The classic technical analysis does not care about this kind of breakouts. According to the classic TA, these patterns are considered as negated or invalid, or in the worst case as nonexistent.
However, our pattern statistics allow us to estimate the range of this kind of breakouts, based on the historical data, even if the technical analysis doesn't have a suitable measure rule. Therefore, it would be awkward if we didn't offer such feature, because from the technical point of view, there is no difference in estimating the statistical target for any pattern type in either breakout direction. What is more, it allows us to collect reliable statistics for pattern confirmations and invalidations (i.e. to answer a question what breakout direction you should expect for the specific pattern type under certain conditions, regardless of it is a top, bottom or other pattern type).
