When I lose a trade I feel bad. Sometimes I feel like giving up which I believe is normal as a human. But I know that the fault is from my side and I accept it. I try not to make the same mistake in the next trade.
I believe MT4 should be preferred by newcomers as MT5 has lots of extra features that makes it a bit confusing to use. But at the end it is the trader’s call which he is comfortable using.
