Intraday Momentum Index (IMI): Complete Guide

Intraday Momentum Index (IMI) is a technical tool that merges features of both candlestick charts and momentum indicator to assist traders in determining any overbought or oversold positions in a trading period. Like RSI, IMI is a momentum indicator which, however, evaluates the connection between the open and close prices of a security rather than just price momentum. Intraday Momentum Index is frequently employed by intraday traders.

What is Intraday Momentum Index (IMI)?

The Intraday Momentum Index (IMI) is a momentum-based oscillator which helps to analyze intraday momentum. The Intraday Momentum Index takes into account the profits and losses generated in the trading day based on the difference between the opening and closing prices of the security.

The index varies between 0 and 100:

• Above 70 signals overbought situation.
• Below 30 signals oversold situation.

Just like any other momentum indicator, the Intraday Momentum Index is meant to be used together with other technical tools.

IMI Indicator Explained

The Intraday Momentum Index is an indicator that uses price momentum on a daily basis using intraday gain and loss.

Features of the indicator include:

• It utilizes momentum along with candlestick price action.
• It helps to identify short-term pressure on the stock market.
• It can help in identifying trend reversals.

Unlike other indicators, which consider only the closing price, the IMI considers the opening price as well.

Intraday Momentum Index Formula

IMI is calculated using the below formula:

IMI = (Sum of Up Days ÷ (Sum of Up Days + Sum of Down Days)) × 100

Where:

• Up Days = Closing Price − Opening Price (when Close > Open)
• Down Days = Opening Price − Closing Price (when Open > Close)

IMI is usually calculated over a certain look back period of days, for example, 14 days.

How to Calculate IMI

Calculating the Intraday Momentum Index includes the following:

1. Choosing the number of periods to be considered for backtesting purposes (usually 14).
2. Finding the difference between the opening and closing prices on any particular day.
3. Summing up all positive intraday movements.
4. Summing up all negative intraday movements.
5. Using the IMI formula.
6. Analyzing the result from 0 to 100.

In most cases, current trading platforms perform automatic calculations of the IMI, and the trader’s work is reduced to analyzing signals only.

IMI vs RSI (Relative Strength Index)

While they are both momentum oscillators, the Intraday Momentum Index and RSI vary from each other in terms of the way price action is measured.

While RSI has been popularly applied in different time periods, the Intraday Momentum Index has been developed especially for short-term price analysis.

How to Use IMI in Intraday Trading
