Range Expansion Index (REI) is a custom oscillator indicator coded by EarnForex.com. The indicator was developed by Tom DeMark and first presented in his book The New Science of Technical Analysis. REI provides signals when the indicator crosses either level 60 or -60.
This implementation of the Range Expansion Index concept includes all alert types supported by the MetaTrader platform.
