- Have you compiled it, then it is maybe in the Expert folder. That happens sometimes.
- Have you more MT4/5 terminals be sure it is in the indi folder with the MT4/5 you have open.
If there would be an error in the code, you see the ex4 and when you try to load it, your terminal will most likely freeze. Then you have to delete/rename this indi and restart the terminal.
1,144 ex4 files
Try copying your mt to other folder, clean up the indicators folder and copy just the ones that you use to that new instance
