There is a time before MT5 move over to a new trading day, i.e., 00:00. There is a lull in quotes. During this time, someone run for stops. I had mine NZD stop placed a fair distance away and it was triggered. I have another broker and there was no run there, I did not have a NZD position there. So the few minutes before 00:00 and after is problematic. Agree that avoid auto strategies. I would say in all MT4/5 platform.
