Hi!
Sometimes I have had to load an indicator with a bug in a loop, and MT4 would freeze and shut down.
The solution for me is to delete the indicator from the indicators folder, and start MT4.
Since it cannot be loaded into the chart, it no longer freezes
Re: Fix: MT4 keeps closing or crashing after loading
