TII - Trend Intensity Index [UTS]

📈 Trend Intensity Index (TII) – Single-Event Trend Signals at zero line according to NNFX recommendations

💡 Overview
A clear, rule-based oscillator that measures trend strength by smoothing price vs. moving-average deviations into a 0–100 scale. Features one-time crossover markers and colored fills for at-a-glance bias.

🔑 Key Features
• Single-Event Signals – Plots one green ▲ when TII crosses up through the midpoint, one red ▼ when it crosses down.
• Colored Fill – Fills between the TII line and the 50-line: green above, red below.
• Zero Line Indicator – Use zero line as trend threshold per NNFX best practices.
• Customizable – Choose smoothing length, MA period & type (SMA/EMA/SMMA/LWMA), price source, and overbought/oversold levels.

🚀 How to Use
Trend Bias: TII ≥ 50 bullish; TII < 50 bearish.
Entries/Exits: Use the single-bar ▲/▼ markers for clear, non-repainting signals.
Flat Market: Avoid trading when TII hovers around 50.
Filters: Combine with volume or volatility filters for enhanced signal quality.

🛠 Inputs
• Length: SMA smoothing of up/down deviations (default 30)
• MA Length: Baseline moving-average period (default 60)
• MA Method: SMA, EMA, WMA, VWMA, Hull, LSMA, and 20 more ...
• Price Source: Close, Open, High, Low, Median, Heiken Ashi, and much more ...


📊 Signals
• ▲ Green below bar → TII crossed above 50 (bullish)
• ▼ Red above bar → TII crossed below 50 (bearish)

🔔 Alerts
• “TII Bullish Cross” on crossover above 50 (or zero)
• “TII Bearish Cross” on crossunder below 50 (or zero)
• Supports “Once Per Bar Close” to avoid repainting

⚙️ Zero Line (NNFX)
Zero-line mode (TII – 50) to align with NNFX guidelines: treat values > 0 as bullish and < 0 as bearish, using zero for trend confirmation and exit rules.
