Installing indicators and expert advisors in Metatrader 4

By default, several dozen indicators are installed in the MetaTrader, and it is quite possible to trade only with them. But why limit yourself if you can find hundreds of custom indicators in the public domain and install them in the trading terminal without any problems.

In the simplest case, you need to place the expert Advisor file in the experts folder. Some expert advisors also require the installation of library files, additional scripts to work with, and the General procedure remains the same.

We will analyze the robot installation using the example of the Vector expert Advisor. in addition to the adviser files, you will need to copy the library and settings files to the appropriate folders.

In this case, you see 2 expert Advisor files, one with the extension .EX4, and the second is mql4. If you copy both files to the experts folder, you can then edit the robot code. If only the file with the extension .EX4, the expert Advisor will work, but its editing will not be available.

The EA is installed in the following order:

launch MT4, in the file menu, select " Open data directory»;

Select the "Open data directory" item in the window, select the MQL4 folder, open it;
Go to the MQL4 folder
copy both files of the expert Advisor to the experts folder. You can also copy the include, Libraries, and Presets folders that were included with the expert Advisor. When you have a question about merging, just agree with it;
after that, you need to restart the terminal and check whether the expert Advisor that you installed has appeared in the list of user settings. Go to the Navigator and find our expert Advisor in the "Custom" section.;
The expert Advisor is visible in the Navigator, so it is installed correctly. we try to add it to the chart, a window opens with the settings, so everything works;

As for the installation of indicators, it is performed in exactly the same sequence as the installation of the expert Advisor. The only difference is that you need to copy files to the Indicators folder (located in the MQL4 folder).

The expert Advisor is added to the chart in a similar way: drag it from the Navigator window to the chart of the desired currency pair, set the settings, and it will start trading.
The fact that the EA is working can be judged by the smiley face in the upper right part of the screen. if the smiley face is sad, then auto trading is not going on. In this case, in the Tools – Settings – expert Advisors section, set the parameters as shown in the screenshot.
