====== Al Brooks: Double bottom bull flags and Double top bear flags ======

Al Brooks describes two patterns that I use very often in my strategy for trading. **Double bottom bull flag** is pause or flag during the development of the bull trend, in which there are two spikes down to almost the same level, and then the bull trend resumes.

**Double top bear flag** is a pause or flag during the development of a bear trend, in which there are two spikes up to almost the same level, and then the bear trend resumes.

These two patterns are actually my best set-up for position opening. They show the price action confirming that probably large orders are filled in the direction of the trend.
