The Strategy Builder doesn’t work. It doesn’t run. How do I run it?

Molanis products are written in Java so you need the latest Java version installed in your pc. You can get it at Please install java to solve the problem.

The Strategy Builder doesn’t work. It opens another software (Winzip, software to compress/uncompress file/ Nokia software/). How do I fix it and run it?

Windows uses file associations to make a link between programs. For example pictures are opened with paint, docs with MS Word, Jar files with Java. Jar is also a way to compress files so sometimes Jar is associated with a software to compress files. Molanis software is a jar file. It should be executed with Java. The easiest solution to this issue is to reinstall Java and the file association will be changed automatically. Another option is to change the file association manually.

An alternate solution is to edit the properties of the icon - link to Molanis on your desktop to :

C:\WINDOWS\system32\java.exe -jar C:\Molanis\Strategy_Builder\molanisSB3xx.jar

(xx is your installed version)

Where is the Molanis Executable .exe?

Molanis Strategy Builder is written in Java so its executable is a .jar file. Executables Java programs have a .jar extension. Not all executables are .exe You can execute Molanis from the icon on your desktop, from the Windows Task Bar under Molanis, or going directly to the Molanis installation directory.

Using MetaTrader 5 in new Windows versions

Windows Vista and Windows 7 users: If you want to avoid headaches, do not install MT5 under the Program Files directory. Why?

New versions of windows have a security feature to protect the directory Program Files and its subdirectories. With this features files are also saved under C:\Users\YourUserName\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL5. This causes problem, since MT5 look for the files to display in the Navigator

under C:\Users\YourUserName\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL5 and not under C:\Program Files\MetaTrader 5\MQL5

So if you see your file in C:\Program Files\MetaTrader 5\MQL5\Experts or in C:\Program Files\MetaTrader 5\MQL5\Indicators but you do not see it in the MT5 Navigator (the place where you drag and drop it in the chart) probably the syncronization between C:\Program Files\MetaTrader 5\MQL5 and C:\Users\YourUserName\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL5 is not working. The fix is to copy the files manually from C:\Program Files\MetaTrader 5\MQL5 to C:\Users\YourUserName\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL5 (take into account that YourUserName is your windows user and D0E8209F77C8CF37AD8BF550E51FF075 may be different.)

EA Generation

How do I solve the "The Expert Advisor couldn't be created" issue? (This only applies to old MT4 versions. Starting on MT4 build 600 this is not a problem anymore)

Seldom users have issues when creating the EA. The Builder gives them a message advising to verify the MT4 configuration. They click in the Verify button and the configuration is not wrong. This happens in Windows Vista and 7 most of the time.

The problem is not the Strategy Builder. It’s not Java. The problem is that Windows security settings are not the same among all MT4 installations. People that get the standard MT4 (provided by Metaquotes) do not have any issues. The issues are faced by people that get MT4 from certain brokers who do not give writing rights to the MT4 directory to the normal windows users (Your user – not admin users). In plain English, when the Strategy Builder tries to create the EA in the experts directory it fails because the normal windows users (your user) does not have the right to create files in the experts directory.

To solve the problem you can either run the Strategy Builder as a Windows admin user or become an admin user (which is difficult for some users). Some users had some success reinstalling MT4 in any directory but avoiding C:\Program Files. The best solution is to change the windows permission on the MT4 directory. The following graph shows the right permissions on the left and the wrong ones on the right.

Using MT4 Build 600 or higher

In build 600 MT4 had some drastic changes. The directory structure and file names changed to be like MT5 - this is part of MetaQuotes strategy to join MT4 and MT5 in a new product. If you use MT4 build 600 or higher please install version 3.2

If you use MT4 Build 600 or newer, in the Strategy Builder you need to setup:

1. the MT4 directory (the directory where the MT4 Editor MetaEditor.exe is located i.e. C:\Program Files\MetaTrader 4).

2. the MQL4 Folder:

To find your MQL4 Folder open MetaTrader and go to menu File - Open Data Folder. Then click on MQL4.

Here there are two options:

-If you use MT4 Build 600 or newer on Windows XP, Professional or older Windows versions, your MT4 MQL4 Folder should be something like C:\Program Files\MetaTrader 4\MQL4 - that directory is where the Experts and Indicators directories are located. EAs will be saved on C:\Program Files\MetaTrader 4\MQL4\Experts, Indicators will be saved on C:\Program Files\MetaTrader 4\MQL4\Indicators

-If you use MT4 Build 600 or newer on Windows Vista or newer Windows versions (i.e Windows 7 and 8), your MT4 MQL4 Folder should be something like C:\Users\YourWindowsUser\AppData\Roaming\MetaQuotes\Terminal\YourTerminalID\MQL4. Expert Advisors will be located on C:\Users\YourWindowsUser\AppData\Roaming\MetaQuotes\Terminal\YourTerminalID\MQL4\Experts and indicators will be located on C:\Users\YourWindowsUser\AppData\Roaming\MetaQuotes\Terminal\YourTerminalID\MQL4\Indicators.

How to find the MQL4 Folder?

To find your MQL4 Folder open MetaTrader and go to menu File - Open Data Folder. Then click on MQL4. The MQL4 Folder contains the Experts and Indicators directories.
