DI+ Trend Tracker & Prediction (v6)

DI+ Trend Tracker & Prediction – Pine Script v6
🔍 Overview
This custom TradingView indicator focuses exclusively on the +DI (Positive Directional Indicator) component of the ADX (Average Directional Index) system. It tracks recent DI+ values, analyzes trend strength and direction, and applies a simple predictive model to estimate DI+ for the next trading day.

🧠 Key Features
✅ 1. DI+ History Table (Last 4 Days)
Displays DI+ values for the past 4 completed bars.

Helps traders observe momentum and directional strength in a structured view.

📈 2. Percentage Change Calculations
Daily % Change: Shows change between the current DI+ and the previous day.

Average % Change (3 Days): Measures average change over the last 3 sessions to identify the directional consistency.

🔮 3. Predictive DI+ Estimation
Uses a linear regression (ta.linreg) over the last 4 DI+ values to estimate the next day’s DI+ reading.

This is a simple "AI-style" statistical model, providing a forecast for tomorrow’s directional strength.

📉 4. Buy/Sell Signal Generation
Buy Signal: Triggered when DI+ rises steadily over 3 days.

Sell Signal: Triggered when DI+ drops steadily over 3 days.

These signals are shown both in the table and directly on the chart with triangle markers.

📋 5. Clean Table Display
The indicator uses a top-right table to clearly present:

4-day DI+ history

Daily and average percentage changes

Predicted DI+ value
