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.
