Pair Correlation Oscillator (Overlay)Pair Correlation Oscillator (Overlay)
Overview
This open-source TradingView indicator computes the Pearson correlation coefficient between the chart's instrument (Ticker A) and a user-selected instrument (Ticker B). The correlation is displayed as an oscillator within the range −1..+1:
+1 — perfect positive correlation
0 — no linear correlation
−1 — perfect inverse correlation
Key features
Default window: 500 bars (configurable)
Option to compute correlation on log returns (recommended for comparing different instruments)
Option to exclude the current unfinished bar (use previous completed bars only)
Overlaid line + histogram columns for immediate visual interpretation
Alert examples included (commented out) for high correlation thresholds
Inputs
Ticker 2 — the other instrument to compare against (Ticker 1 is always the chart symbol)
Correlation length — window in bars for the rolling correlation (default 500)
Use log returns — converts price series to log returns before correlation (recommended)
Exclude current bar — shift series by 1 to use only completed bars
How to use
Add the script to your chart and set Ticker 2 to the instrument you want to correlate with the chart symbol.
Choose Use log returns = true for price-to-price comparisons (it removes level bias).
Optionally enable Exclude current bar for more stable signals if you do not want the live unfinished bar affecting results.
Use the line/histogram and label shown on the chart to inspect correlation in real time.
Limitations & notes
Correlation measures linear relationship over the chosen window — non-linear relationships won't be captured.
Very different tickers (e.g., price scales, very low liquidity) may show noisy correlation; use returns and longer windows in such cases.
