Hi, without more context it’s difficult to say what happened. I suppose the account is closed and we can’t look into it in detail to understand the issue.
You might have global variables (under Tools > Global Variables) that affected the protections or if you were disconnected from the Internet (if trading on a local PC, or for some reason your VPS was disconnected) this would also prevent the EAs from working.
Without looking into the account, I can only guess.
