📊 FVG Quality Scorer | Flux Charts
Indicator Analysis · English Version · PineScript v6
1.1 Core Concept
The FVG Quality Scorer evaluates every Fair Value Gap (FVG / imbalance zone) across four independent scoring axes, each worth a maximum of 25 points, producing a weighted composite score of 0–100 and an A/B/C/D grade. Rather than treating all FVGs equally, the indicator surfaces only the highest-quality setups by filtering out low-grade zones from the chart.
A bullish FVG forms when low > high[2] (gap between the current bar's low and the candle two bars back's high). A bearish FVG forms when high < low[2]. These are standard three-bar imbalance zones.
💡 Design principle: All scoring thresholds are normalized — axis weights
are user-configurable and sum-normalized to 100, so changing one weight automatically
rebalances all others. Per-grade minimum requirements can independently gate each axis,
ensuring an "A" grade cannot be earned by strength in only one dimension.
1.2 Key Features
- 📐 4-Axis scoring — Displacement · Volume Delta · Contextual · Structural, each 0–25 pts
- 🏆 A/B/C/D grading — configurable per-axis minimums and required-axis gates per grade
- ⚖️ Weighted composite — user-defined axis weights, sum-normalized to 100
- 📊 LTF volume delta — intrabar bull/bear volume ratio via request.security_lower_tf
- 🕰️ HTF FVG nesting — checks whether current FVG sits inside a higher-timeframe FVG for confluence
- 🎯 Killzone awareness — bonus points for FVGs formed during Asian/London/NY sessions
- 📈 BOS / CHoCH tracking — rewards FVGs aligned with a recent break of structure
- 🔄 State machine — Fresh → Tested / PartiallyFilled → Mitigated, with optional historic display
- 🖼️ Deferred drawing — all boxes and labels redrawn only at barstate.islast for performance
- 📋 Dashboard — per-grade active/total counts, average fill time, nearest A-grade distance
- 🚨 Alerts — new A-grade and new B-grade FVG detection
1.3 How to Use
⚙️ Input Parameters| Parameter | Default | Description |
|---|---|---|
| swingLen | 5 | Bars each side to confirm a swing high/low for market structure |
| atrLen | 14 | ATR period for displacement scoring |
| ltfTf | "1" | Lower timeframe for intrabar volume delta (e.g. "1" = 1-minute) |
| htfTf | "60" | Higher timeframe to check for FVG nesting confluence |
| rangeLb | 50 | Lookback bars for premium/discount range calculation |
| sweepWin | 5 | Window in bars to look back for a liquidity sweep event |
| bosLb | 20 | Max bars since last BOS/CHoCH to award structural bonus points |
| emaLen | 50 | EMA period for trend alignment check |
| dispW / volW / ctxW / strW | 25 each | Relative weights for each axis (normalized to 100 total) |
| minGrade | "C" | Hide FVGs below this grade from the chart |
| mitMethod | "Wick" | Wick: mitigated when wick crosses zone; Close: when close crosses |
| showHist | false | Show mitigated FVGs as gray boxes (historical mode) |
- Grade A box (green) — highest-quality FVG, all four axes strong, treat as primary setup zone
- Grade B box (teal) — solid setup, good displacement + volume, minor structural/contextual gap
- Grade C box (amber) — moderate quality, use with additional confirmation
- Grade D box (gray) — low quality, avoid or ignore unless grade filter hides them
- Score label — numeric 0–100 composite score shown at right edge of each box
- Faded box — PartiallyFilled state (price entered zone but didn't exit the other side)
- Gray box — Mitigated (showHist must be on to see)
- Set minGrade = "B" for high-conviction setups only — reduces chart clutter significantly
- Enable alerts for "New A-Grade FVG" to catch top-tier setups in real time
- Use dashboard "Avg Fill Time" per grade to calibrate hold periods: A-grade FVGs typically survive longer
- Combine with HTF bias: A-grade FVGs nested inside HTF FVGs receive the full 8-pt HTF bonus
- On lower timeframes, reduce ltfTf accordingly (e.g. use "1" on 5-minute charts)
1.4 How It Works (Output → Input)
🖥️ Output — What Appears on Chart- Colored boxes (A=green / B=teal / C=amber / D=gray) spanning the FVG price zone
- Grade letter centered inside each box
- Score label (0–100) at the right edge with hover tooltip showing per-axis breakdown
- Dashboard panel: per-grade active/total/avg-fill-time + nearest A-grade distance
All visual objects are redrawn from scratch on every barstate.islast tick: previous boxes/labels are deleted, then the full fvgArr is iterated. FVGs below minGrade are skipped; mitigated FVGs are skipped unless showHist = true. Box color fades for PartiallyFilled state and turns fully gray for Mitigated state.
🔄 Tier 5 — State Machine (Lifecycle)Every bar, all non-mitigated FVGs in fvgArr are checked:
| Transition | Condition |
|---|---|
| → Mitigated | Wick method: low < fvg.bottom (bull) / high > fvg.top (bear); Close method: close crosses zone |
| → PartiallyFilled | Price enters zone but hasn't fully crossed: close < top and close > bottom |
| → Tested | Price touched zone boundary from outside: low ≤ top and low[1] ≥ top (bull) |
| PartiallyFilled → Tested | Price exits the zone without full mitigation |
New FVGs are pushed into fvgArr (array of FVG UDT objects). When the array exceeds 200 entries, the oldest entry is shifted out to prevent memory overflow. Dashboard counters (aTotal, aBarsSum, etc.) accumulate lifetime statistics and are never reset.
🏆 Tier 3 — Grading & Weighted Total
Weighted total:
weighted = (dsp/25)×dW + (vol/25)×vW + (ctx/25)×cW + (str/25)×sW
total = min(round(weighted × 100/wSum), 100)
Grade assignment — evaluated A → B → C → D in order; first passing grade wins. Each grade checks both a minimum per-axis score AND an optional "required" flag:
| Grade | Default Min per Axis | Required Axes |
|---|---|---|
| A | 12/25 each axis | All 4 required |
| B | 12/25 each axis | Displacement + Volume required |
| C | 8/25 each axis | Displacement + Volume required |
| D | (fallback) | None required |
| Component | Max Pts | Logic |
|---|---|---|
| Body-to-range ratio | 10 | ≥85% → 10 · ≥70% → 7 · ≥55% → 4 · else → 0 |
| ATR multiple | 10 | Body size ÷ ATR: ≥2× → 10 · ≥1.5× → 7 · ≥1× → 4 · else → 0 |
| Consecutive alignment | 5 | Candles at bar[2] and bar[0] both aligned with FVG direction: 5 · one aligned: 2 · none: 0 |
| Component | Max Pts | Logic |
|---|---|---|
| LTF bull/bear dominance | 12 | Intrabar directional volume ratio on displacement candle: >75% → 12 · ≥60% → 8 · ≥50% → 4 |
| Relative volume | 8 | Bar volume ÷ 20-bar SMA: >2× → 8 · ≥1.5× → 5 · ≥1× → 2 |
| Volume rising into gap | 5 | vol[1] > vol[2] > vol[3] → 5 pts |
| Component | Max Pts | Logic |
|---|---|---|
| Premium / Discount zone | 8 | Bull FVG in discount half (below 50% of rangeLb range) = 8 pts; above midpoint = gradient 4→0 |
| HTF FVG nesting | 8 | Current FVG fully inside an HTF FVG of same direction = 8 pts |
| Post-sweep proximity | 5 | Liquidity sweep (wick beyond swing then close back) within sweepWin bars = 5 pts |
| Killzone timing | 4 | FVG formed during Asian / London / NY AM / NY PM session = 4 pts |
| Component | Max Pts | Logic |
|---|---|---|
| Market structure bias | 10 | HH+HL (bull struct) with bullish FVG → 10 · opposing struct → 0 · neutral → 2 |
| EMA alignment | 8 | Bull FVG and close > EMA50 → 8 · Bear FVG and close < EMA50 → 8 · else → 0 |
| Recent BOS/CHoCH | 7 | BOS within bosLb bars, aligned direction → 7 · misaligned → 0 · no recent BOS → 2 |
