TraderDemircan Trend Based Fibonacci + XABCD Formation
Description
TraderDemircan Trend-Based Fibonacci + XABCD Formation is an original open-source indicator that combines trend-based Fibonacci projections with an automated XABC structure detection engine.
The script focuses on identifying swing high → swing low transitions in a downtrend, generating Fibonacci levels and projecting a potential C-target extension based on harmonic geometry.
This indicator is designed for traders who want a clearer visual structure of how retracement, continuation, and harmonic projections interact inside trending markets.
🧩 What the Script Does
1. Detects the Most Recent X–A Swing (Trend High → Trend Low)
The indicator automatically scans a user-defined lookback range to identify:
X: Most recent significant swing high
A: The lowest low after X within the lookback window
This creates the foundational XA leg used for both Fibonacci levels and harmonic projections.
2. Determines a Dynamic B-Point Retracement
The script measures the market’s current retracement relative to the XA leg:
If price retraces below 0.50, B becomes the 0.50 level
If price retraces above 0.50, B becomes the 0.382 level
The algorithm ensures proper harmonic logic by validating that price stays below the B-level, preventing invalid structures.
3. Projects a Harmonic C-Target
Using harmonic extension logic, the script calculates:
C = B − (X − A)
This projects a symmetrical continuation leg relative to XA, giving traders an estimated “C-completion zone."
The C-target is displayed visually and numerically in an on-chart info table.
4. Plots Full Trend-Based Fibonacci Levels
The indicator draws Fibonacci levels from 0.0 to 2.618
Users can independently enable/disable each level, adjust line styling, choose color themes, add price labels, and display retracement percentages.
🎨 Visualization & Usability
The script includes:
Clean, customizable Fibonacci layout
Optional price labels & percentage labels
Extendable line options
Highlighted XABC structure
Dashed projection lines for the C-target
A compact info table showing X, A, B, C prices
This helps traders visually track structural market progression with clarity.
📘 Conceptual Foundation
This indicator is based on:
Trend-retracement logic using classic Fibonacci ratios
Structural swing identification
Basic harmonic symmetry (XA → BC projection)
Downtrend-based continuation expectations
It does not attempt to identify full harmonic patterns (like Gartley, Bat, or Crab), but instead focuses on the trend-based XABC segment and projected continuation targets.
🔧 Inputs Overview
Key user controls include:
Lookback window for pivot detection
Individual Fibonacci level visibility toggles
Color controls & line styling
Label display options
XABC formation display toggle
C-target on/off
All parameter names in the script are English; if translations appear in inputs, their English equivalents are included here to comply with TradingView publication rules.
⚠️ Limitations & Notes
The indicator does not predict future price direction.
It does not repaint, but pivot detection naturally depends on completed bars.
The C-projection is a geometric estimate, not a trading signal.
No forward-looking or non-causal data is used.
This tool is intended for structural analysis, not automated strategy execution.
📎 How to Use It
Add the indicator to a clean chart.
Observe the most recent X → A swing.
Watch how price interacts with 0.382 / 0.5 retracement to form the B-point.
Use the projected C-target as a reference zone for potential continuation completions.
Combine with your own trend, momentum, or volume methods for confirmation.
✔ Originality
This script is fully original and not derived from any pre-existing public script.
It combines:
Automated dynamic trend-based Fibonacci framework
Custom XABC structure detection
Harmonic-style C projection logic
Fully customizable visualization system
The indicator is intended to add meaningful analytical value to the community beyond standard Fibonacci tools.
