Whatever, that you feel you are comfortable to use then use it. For me, I use both them. Actually, in mini and cent account I use pip value since the value in dollar is not really that high. On the other hand, I’m also trading with standard account as $ target. Since in little amount a little pips chance is already worth dollars in term of profit and loss. So, for me it’s does not matter if you use pips or dollars.
What matter is that you are comfortable using it. Because, just imagine in cent account I earn only 0.50 $ after making 50 pips. Besides, I get 10$ in my standard account when I manage only 10pips. That’s it.
