RSI Z-Score + Table

How It Works

RSI Calculation
The standard RSI is computed over a user-defined period (default: 14), measuring the strength of recent price movements.

Z-Score Transformation
The RSI is then normalized using the Z-Score formula:

Z = (RSI - Mean) / Standard Deviation
This highlights whether RSI is unusually high or low compared to its historical behavior.

Smoothing
An optional EMA is applied to the Z-Score for smoother and more reliable signals (default: 10-period smoothing).

Z-Score Table
A real-time value of the RSI Z-Score is displayed in a table in the top-right of the indicator pane.

The value is clamped between +2 and -2

+2 aligns with strong overbought RSI conditions

-2 aligns with strong oversold RSI conditions

How to Use It

Buy Signal Potential: When the Z-Score drops below -1.5 or -2 → statistically oversold RSI

Sell Signal Potential: When the Z-Score rises above +1.5 or +2 → statistically overbought RSI

Use in Confluence: Combine with price action, trend filters, or other Z-Score indicators (e.g. OBV, VWAP, VIX) for SDCA or mean-reversion strategies
