|Failed Double bottom|
A downward price trend bottoms out, rises, and then bottoms again before climbing. Prices trend down and should not drift below the left bottom. There should be a 1% -2% rise or more between the two bottoms, measured from low to high. Bottoms should be at least a few intervals apart. The second bottom price is less than the first bottom price. The confirmation point is the highest high between two bottoms. This pattern shows that either confirmed double bottoms or possible double bottoms have failed.
