Why does the value returned from "MarketInfo( Symbol(), MODE_MARGINREQUIRED )" is '5' for EURSEK?

New comment
 

During EA testing, I find critical issue and later found the root cause is lotSize is high.

Then checked the value returned from "MarketInfo( Symbol(), MODE_MARGINREQUIRED )" is '5' for EURSEK.

I understand the margin/lot should be much higher than 5. How does the EA get 5? 

May I ask a favor for your suggestion to fix the issue? Thanks a lot. 

 
Friends, please help !
 
I think that this can only be answered by your broker
 
Thanks, GumRai. It's ok after re-install MT4.
