They all say the same thing. Random walk. Unpredictable. Random orders coming into the market. No one has any idea what is going to happen next.

As Brexit fears heated up again the past 2 weeks the price of GBP USD has been rising. Rising to the tune of 700+ pips. Straight up. One way. Parabolically. A move that defied gravity. A move that got underway before anyone had time to react. That is the Smart Money business model at work.
