Silence Indicator — NNFX Volatility-Only Adaptation [UTS]

🤫 Silence Indicator — NNFX Volatility-Only Adaptation 📉📈


💡 Overview
A refined volatility oscillator adapted from Trofimov’s classic Silence indicator (2009), reworked for NNFX methodology by removing the aggressiveness line and focusing solely on volatility. It highlights phases of sufficient market volatility with clear trend-change markers and colored fills for easy visual interpretation.


🔑 Key Features
• Single-Event Signals – Plots one green ▲ when volatility rises above aggressiveness (indicating active phase), one red ▼ when it falls below (indicating quiet phase).
• Colored Fill – Fills the area between volatility and aggressiveness lines: bright purple for high volatility, dark purple for low volatility phases.
• Volatility Focus – Unlike the original, aggressiveness is removed to emphasize volatility as the core signal in line with NNFX principles.
• Non-Repainting – Signals appear only once per trend change bar for reliability.


🚀 How to Use
Trend Bias: Bright purple fill (red) and ▲ marker signal phases with sufficient volatility favorable for trading. Darker fill (blue) and ▼ marker warn of quiet, potentially less tradable market conditions.
Entries/Exits: Use the single-event markers at trend changes to time entries and exits confidently.
Filters: Combine with other NNFX indicators like volume and trend filters for robust strategy building.
