So why are you giving the impression that you are failing badly? From what I see here that is not the case. I like what I see. My concern though is that you are dabbling in too many instruments and using a variety of lot sizes. I would suggest one lot size, one pair, one profit target. And I think fifty cents is too much pressure for what you are doing. I have been there. If you work with twenty cents you are more likely to be in the game much much longer. When your account is bigger you can increase your profit goal.
There is a youtube video by Ross Cameron called Scalp Trading: A Beginners Day Trading Strategy. When you watch it put the word pairs where he has stocks and it should help you some.
And take careful note of what he said at 25:16. Others will disagree but that is my two cents.
