Roku: two milestones already hit, but the last bar raises a caution flag

Roku is at week 8 of a buy signal, with a 19% gain since entry and 2 of the 3 targets of our most advanced model already hit. The stop is at breakeven: risk is zeroed out. However, the last weekly bar shows sellers in an extremely dominant position and volumes contracting — a signal not to ignore with the next management window at week 10 just ahead.
