another reason people lose is they trade small time frames.. If you opened the 1d TF and saw how easy it is to see trends you would be amazed.
the only issue is that you cant be trading huge lot sizes as when you scalp the smaller time frames.
I typically trade 0.01 per 1,000 in my account per trade. ( sometimes per 2,000 just to be safe)
focus on booking pips rather than dollars and you will become a much better trader
