I have never been sad when I lost in trading. even when I get a margin call. I will remain calm. that's all because I understand that in every trade there are advantages and disadvantages. make a loss as our learning material to get a better profit. and Forex trading requires the full concentration of the trader if one of the traders is well-versed with a good strategy so he must pay attention to his trade because he knows that in the future what he has invested in the past now is the time he got at that time concentrate on trade.
