Another bad thing I noticed about 2 day charts is some of the bars are actually 1 day. The bar from Friday sometimes is blended with an inexistent Saturday bar, and an inexistent Sunday bar is blended with the Monday bar. I won't be using them any more. Not so sure about MT5, if enough traders will start to use MT5 instead of MT4 I think they can become good time frames to trade even if now they aren't.
