Range Expansion Index


You can now download the Range Expansion Index indicator for free on AtoZ Markets indicators gallery.

Range Expansion Index (MetaTrader indicator) is a relative oscillator indicator that measures the pace of the price changes and signals overbought/oversold states if the price demonstrates weakness or strength. It was developed by Tom DeMark and explained in his book The New Science of Technical Analysis. The value of the indicator changes from -100 to +100. REI is an enhanced oscillator because it tries to remain calm during the range trading and indicates signals only when the significant peaks or bottoms are spotted. You can download this indicator both for MT4 and MT5.

Input parameters

REI_Period (default = 8) — the period of the indicator. Increase the value for less but more precise signals. Decrease it for more but inaccurate signals. It’s not recommended to change this parameter.

How to trade with Range Expansion Index

Tom DeMark suggested using the default period of 8. When the price goes above level 60 and the declines below it, the bearish signal is given. When the price goes below level -60 and then rises above it, the bullish signal is given. I find this indicator rather inaccurate (like all oscillators), but on the lower timeframes it can be quite useful.
