Session Volume Spike Detector

Session Volume Spike Detector (Buy/Sell, Dual Windows, MTF + Edge/Cooldown)
What it does
Detects statistically significant buy/sell volume spikes inside two DST-aware Mountain Time sessions and projects 1m / 5m / 10m signals onto any chart timeframe (even 1s). Spikes are confirmed at the close of their native bar and are edge-triggered with optional cooldowns to prevent duplicate alerts.
How spikes are detected
Volume ≥ SMA × multiplier
Optional jump vs recent highest volume
Optional Z-Score gate for significance
Separate Buy/Sell logic using your Direction Mode (Prev Close or Candle Body)
Multi-Timeframe (MTF) display
Shows 1m, 5m, 10m arrows on your current chart
Each HTF fires once on its bar close (no repaint after close)
Sessions (DST-aware, MT)
Morning: 05:30–08:30
Midday: 11:00–13:30
Spikes only count inside these windows.
Inputs & styling
Thresholds: SMA length, multipliers, recent lookback, Z-Score toggle/level
Toggles for which TFs to display (chart TF, 1m, 5m, 10m)
Per-TF colors + cooldowns (seconds) for Any TF, 1m, 5m, 10m
Alerts (edge + cooldown)
MTF Volume Spike (Any TF) — fires on the first qualifying spike across enabled TFs
1m / 5m / 10m Volume Spike — per-TF alerts, Buy or Sell
Recommended: set alert Trigger = Once per bar close. Cooldowns tame “triggered too often” warnings.
Great with
FVG zones, bank/insto levels, session range breaks, and trend filters. Use the MTF arrows as a participation/pressure tell to confirm or fade moves.
Notes
Works on any symbol/timeframe; best viewed on 1m or sub-minute charts.
HTF spikes appear on the bar close of 1m/5m/10m respectively.
No dynamic plot titles; Pine v6-safe.
Short summary (≤250 chars):
MTF volume-spike detector for intraday sessions (DST-aware, MT). Projects 1m/5m/10m buy/sell spikes onto any chart, with edge-triggered alerts and per-TF cooldowns to prevent duplicates. Ideal for spotting institutional participation.
