Rank Correlation Index (RCI) – FX Replay Guide

The Rank Correlation Index (RCI) on FX Replay helps you spot when the market is out of sync with itself — a sign that a reversal or momentum shift might be around the corner. Think of it like a smarter RSI that looks at time and price together.

How to Use RCI in FX Replay

Watch for Extremes:

• RCI above +80? Market could be topping out — look for bearish setups
• RCI below -80? Market may be bottoming — look for bullish setups

Look for Crossovers:

• When RCI crosses the zero line or its moving average, it can hint that momentum is flipping
• Use this alongside Market Structure or Chop Zone to confirm early

Pair it for Power:

• RCI is great with Inside Bar, FVG, or PO3° to confirm high-probability reversals
• Example: RCI hits +90, and PO3° shows high timeframe exhaustion — boom, reversal entry

Tune the Settings:

• Try 9, 14, or 20-period RCI settings
• Select “close” as your price source for most cases — but experiment if needed for precision

Backtest with Replay:

• Use Replay Mode to see how RCI responds near key highs/lows
• Watch for consistent divergence patterns that signal reversal zones
