Thanks for the suggestion. The broker denied involvement. The lots are also correct. I check the lots again in the input window while attaching them to the MT4 charts.
I guess I will follow your advice and set everything up again. I was planning to upgrade my current VPS but I might as well get a new one and reconfigure everything from the beginning. The EAs are high frequency and contain several logical groups. With so many open trades at the same time, I believe a more powerful VPS may help with opening and closing trades in general.
