A double bottom is a chart pattern with two bottoms very close in price. This pattern can be seen in all time-frames. There are a few requirements to classify a chart pattern as a double bottom:
Double bottoms have an enormous amount of "cause" or breakout potential as the price of the stock has moved back in forth within a defined range. So, when the stock finally breaks out, there is an expansion in volume and price movement. Breakouts can occur to both the upside and downside. If you enter a breakout of a double bottom pattern, you will want to keep a close stop above/below the support/resistance level.
When a stock breaks out of a double bottom formation, the price target is the range of the formation added to the breakout level.
