I apologize in advance for asking something sure to have been answered a few dozen times now. Unfortunately, I’ve been searching, but I can’t find my answer.
How do I install custom indicators into MT4? I’ve tried figuring it out, but I’m getting no where.
I’m trying to install .ex4 and .mq4 files.
Any help would be greatly appreciated.
Put the .ex4 file in
C://ProgramFiles/YourMT4Program/Experts/Indicators
Close MT4 and re-open.
A shortcut that I found with .mq4 files is to open them in the Meta Editor, and then compile them. It will refresh the indicator list with the new indicator/EA in it so you don’t have to close MT4 and re-open it.
Thanks for the help guys!
I’ve successfully got them in the custom indicator file, but nothing shows up when I try to open them on a chart.
Does each indicator need a mq4 and et4 file?
Are these files related together as in a system?.. or unrelated indicators?
It’s a system, but not a system written as a whole for MT4.
Basically, it’s a system predicated on several custom indicators that I found on a different site. I’d post the link, but IDK if that’s permissible here.
It’s something I wanted to demo for a while, but can’t get the indicators to actually show up.
Unfortunately, I’m still having trouble with the custom indicators.
I moved the mq4 files from my desktop to the experts/indicators folder. I’ve closed and reopened MT, but still can’t find the c.i.'s.
Is there something stupid I’m missing?
Hate to bump my own post, but I still need some help understanding what I’m doing wrong. Any help would be greatly appreciated.
Make sure it was the .ex4 file that was moved. I believe the mq4’s are just source code (I could be wrong).
When you say moved, how did you move them? If you see a file on your desktop with the yellow diamond icon and .mq4 extension, right click and chose save as and save to your experts>>indicators folder. Close and reopen MT4. If you see it in the indicators list under custom indicators … you should be able to add it to a chart. If not … maybe the problem is with your MT4 program. Either uninstall & reiinstall it, or try another MT4 demo from a different broker.
Thanks for the help guys, but still no dice. I removed the files, and tried it again. I was hoping there would be an option somewhere that I needed to check, or something like that. Oh well.
Yes, MT4 can be frustrating just like all the other ones out there.
You can only see so many indicators on the dropdown list.
Try this.
Use the Navigator window and drag the custom indicator from there and drop it onto your chart.
If you don’t see the Navigator window, hit the <F11> key. You should see it on the bottom left or click VIEW and then click on NAVIGATOR.
Hope that helps.
Thanks RumpledOne. My problem is getting the c.i.'s to even show up in the Navigator window. They’re in the experts/indicators folder, but don’t show up while in the platform.
sign off MT4
delete the MQLCACHE.DAT file.
sign on MT4
It will take longer to load as MT4 compiles all the indicators.
Ah, I didn’t understand that they were not even showing up in your Navigator list.
If the fix below does not do it, I would uninstall your MT4 and reinstall, add the indicators and make sure their icons are identical to other icons in your indicators folder. If you have a ton of indicators in there, maybe eliminate some you will probably not use (you can always get them & add them back again if needed)
If that doesn’t work, try a new broker for a demo MT4, the problem may be in some sort of corrupted file from this broker in this version.
I was using a demo from Interbank and one day it just would not let me edit the indicators any longer … the only fix was uninstalling & reinstalling.
Finally up and running!
Thank you guys very much for your help 
Great … what fiinally worked??
the mqlcache.dat file did the trick.
Cool, I’ll have to remember that one.
