The question has been answered already by many people and that should be more than enough for OP, however I would like to point out another fact about this question. It is hidden and not talked openly but the reality is that if you do not know the answer of this question and yet still opened a long position, you have to realize that it is not really a good idea to start. At the end of the day, leverage trading is such a risky business that you should be avoiding being part of it if you can't really do something about it.

If you are really doing all you can, and you are still losing then it is fine but if you do not know the answer to this question and still trade, you may end up with a big loss in the end.
