Questions to Watch
Is there a failed breakout above the window?Did an abnormal reversal candle appear?Is there an abnormal volume spike?Is the advance stalling (no follow-through)?Is short-term support breaking?Any change in relative strength vs QQQ/SPY/SMH?Is the leading sector weakening?
Interpretation & Scenarios
Careful wording — scenarios to watch, not forecasts. The decision is the trader's.
⬆️ Continuation (up) — to watch· The broad trend (by MA stacking) is still up.
· Positive relative strength vs QQQ, SPY, SMH.
· Sharp rally recently — watch for follow-through.
· If it holds above SMA50 (+12.2%) and breaks out on volume above the window — historically similar zones tended to continue. Technical confirmation needed.
⬇️ Weakness (down) — to watch· 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: -1.5% · from 52w low: +81.7%.
· Without confirmation either way — no clear edge; waiting for confirmation is reasonable.
