I'm more of a scalper. I make big bids on currency fluctuating violently, quick in and quick out. I just do a very basic study of the candle stick charts and don't wait too long.
Well with all trading the bigger the risk the bigger the reward. At the end of the day its all a gamble. I know many if not all will disagree with that, and come up with statesments like if you keep up the flow and do you research correctly etc etc, but at best it just educated guesswork.
P.S : The dollar is hopeless !
