Seven or more down sessions in ten is a selloff with some persistence to it. A close above the previous day's high is the smallest unit of the sellers losing control. The two conditions want to be counted separately: the run is described with `count` so that one green bar inside the decline does not disqualify it, and the turn is the current bar, checked exactly. It fires rarely, and that is the point. What comes back is the day's earliest reversal candidates. Plenty of oversold stocks are absent from it.
