Former ArcSE has had a great rund. Parabolic arc patterns can be volatile when they hit the landing pad. Most of the time they do not shoot back up like a rocket as they did on the first go around. ROKU is giving it shot though. Any pattern can fail.
Parabolic arcs usually fall between 50 to 62% in a bull market. The fall to the bottom is not usually as hasty as the rise to the top. Volatility is often extreme. Parabolic arcs are long term patterns and I find them difficult to trade.
No recommendation
I think i see a head and shoulders pattern or an ugly top as well with neckline at 204ish, tall structure. Long way to go to even get near the neckline. I suppose a lot depends on Mr Market. This is a bull market so far, so ugly tops often form pretty bottoms and go back up. SE has broken the neckline once, but not for long.
