Questions to Watch

Interpretation & Scenarios
Careful wording — scenarios to watch, not forecasts. The decision is the trader's.
⬆️ Continuation (up) — to watch· If it holds above SMA50 (-5.6%) and breaks out on volume above the window — historically similar zones tended to continue. Technical confirmation needed.
⬇️ Weakness (down) — to watch· Relative weakness vs QQQ, SPY, SMH.
· If a breakout fails or it closes below SMA50 / a nearby low on volume — risk of continued weakness. Watch for fading volume and relative weakness.
↔️ Range / no clear edge· No active Price-Time Confluence right now.
· Distance from 52w high: -11.9% · from 52w low: +24.5%.
· Without confirmation either way — no clear edge; waiting for confirmation is reasonable.
