Session Volatility Radar — Volatility × Structure Cross-Analysis with an Adaptive Signal Engine

════════════════════════════════════════════════════════════════════════════════

PRODUCT OVERVIEW

Session Volatility Radar (SVR) is a professional cTrader indicator designed for 24-hour markets such as Forex and spot gold/silver.

SVR does not stop at “volatility is high/low.” It cross-analyzes:

- Volatility regime (ATR / ATR-Mean)

- Structure regime (EMA side + confirmed fractal swing structure)

Then it maps that context to practical signal behavior:

Entry framework (trend-aware):

- Low Volatility + Trend → PB pullback-to-EMA entries

- Structure Breakout + Trend Context → BO breakout entries

- No Trend Context → no entry signal

Exit framework (independent monitors):

- HV: volatility spike exit

- REV: structure reversal exit

- RES: HV + REV resonance exit

This two-axis model helps reduce one-dimensional decisions and keeps context visible in real time through the on-chart panel.

════════════════════════════════════════════════════════════════════════════════

WHY SVR IS DIFFERENT

1) Context first, then signal

Most tools report volatility only. SVR combines volatility and structure before signaling.

2) Session-native workflow

SVR overlays Asia / Europe / US session bands and IB ranges directly on chart, so session context is always visible.

3) Adaptive, not fixed-threshold logic

Volatility and swing thresholds are recalculated from recent data via adaptive methods (KMeans → Jenks → Quantile fallback).

4) SignalFib is part of logic, not decoration

SignalFib can participate in entry filtering and exit logic (PB limit / retrace exit / extension exit), not just drawing.

5) Practical panel for live decision support

Panel shows regime state, thresholds, session stats, and signal context without switching tools.

KEY FEATURES

────────────────────────────────────────────────────────────────────────────────

1. VOLATILITY × STRUCTURE CROSS-ANALYSIS

SVR evaluates market state through two synchronized dimensions:

- Volatility dimension: ATR / ATR-Mean classification into low / normal / high volatility regimes.

- Structure dimension: EMA-side trend + confirmed fractal swing structure for breakout and reversal context.

Three adaptive presets (Conservative / Balanced / Aggressive) provide one-click sensitivity control.

────────────────────────────────────────────────────────────────────────────────

2. SESSION BANDS — INSTANT INTRADAY CONTEXT

SVR draws configurable session bands on the chart background:

- Asia session: 9 hours

- Europe session: 5.5 hours

- US session: 9.5 hours

Session alignment is anchored to the standard Forex trading day (New York close) and mapped to chart time automatically.

Each band supports configurable height, opacity, and colors, with session range/high/low/open references for quick context reading.

Historical session display supports up to 90 trading days.

────────────────────────────────────────────────────────────────────────────────

3. INITIAL BALANCE (IB) — EARLY SESSION STRUCTURE

IB is configurable by:

- IB Block Size (minutes), default: 30

- IB Block Count, default: 2

SVR keeps IB visible after the opening window, helping track continuation vs. rejection behavior through the full session.

────────────────────────────────────────────────────────────────────────────────

4. SIGNAL ENGINE (ENTRY + EXIT)

Entry side:

- PB (pullback): low-volatility trend pullback entries toward EMA

- BO (breakout): structure breakout entries, with default high-volatility filter enabled

- Optional M5 signal projection to current timeframe

Exit side:

- HV: exit on volatility spike

- REV: exit on reversal structure (with confirmation options)

- RES: exit only when HV and REV converge

Optional controls include pyramiding, reversal confirmation, and reversal cross filter mode.

────────────────────────────────────────────────────────────────────────────────

5. SIGNALFIB — CALCULATION-ALIGNED FIBONACCI

SignalFib can be used for:

- PB depth limiting (entry filter)

- Retracement-based exit

- Extension-based target exit

- Optional anchor updates from confirmed fractal ratchet (when enabled)

Displayed SignalFib levels are visual toggles only; signal calculation follows engine logic.

────────────────────────────────────────────────────────────────────────────────

6. INTERACTIVE PANEL + HISTORY MANAGEMENT

- Live panel controls for key toggles and presets

- History loading status and degradation visibility when data is insufficient

- Local cache with retention controls for smoother operation

- LocalStorage-based state persistence (no external data transfer by indicator logic)

IMPORTANT NOTES

ADAPTIVE THRESHOLDS

Actual thresholds used by the signal engine are adaptive values derived from recent data windows; defaults are starting anchors.

SESSION TIMING

Sessions follow a Forex-day anchor (New York close) and are auto-mapped to chart time. For continuous markets, 24/7 handling is supported via Market 24/7 Mode.

HISTORY LOADING

SVR can request additional history when needed and exposes loading/degradation state in panel diagnostics.

NON-REPAINTING SCOPE

Confirmed fractal swings and confirmed historical signals do not repaint. The still-forming bar and active in-progress state can update as new data arrives.

INDICATOR, NOT A BOT

SVR is an analytical indicator, not an automated trading robot (cBot). It does not place orders, manage positions, or execute risk controls for you.

TRIAL

A 7-day trial version is available in cTrader Store.
