RSI Z-score | Lemniscuss

🧠 Introducing RSI Z-Score (RSI-Z) by Lemniscuss
🛠️ Overview
RSI Z-Score (RSI-Z) is a momentum-based market condition detector that transforms the classic Relative Strength Index (RSI) into a standardized volatility framework.
By applying Z-Score normalization to the RSI, this tool allows traders to identify statistically significant deviations in momentum — cutting through noise and highlighting high-probability turning points.
RSI-Z is optimized for trend inflection detection and overextension spotting, providing both visual clarity and actionable trade signals with dynamic labeling and optional bar coloring.
🔍 How It Works
1️⃣ RSI Foundation
The system starts with a standard RSI calculation on a user-defined source and length (default: 45).
2️⃣ Z-Score Normalization
The RSI values are standardized by subtracting their mean and dividing by the standard deviation over the same lookback.
This converts RSI into a statistical measure — revealing how many standard deviations current momentum is from its mean.
3️⃣ Threshold Logic
Two customizable thresholds define actionable zones:
• Long Threshold → Signals bullish momentum shifts when crossed upward
• Short Threshold → Signals bearish momentum shifts when crossed downward
4️⃣ Signal State Tracking
A state variable locks in a bias (Long / Short / Neutral) until an opposing trigger appears, ensuring clear and consistent market bias mapping.
✨ Key Features
🔹 Statistically Driven Momentum Detection — Moves beyond fixed RSI overbought/oversold levels by using standard deviations for adaptive accuracy.
🔹 Customizable Thresholds — Fine-tune long/short triggers for different volatility environments.
🔹 Clear Visual Feedback — Candle coloring and signal labels make trade setups instantly recognizable.
🔹 Overlay-Friendly — Works directly on your main chart or in a separate pane.
⚙️ Custom Settings
• Source: Price stream for RSI calculation (default: close)
• RSI Length: Lookback period for RSI & Z-Score (default: 45)
• Long Threshold: Z-score value for bullish signal (default: 1)
• Short Threshold: Z-score value for bearish signal (default: -1.9)
• Long/Cash Signal Labels: Toggle for "Long"/"Short" markers
• Bar Coloring: Toggle for trend-based candle coloring
📌 Trading Applications
✅ Trend Reversals → Spot statistically significant shifts in momentum before traditional RSI signals trigger
✅ Overextension Monitoring → Identify when momentum has deviated too far from the mean
✅ Mean Reversion Setups → Use extreme Z-score values as potential reversion points
✅ Bias Confirmation → Combine with trend tools for higher conviction entries/exits
📌 Conclusion
RSI-Z by Lemniscuss offers a clean, statistics-backed upgrade to the classic RSI.
By framing momentum in standard deviation terms, it empowers traders to separate normal fluctuations from truly significant market moves — making it a valuable tool for both trend traders and mean reversion specialists.
🔹 Summary Highlights
1️⃣ Statistical upgrade to RSI for higher-quality signals
2️⃣ Threshold-based, customizable long/short triggers
3️⃣ Visual candle coloring & signal labels for clarity
4️⃣ Adaptable to trend, swing, or intraday strategies
📌 Disclaimer: Past performance is not indicative of future results. No indicator guarantees profitability — always test and manage risk appropriately.
