i have got myfxbook in the EA and smileys on the charts but MYFXBOOK is grey??
first check the expert advisor setting tab, perhaps you forgot 'allow dll import'https://www.myfxbook.com/help/connect-metatrader-ea
check those link for setting the ea.
when everything goes right, check expert advisor tab at the bottom your mt4 ( ' near journal tab' ), it will shown 'statement uploaded succesfully'
if problem still insist, means there's a problem with history data are no loaded, go to account history tab, right click, choose 'all history'
hope everything will goes well after that.
have a nice trade.
what can't be seen cannot be defeated.
