Double Top and double Bottom

No chart pattern is more common in trading than the double bottom or double top. In fact this pattern appears so often that it alone may serve as proof positive that price action is not as wildly random as many academics claim. Price charts simply express trader sentiment and double tops and double bottoms represent a re-testing of temporary extremes. If prices were truly random, why do they pause so frequently at just those points? To traders the answer is that many participants are making their stand at those clearly demarcated levels.

If these levels undergo and repel attacks, they instill even more confidence in the traders who've defended the barrier and, as such, are likely to generate strong profitable countermoves. Here we look at the difficult task of spotting the important double bottom and double tops, and we demonstrate how Bollinger Bands can help you set appropriate stops when you're trading these patterns.
