Didi Index Pro – NNFX Trend Indicator [UTS]

📈 Uber Didi Index Pro – NNFX Trend Indicator
A Top 100 NNFX-Compliant Trend Indicator – Refined for Rule-Based Traders

This enhanced Didi Index is a purpose-built trend indicator optimized for No Nonsense Forex (NNFX) systems. It reimagines the classic Brazilian Didi Index with powerful upgrades designed for serious, rules-based trading.

🔍 What Makes This Version Unique?
✅ NNFX-Adjusted Logic
• Removes short/fast MAs to reduce noise
• Designed to work only with long-period moving averages – as per VP’s recommendations

🔁 Inverted & Zero-Centered
• Deviations are plotted relative to the medium MA baseline at zero
• Inverted formula offers better signal clarity (e.g., rising above zero = uptrend)

🎛️ Customizable with 25+ Moving Average Types
• Choose SMA, EMA, WMA, VWMA, Hull, LSMA, and more
• Tune each line individually to match your system rules

📢 Alerts Built In
• Set alerts for crossovers, entering/exiting zones, or custom signal events
• Works as a primary confirmation, secondary confirmation or even exit indicator

🎯 Clean Signals, Fast Readability
• Removed the "Curta" and relies on the better "Longa" line relative to a zero centered "Media" line
• Great for confirming higher timeframe trends or filtering false entries

🕰️ History & Context
Originally developed by Brazilian trader Odir “Didi” Aguiar, the Didi Index compares short, medium, and long moving averages to spot market compression and expansions. This version repurposes the idea for trend-following, not mean reversion, and fully aligns with NNFX methodology.

📎 How to Use in NNFX Systems
Use this indicator as part of your C1 or C2 (confirmation) indicator:

When the Longa line is above zero → Bias = Long

When the Longa line is below zero → Bias = Short

Avoid trades when both lines are tightly compressed near zero

✅ Designed by traders who follow the rules.
✅ Built for traders who want clarity, consistency, and compliance.
