Project Pegasus Spectra

Project Pegasus Spectra — Volume-Weighted Core is a dedicated pane-based indicator designed to visualize volume-derived buy/sell pressure, momentum states, and extreme flow events in a clean, professional layout. It translates standard OHLCV data into an orderflow-inspired structure using Pressure Candles, PA-FL Momentum (δ/ATR), an optional momentum heatmap, and optional context markers (Imbalance, Climax, Exhaustion).

The goal is not to generate trade signals, but to provide a stable, low-noise visual framework for understanding pressure, momentum, and intensity across different markets and volatility regimes.

Core Components

1) Pressure Candles (Synthetic Buy / Sell Pressure)

Spectra estimates buy and sell volume within each candle using a price-weighted volume distribution:

Buy volume ≈ volume × (close − low) / (high − low)

Sell volume ≈ volume × (high − close) / (high − low)

From this, synthetic pressure candles are constructed to highlight:

buy vs sell dominance within each bar

gradual pressure shifts

sudden pressure expansions or extremes

Pressure Style

Net – single candle showing net pressure (buy − sell)

Split Buy/Sell – buy pressure above zero, sell pressure below zero (clear dominance view)

Pressure Mode

Raw – fully reactive, unsmoothed pressure

Smooth body + raw wick – candle body is EMA-smoothed, while wicks preserve raw extremes
→ cleaner visuals without hiding pressure spikes

Visual Control

Multiple color presets (Match Palette, Neon, Ocean, Sunset, Classic, Midnight)

Optional fully custom colors

Independent body and wick transparency, allowing pressure to act as a subtle context layer rather than visual noise

2) PA-FL (Price-Adaptive Flow Line) Momentum — δ / ATR

PA-FL is the main flow engine of Spectra.
It computes a volume-adaptive baseline (EMA-style), optionally blended with VWAP, and measures momentum as baseline delta normalized by ATR.

Why δ / ATR?

Makes momentum comparable across:

different symbols

varying volatility regimes

different sessions and market conditions

PA-FL Features

Optional VWAP blend for session anchoring

Adaptive baseline length driven by relative volume

Optional Zero-Lag smoothing (ZLEMA) to reduce delay

Optional clamping to prevent rare spikes from dominating the scale

Visualization

Histogram + Line

Color intensity scales with |δ|

Optional regime tinting (trend vs range) for contextual awareness rather than hard signals

3) Momentum Heat Background (PA-FL Heatmap)

An optional background heatmap driven by |δ / ATR|.

Purpose:

Quickly visualize momentum intensity without reading exact values

Act as a situational backdrop, not a signal layer

Interpretation

Low heat → neutral / balanced phase

Rising heat → momentum expansion

Strong heat → impulse or extreme activity

Fully adjustable via:

minimum / maximum transparency

intensity scaling

gamma contrast

This allows anything from barely visible to clearly readable, depending on preference.

4) Display Normalization (Stable Axis)

When enabled, Pressure and Rolling Delta are normalized into a stable ±100-style range using percentile-based amplitude estimation plus a hard clamp.

Benefits:

consistent pane scaling across sessions and symbols

prevents single outlier bars from stretching the display

cleaner, professional multi-symbol workflows

Normalization affects display only, not internal calculations.

5) Rolling Delta (Optional Context)

An optional, subtle rolling delta line that shows cumulative pressure drift over a defined window.
The visibility scale affects display only and does not alter the underlying delta calculation.

Optional Context Markers (Sparse by Design)

Imbalance Dot

Marks bars where absolute delta exceeds a threshold:

automatic (average |Δ| × factor)

or manual (fixed value)

Use as a context alert, not a standalone entry trigger.

Climax Detector

Flags unusually large buy or sell volume relative to its average.

Typical use cases:

stop-run / liquidation-like activity

momentum kick-offs or exhaustion points

Exhaustion Filter

Combines:

high total volume relative to average

unusually small net delta

Often associated with absorption-like or exhaustion behavior, depending on market context.

Suggested Workflows

Clean Pro Layout

Pressure Candles ON with high transparency

PA-FL Histogram + Line ON

Heatmap ON (subtle)

Normalization ON

More Orderflow-Like Feel

Pressure Style: Split Buy/Sell

Smooth body + raw wick

Optional Climax markers

More Event-Focused Context

Enable Imbalance and Climax sparingly

Use Exhaustion only when specifically analyzing absorption behavior

Important Notes & Disclaimer

Spectra is based on OHLCV-derived volume estimation.
It is not true bid/ask delta, not footprint data, and not time & sales.

All markers and visual elements are informational, not trade signals.

Interpretation depends on symbol, timeframe, session, and data feed.

Always combine with market structure, levels, and risk management.
