A trend causes the FDI to move down, and we can expect the trend to end when the FDI reaches the 1.35 level. The FDI does not tell us if the trend will reverse sharply, or if prices will begin to range. It only tells us that prices should go back to acting like a soon.
As the market ranges, the FDI will move up. When the FDI reaches the 1.50 level, we can expect a new trend to begin. The FDI does not tell us which way prices will break, only that a break should be coming soon.
