No matter what happens, the dollar long-term is still bullish, it will only retrace. Bigger time-frames are important, Weekly and Monthly charts for long-term, Daily and 4H for medium term, when retracements happens, the market can't move one way up, the price must come down to move further up. I don't scalp, I'm a swing trader. I use 1H, 30M and 15M for entries.
