I found my problem for running EA trading
my EA not running for 12 hour
my mt4 close (may be mt4 have error and close or may be I missing close when I close remote desktop by click button X top right conner)

I found my EA stop working because I open to see update at myfxbook and found Updated: 12 hour ago

may be good for create myfxbook EA for alert service if EA not send update or send update to tell I am live (EA) with in 1 hour system may be send email to alert me via email to know about it for SMS user can option to send email to sms email of user provider
just idea

on case my VPS reboot or server reboot I can solve problem by create vps to auto login and setup mt4 to rung from startup
but on case mt4 hank error and close my server my vps still runing not reboot

Thank you for reading my suggestion
sorry for my English too.
