakout Expert Advisor - this is programmed to open a trade the moment the price breaks through predetermined support and resistance levels.
  3. Hedge Expert Advisor - every EA that plays two separate and opposing positions and reduces the loss on one whilst making maximum profit on the good trade falls under this category.
  4. Scalper Expert Advisor - a type of Expert Advisor for MT4 that will get your account cancelled, or at least heavily limited by brokers. Its purpose is to secure small profits just as soon as they are available.

Is it possible to run more than one EA at once?

The answer is yes. You can use multiple instances of an EA on the MetaTrader 4 client terminal. It is worth noting however that not all Expert Advisors work together on one terminal. This mainly due to the fact that they will try to handle each other's open trades. Programmers get around this by applying special numbers in the market entrance part of the Expert Advisor's source code.

There are some platform restrictions. One Expert Advisor MetaTrader 4 can only communicate with one trading server at any one time. If multiple Expert Advisors show a lot of activity on the same terminal and more than one tries to communicate with the trading server, you will eventually receive 'trade context busy' errors in the logs. This occurs if you have too many EAs on a single client terminal.

Do MT4 Expert Advisors work?

We suggest discussing the issue of whether EAs for MT4 and free Expert Advisors for MT4 in particular really work. As it is representative of automated trading software, EAs cause quite a lot of debate on the internet. First of all, let us define the positive things:

  • An EA does not sleep - it can work 24/7
  • It is deprived of any emotion
  • Nothing can distract an Expert Advisor from working
  • Expert Advisors are available for the MT4 platform

Beside standard disadvantages, which includes the lack of creativity, there is something more. It is really hard to verify the accuracy of any EA unless you have used it yourself. Let's outline two scenarios that could occur as a result of EA use:

  1. The first one is that the Expert Advisor for MetaTrader 4 tweaks countless times and it still cannot show steady profits on a demo.
  2. The second one is that the EA actually does really well on demos, but for some unknown reason when traders try to apply them on live accounts with their own funds, suddenly the EA does not work as well and unfortunately traders are losing money.

It is vital to understand that there is no holy grail in Forex - before relying on anything else you have to rely on your own skill and knowledge.
