Auto-Trend Finder (Pivot + ADX)

Inspired in part by LuxAlgo Trendlines with Breaks. Extended and enhanced for directional clarity and pivot-based precision.

🔍 What It Does
The Auto-Trend Finder (Pivot + ADX) is a smart trend-detection toolkit that combines:

Pivot-based swing detection (HH, HL, LH, LL)

ADX-filtered trendline projections

Custom slope estimation using ATR, Standard Deviation, Linear Regression, or a blended approach

Candlestick pattern detection for added confirmation (e.g., hammer, engulfing, shooting star)

📈 How It Works
1. Swing Detection
Uses ta.pivothigh / ta.pivotlow to mark major price turning points.

Labels pivots as Higher High (HH), Lower High (LH), Lower Low (LL), or Higher Low (HL).

Optionally overlays basic candle pattern names for visual context.

2. Trendline Logic
Connects successive pivot highs/lows with real-time trendlines.

Draws separate Uptrend and Downtrend lines with distinct colors.

3. Extended Projections
Projects extended dashed lines from the last pivot using slope formulas:

ATR-based (volatility)

Stdev-based (dispersion)

Linear Regression (trend best-fit)

Or a Combined slope using user-defined weights.

Color changes dynamically on breakout to visually signal momentum shifts.

4. ADX Trend Strength Filter
Optional ADX filter disables trendline updates unless directional strength exceeds a threshold (e.g. 20+).

Helps remove noise in sideways markets.

⚠️ Important Notes
Backpainting Warning: This script includes a backpainting setting (backpaint) that may cause lines to appear "reliably predictive" in historical data. Backpainting does not repaint once the pivot is confirmed, but it still reflects a post-fact state. Use this feature cautiously in live trading decisions.

Reused Code Attribution: Extended trendline concept and breakout color logic were inspired by publicly available open-source versions of LuxAlgo's trendline logic. Credit is given in the script comments and here as required.

🛠️ How to Use It
Adjust Pivot Length for swing detection sensitivity.

Toggle ADX filtering on or off to avoid choppy signals.

Choose your preferred Slope Calculation Method.

Use candlestick labels as potential entry signals near trendline retests or breaks.

✅ Why This Is More Than a Mashup
This tool integrates several separate technical methods into one cohesive, customizable framework:

It’s not just combining indicators, it’s engineering synergy between them.

The slope and ADX filtering mechanics dynamically adjust to trend strength.

Candlestick confirmation and labeling give visual, real-time trade confidence.

It enhances open-source logic by adding modular slope options, ADX gating, pattern labeling, and user control.
