MetaTrader Tips – Expert Advisor Installation
MetaTrader Expert Advisors file should have the file extension of .ex4 (compiled code) or .mq4 (sourse code). First it is necessary to copy this file to the folder Experts of the MetaTrader working directory (usually C:\Program Files\MetaTrader Broker Name or MetaTrader).

The second step is to restart MetaTrader. After the restart the expert should be added to the list of experts in the Navigator window. It necessary to stress that the colored icon corresponds to mq4 file. If you have an ex4 file only, an icon in the window Navigator will be grey. The same grey color may mean that the errors in a source code appeared.


In order to check errors in the EA, you can press F4, the editor of language MQL4 , and then it is necessary to load the source code of expert into the editor. Press F5 in order to compile the expert advisor. In case of success, the sentence ’0 errors’ will appear in conclusion window. Warnings are not errors and their presence does not hinder the successful compiling.

The off-exchange retail foreign currency (or forex) trading uses currency markets from a variety of countries to create a trading market where large volumes are traded and exchanged daily. We believe if you aim to profit from Forex trading, then you would need to own every single pip that you can get. But this is easier said than done, specially if you are new to the Forex market. It occurs because traders-beginners, keen by passion, rush to trade without having a Forex trading strategy. Even if they have a Forex trading strategy there is still a human factor. That is why it is necessary to use MetaTrader Expert Advisors.
