Strong Session SD Zones | ProjectSyndicateStrong Session SD Zones
Strong Session SD Zones automatically maps and power-ranks the session-based supply & demand zones that price keeps reacting to. It tracks each zone through its full life — formation, tests, breakout, and invalidation — scores it 0–10 from real interaction, and retains every session's zones for the last N sessions, so you can see exactly which levels each Asia / London / New York session left behind.
🎯 Power-Ranking System (0–10) — every zone earns a live score from four things: the impulse of the move that created it, the volume traded while it formed, the depth of the rejection wicks off it, and its freshness (how unmitigated it still is). An idle-decay lets ignored zones fade while respected ones stay strong, so the score always reflects current relevance.
🕐 Session-Aware Zones — instead of one undifferentiated cluster of levels, zones are batched by trading session and each one is tagged with where it was born (Asia, London, NY, Late). Pick Daily, Asian, London, New York, or a custom session as the boundary that starts each new batch.
🔁 Hold vs Broken States — each zone is shaded by type (supply = red, demand = green) and re-shaded the moment price invalidates it, with a ✗ marker on broken zones. You see at a glance whether a level is still defending or has flipped.
🎨 Strength-Sharpened Fill — strong zones render sharp and opaque while weak ones stay faint, so the chart visually shows which levels carry weight before you even read the score.
🏷️ In-Zone Strength Labels — every zone carries its grade inside it: stars, the X.X/10 score, a tier (FORMING → WEAK → MODERATE → STRONG → ELITE), the live retest count (R:), and its session — quality reads instantly without a separate panel.
🧹 Overlap Suppression — when a new zone would stack on an existing same-session zone, the two are merged into one clean band instead of cluttering the area, so each price region shows a single level.
⭐ Strong-Only Filter — hide everything below a score threshold; weak zones that never earn the score are discarded rather than kept, so the chart only carries proven levels.
🔔 Comprehensive Native Alerts — proximity alerts for supply and demand zones, a dedicated STRONG-zone proximity alert (configurable, e.g. 7/10+), plus new-supply and new-demand formation events, so you never miss a key level interaction.
⚙️ Uniform Zone Height — normalize every zone to one ATR-based thickness for a clean, consistent look, with a minimum-swing filter that ignores insignificant pivots.
🚦 Performance Guards — a sessions-to-display window and a max-zones-kept cap keep load times fast on long histories; retired zones are fully removed, not just hidden.
🔧 Fully Customizable — color palette, transparency, borders, label size, scoring weights, pivot sensitivity, max zones per session, decay settings, and invalidation method (close vs wick) — all adjustable.
🎯 Why this algo is unique — standard pivot tools flood the chart with equal-weight lines. Strong Session SD Zones filters, merges, and ranks them by session, then keeps only the zones that have proven they matter. It doesn't just show where a level was — it quantifies how strong it is from real interaction (impulse, volume, rejection, freshness), giving you a clear read on which zones are holding and which are likely to break.
🚀 Apply to Gold (XAUUSD), Forex, Crypto, and Indices on any timeframe. Pivot sensitivity, zone height, sessions shown, and the strong threshold adapt it from scalping to swing trading.
🎯 How to use this? Focus on zones rated 7/10 or higher — these have the highest probability of producing a significant reaction. Watch the hold-vs-broken state to judge whether a level is defending or has flipped, and use the proximity and strong-zone alerts to prepare entries or exits.
⚠️ IMPORTANT NOTICE: This indicator identifies high-probability supply & demand zones. It should NOT be used as a standalone signal for entering trades. Always use it alongside your own trading strategy, price action analysis, and other technical indicators to confirm setups and manage risk. Indicator

─────────────────────────────────────────────────────────────────────────────
This indicator takes a different mechanism:
Every level is scored across three independent factors, and only levels that pass a minimum confluence threshold are promoted as tradeable.
HOW THE SCORING WORKS?
─────────────────────────────────────────────────────────────────────────────
Each detected swing level starts with a base score of 1. Up to 3 additional
points are added based on the following conditions:
+1 The level falls inside a High Volume Node (HVN)
— meaning significant volume was traded at or near this price.
Price tends to slow down and react at levels where market participants
have a large amount of open positions anchored.
+1 The level originates from the Higher Timeframe (HTF)
— a daily swing high visible on a 5-minute chart carries more weight
than a local 5-minute pivot. HTF structure reflects institutional
positioning, not just retail order flow.
+1 The level is within a configurable tolerance of a psychological level
— round numbers and half-levels attract resting orders from both
discretionary and algorithmic participants. Confluence with a psych
level adds a fourth layer of confirmation.
Final score interpretation:
Score 1 → Plain swing (structural only, no confluence)
Score 2 → ★★ GOOD (one additional factor confirmed)
Score 3+ → ★★★ STRONG (two or more factors confirmed)
Labels are drawn directly on the chart at each qualifying level so you can
assess confluence at a glance without manually cross-referencing indicators.
DETECTION METHODS
─────────────────────────────────────────────────────────────────────────────
Swing Structure (Current TF)
Pivot highs and lows are detected using a configurable lookback length.
Resistance levels are drawn in red, support in teal.
Swing Structure (Higher TF)
The same pivot detection runs on a user-selected higher timeframe
(default: Daily). HTF lines are drawn thicker and solid to visually
separate them from current-TF swings. Their visibility is controlled
independently from the score filter.
Volume Profile Nodes
The lookback range is divided into price buckets and volume is accumulated
per bucket. Buckets exceeding the HVN threshold percentile are drawn as
gold highlight zones. Optionally, Low Volume Nodes (price gaps) can also
be displayed.
Psychological Levels
Round numbers are auto-detected based on the magnitude of the visible
price range — the indicator adapts whether you are trading a $0.001 token
or a $50,000 asset. Half-levels can be enabled optionally.
VISIBILITY CONTROLS
─────────────────────────────────────────────────────────────────────────────
All four level types have independent show/hide toggles:
☑ Show Higher Timeframe Swings — HTF structure lines
☑ Show Good Levels ★★ — score 2 levels only
☑ Show Strong Levels ★★★ — score 3+ levels only
☑ Show Psychological Levels — round / half numbers
Turning off Good and Strong levels leaves only raw unconfirmed swings
visible, which is useful for studying structure without score bias.

NOTES
─────────────────────────────────────────────────────────────────────────────
- Volume Nodes and score labels are redrawn on the last bar only to keep
performance efficient on long histories.
- Swing candidates are collected on every bar into persistent arrays, so
no pivots are missed regardless of when the indicator is loaded.
- The scoring system is additive and transparent — each contributing factor
is visible in the label type prefix (R, S, HTF·R, HTF·S), so you always
know which timeframe and direction a level belongs to.
- HTF line visibility is intentionally decoupled from the score filter.
A daily swing high will always show when HTF display is enabled, even if
its score does not reach the GOOD or STRONG threshold. Indicator
