WHAT IS A DOUBLE BOTTOM? The double bottom pattern entails two low points forming near a similar horizontal price level and signifies a potential bullish reversal signal. A measured strengthening in price will occur between the two low points showing some support at the price lows.
The double bottom chart pattern is found at the end of a downtrend and resembles the letter "W"(see chart below). Price falls to a new low and then rallies slightly higher before returning to the new low. Unable to push price to a new lower low to continue the downtrend, sellers give up and price bounces sharply from this area.The bullish confirmation is specified by a break in the key price level situated at the high point between the ‘bottoms’ resistance level (neckline).
