How to trade it?
For downward breakouts, use the lowest valley in the pattern as the target. For upward breakouts, consider the difference between highest and lowest valley as height for the target from the highest valley price.
Since the bottom trendline slopes upward, do not short this pattern at the top trendline. Go long at the bottom when price bounces off the bottom trendline.
