PRCT Cup Formation

Hello Pat, it seems I have a cup question every week, but believe my below question is different in nature compared to last week’s cup question. In the key list for tomorrow we have $PRCT at trigger price $46.7 where it formes a cup from HOD on 8/11/22. I wonder why we use the “high” cup at $46.7 as trigger price and not a lower cup at $46.13 or $45.51. I understand it is unproductive chasing small movements (and so it makes sense to wait for the high cup), but in the case of $PRCT we do see HOD volume on the last half hour prior to market close. As such, could one make the argument to focus on this positive momentum by working with the lower cup trigger prices?
Kind regards,
Adam
