a double bottom is not a difficult pattern to comprehend.... and it happens quite often
1. A stock in a long downtrend finally finds a bottom 2. From here a short lived rally ensues which then finds resistance 3. The stock is then sold down (usually on low volume) to the same level as the original bottom 4. A second rally on stronger volume pushes the stock past the previous resistance 5. Once this resistance is broken the second time there is a good probability of a sustained rally.
It's all there in the link.
