It is a very stressful business, perhaps the one who think about that it's not is the person who haven't started to trade in Forex trading because for sure they haven't experience to lose any amount in Forex trading because when you lose money in here, especially when you lose money first time in trading then it may take time for you to move on for the losses. Especially when you trade without proper knowledge you might just end up regretting your action. And can be hard to move on, and that can be stressful.
Yes Forex is a very stressful business. One should always take breaks and intervals from trading to refresh his mind . Mental stability is essential to take good and profitable decisions in Forex. a sad mind is a losing mind and therefore a person should avoid Forex when he is mentally unstable or upset.
