DislikedThis may be a very useful observation.
The "cup" pattern like you call it makes total sense if you take a look behind the scenes. First high volume is needed to stop the current downtrend + Smart Money is opening their hands and are collecting.
After ranging sitewards increasing volume is needed again to push PA outside the range and start the new run.
I will watch out for more CUPsIgnored
This pattern cought my eye yesterday when we had a similar volume formation during the long Sonic R setup on EU.
