MC is not just controlling psychology but also implementing good risk management. But the role of psychology here really cannot be underestimated.
The best way to avoid margin call is
1.reduce your leverage or make it smaller such as 1:100
2.use the smallest lot it means order just use 0.01
3.do not make more than 2 orders per day
4.always make stop lose and risk your capital 5-10%
I think with do that all of us will be far way from margin call.thank you
