Disliked{quote} I don't know what to say, I don't have the issue and no other ideas why it is happening to you. There is no user setting for line thickness, I tested what you did, and it does nothing, charts still fine. With no other feedback, good or bad, as I said, I don't know where to start. Pretty sure that I already advised, re-install, restart, reboot, all the usual stuff. Let me have a wild guess however, it wouldn't be something other than Windows, would it? {image}Ignored
mt5 freezes until i have to force close the mt5 terminal least i now know no user setting so explains the freeze/crash....strange nothing happens on your side when you test what I did
