The formal MT4 we were used to was called MT$ build 509. As most of you know, metaquotes has update Metarader 4 to build 600. Build 600 brings about massive changes from the previous stable version of build 509. For example, trade execution time has been reduced because MT4 terminal does not have to establish a second connection with the broker’s MT4 server in order to send trade orders.
With such improvements there has to be changes within the internal directories of MT4.
Your indicators will no longer install the way you used to
This guide will show you exactly how to install them in the new build 600++
3 steps to install your custom indicators into MT4 build 600
Step 1 – Go to file –> Open Data Folder (note you must follow this step, this is not the same as going to C:\program files\MT4 terminal. You will see in step 2 that the directory is stored in C:\users\your name\appdata\roaming\Metaquotes\Terminal…)
Step 2 – Double click on MQL4 –> double click on Indicators
Step 3 – Paste the .ex4 file into the indicators folder (don’t paste other file types such as .mq4 – MT4 build 600 cannot read the old MQL4 language. If you only have .mql file, download the .mq4 to .ex4 compiler here
That’s it! Restart your MT4 terminal and you will see your custom indicator appear!
