Maybe someone faced a problem. There is an expert Advisor running MT5 on a third-party VPS. Ping to the server is an average of 3 MS.
When the EA is first installed, it works like a clock, the speed of order execution is 3-4 MS.
Over time, the execution speed increases by up to 1000-1500 MS. It is treated only by overloading the terminal.
Where’s the sore? VPS? The terminal?
Maybe you need to clean some cache?
