It is very difficult to me...I always trade in the opposite direction and lost money...
It's sad, but you're not the only one who loses his money trading. According to statistics, 90% of traders lose their money. And the fact that almost everyone writes on the forum that they trade and make a profit is just a desire to pose as a successful trader, and not a statement of reality.
Some traders prefer to be okay and continue trading hoping for some luck like they are in gambling rather than telling what really happens to them.
That certainly happened to me, not all the time I was in profit, the same thing with losses but that is normal. But as I've tried to evaluate the number of times that I was in profit, I find out that I lost more than what I earned - quite disappointing. So I decided not to focus on trading and I'm now more into investing because I see it was less stressful.
