The Relative Momentum Index indicator was developed by Roger Altman and first introduced in the journal “Technical Analysis of Stocks & Commodities” in February 1993. The main objective of this indicator, according to the author, is to improve the quality of the classic RSI indicator readings if the price reaches overbought/oversold zones.
What is the Relative Momentum Index (RMI)?
The Relative Momentum Index actually measures the ratio of upward change versus the downward change in price over a given period of bars. The change for each bar is calculated for a given number of bars.
As the case with RSI, the RMI indicator also ranges from 0 to 100 and the 30 and 70 levels are considered as oversold and overbought zones respectfully. Technically, the RMI is analyzed the same way as the RSI. With Relative Momentum Index, simply you can look for buying opportunities when the price reaches around 30 level and you may look for selling opportunities when the indicator value approaches around 70.
Similarly, the Relative Momentum Index reading above 50 is taken as a bullish indication while below the 50 mark is considered as a bearish indication.
RMI Calculation formula
RMI = 100 * N / (H + B), where
N is the number of days;
H is the amount of change in positive closing prices for the period between today and N days ago;
B – the sum of the changes in negative closing prices for today and N days ago.
RMI Indicator Parameters
RMIperiod = 14
MOMperiod = 5
How to use the Relative Momentum Index (RMI)?
As a classic oscillator of technical analysis, the RMI indicator allows you to determine the following possibilities for use in trading:
Peaks and troughs
When the indicator reaches and crosses the level of 70 in a uptrend, this is an important signal that the price will not be able to continue the uptrend. The RMI indicator in this case, very clearly indicates the overbought zone, and immediately after the price reaches this area, a fall can begin.
If the indicator reaches and crosses the level of 30 in a downtrend, this is the primary signal that the price has finished forming a correction and will now be able to continue moving upward. In such a situation, an asset can be bought.
The RMI indicator can also generate price action signals, such as “triangles,” “flags,” and a “head and shoulders” pattern, in which a trader can work out even if this model has not formed on the price chart itself.
As an oscillator, the Relative Momentum Index allows you to see the divergence/convergence signals on the indicator line in comparison with price movements. Signals of this kind on the RMI indicator are the most important for decision making, as this signal gives an early sign of reversal and may give a high probability trade entry.
