Chronological: recent past → active → upcoming. The target date is the center of the watch window — it opens a few days before and stays relevant a few days after. 'Near a window' is context only, not a signal.

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
· Positive relative strength vs QQQ, SPY, SMH.
· Sharp rally recently — watch for follow-through.
· If it holds above SMA50 (+3.2%) 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
· Distance from 52w high: -36.3% · from 52w low: +54.2%.
· Without confirmation either way — no clear edge; waiting for confirmation is reasonable.
