Commonly abbreviated as RMI.

Is a momentum indicator.

Was developed by Roger Altman.

Is computed using close prices.

Returns one time series, which is the ratio of 14-period exponential moving averages for gains and losses over 5 periods, rescaled to be between 0 and 100.

FinancialIndicator["RelativeMomentumIndex",n₁,n₂] computes gains and losses over n₁ periods and period-n₂ moving averages. The first value in the time series occurs after periods.
