What Is the Range Expansion Index?

The Range Expansion Index is a momentum-based indicator that evaluates how much the price range is expanding or contracting compared to previous periods. This simple yet effective concept allows traders to determine whether the market is:

Trending upward

Trending downward

Moving sideways (range-bound)

The indicator is displayed as a single oscillating line between 0 and 100, making it visually clear and easy to interpret.

How the Range Expansion Index Works

The REI calculates the range of price movement over a selected period and compares it with past ranges. The result is plotted as a line that fluctuates within predefined levels.

REI Levels Explained

Above 70: Indicates a strong uptrend

Below 30: Indicates a strong downtrend

Between 30 and 70: Indicates a range-bound or consolidating market

These levels help traders quickly understand current market conditions and adjust their strategies accordingly.

When REI moves above 70, traders can look for buy opportunities aligned with the uptrend.
