FVG Sweep Magnet Engine [PhenLabs]

• Displacement-validated FVG detection filters out micro-noise gaps that never attract price
• Liquidity sweep gate (BSL/SSL raid + rejection) must print before any magnet signal arms
• 0–10 quality score blends gap size, displacement strength, freshness, and volume impulse
• Clean visual hierarchy: soft FVG zones + single CE midline by default; neon only on MAG
• Partial-fill fade and full mitigation cleanup keep the chart honest as gaps get consumed
• Live FSME dashboard tracks bias, live gaps, best score, sweep state, and last signal

• Displacement FVG Engine: Detects classic 3-candle bullish/bearish imbalances only when the middle candle body clears an ATR displacement threshold and the gap clears a minimum ATR size filter
• Liquidity Rail Tracker: Maintains confirmed swing BSL/SSL pools as dotted rails and classifies wick-rejection raids that reclaim the level
• Magnet Confluence Gate: Arms a signal only when a fresh sweep window overlaps a live scored FVG that price re-enters with directional close confirmation
• Target Projector: Extends dotted neon target rays from the FVG midline by ATR multiple after a magnet print
• Regime Dashboard: Compact top-right table summarizing bull/bear FVG count, best score, sweep state, last signal, nearest magnet mid, and ATR

• Non-repaint pivot liquidity and confirmed-bar FVG logic suitable for alerts and live trading
• Configurable displacement, gap size, magnet window, min score, and target extension
• Bull cyan / bear magenta neon palette with independent fill, border, rail, and beam colors
• Optional faded mitigated FVGs for study mode, or hard-delete cleanup for clean charts
• Alertconditions for bull/bear magnets, BSL/SSL sweeps, and new displacement FVGs
• Works as a standalone SMC overlay or confluence layer on top of session/order-block tools

• FVG zones: Soft teal/red translucent boxes (high transparency so candles stay readable) with score on the right edge
• CE midline: Single thin dashed line at the gap center — no permanent multi-layer beam cage
• Neon on MAG only: Triple glow beam + TP ray appear only when a magnet signal arms
• MAG labels: Clear ▲ MAG / ▼ MAG tags offset above/below the bar (not stacked on wicks)
• Optional extras (off by default): liquidity rails and sweep diamonds for power users
• Signal highlight: Soft bar tint only on confirmed MAG bars
• Dashboard: Compact 6-row panel — Bias, Live Gaps, Best Score, Sweep, Last Signal

• Max Active FVGs — Default: 10 — Range: 2-40 — Keep low for a clean chart
• Displacement ATR Mult — Default: 1.25 — Range: 0.3-5.0 — Raise on noisy lower TFs
• Min Gap Size (ATR) — Default: 0.25 — Range: 0.05-3.0 — Higher = fewer, cleaner zones
• Require Displacement Candle — Default: true — Keep on for quality
• Max FVG Age (bars) — Default: 60 — Range: 10-300 — Expires stale magnets
• Magnet Window — Default: 18 — Range: 3-80 — Bars after a sweep for FVG entry confirm
• Min Score for Signal — Default: 5 — Range: 0-10 — Raise to 7+ for selective setups
• Show FVG Midline (CE) — Default: true — Single dashed CE line per zone
• Neon Beam Only on MAG — Default: true — Neon appears only on confirmed signals
• Show Liquidity Rails — Default: false — Optional; off keeps chart readable
• Show Sweep Diamonds — Default: false — Optional; off by default to reduce noise

• ICT/SMC traders waiting for liquidity raids into unfilled FVGs instead of blind gap fades
• Intraday index and futures traders (ES, NQ, YM) on 1m–15m seeking clean reversal confluence
• FX and crypto traders mapping displacement legs during London/NY expansion
• Prop-style discretionary traders who want scored setups with explicit invalidation (full gap fill)
• Content creators capturing high-contrast neon dark-chart screenshots for TradingView publish art

• FVG detection is geometric (3-candle imbalance) and does not use true order-book data
• Sweep logic uses confirmed swing pivots, so very fresh local highs/lows need pivot length bars to register
• High-volatility news spikes can create large displacement gaps that score well but fail if context is one-way trend
• Neon beams and boxes are object-limited; extreme settings (max FVGs + long age) can hit TradingView object caps
• This is a confluence overlay, not a complete strategy — always pair with risk rules and higher-timeframe bias

• Sweep-gated magnets: FVGs stay passive until liquidity is actually raided — reverse of “every gap is a signal” tools
• Scored gaps: Traders see why a zone matters (size, displacement, age, volume) instead of binary boxes
• Signal-first visuals: zones stay quiet until confluence arms — neon and TP only on MAG
• PhenLabs DNA: Liquidity + engine naming + dashboard, fused with this week’s dominant FVG/ICT community demand

1. Displacement scan: On each bar the engine checks for a 3-candle bullish or bearish FVG, requires the middle candle body to clear ATR × displacement mult, and rejects gaps smaller than ATR × min gap size
2. Score + draw: Qualifying gaps receive a 0–10 score and are rendered as translucent boxes with a three-layer neon midline beam and optional score label
3. Liquidity map: Confirmed pivot highs/lows become BSL/SSL rails; a sweep prints when price raids the level with sufficient wick and closes back through it
4. Magnet arming: For a limited bar window after the sweep, if price re-enters a live same-direction FVG that clears the min score and closes in the reclaim direction, a MAG signal fires
5. Projection + lifecycle: Dotted ATR targets extend from the magnet mid; partial fills fade the box, full fills or max age invalidate the gap and clean objects unless faded mode is enabled

💡 Note:
Use FSME as a visual decision-support layer for liquidity-to-imbalance workflows. Confirm higher-timeframe bias, define risk beyond the opposite side of the FVG or swept pool, and never treat magnet markers as guaranteed entries.
