Intraday Momentum Index

Key Highlights

  • Utilizing candlestick charting and relative strength indexing (RSI), the intraday momentum index (IMI) creates trading indications.
  • Instead of focusing on how the open/close price changes from day to day, the IMI examines the relationship between a security's open and close price during the day.
  • Experts could utilize the IMI to determine when security exceeds its capacity or is underwhelmed.

The Intraday Momentum Index, or IMI meaning, is a technical analysis indicator that monitors the momentum of price movements in one day's trading. In order to create a comprehensive view of market strengths and weaknesses, it consolidates data on prices and volumes. Day traders are the primary market participants using this indicator to spot potential entry and exit points on volatility markets.

In early 1990, Tushar Chande, a well-known businessman and author, developed the Intraday Momentum Index. Chande has tried to create an indicator that will provide reliable insights into intraday price movements, making it more effective than other momentum indicators targeting longer periods.

As a tool to identify short-term trends, capture price swings, and generate buy or sell signals, the IMI is widely used by traders and investors. It is especially useful in fast-moving markets, where rapid shifts in momentum can give rise to potential trading opportunities.

The components of the intraday momentum index are mentioned below.

Price Changes

1. Very high and very low prices The high and low price of the security on that trading day shall be taken into account in the IMI calculation. These values shall be expressed in the sum of the highest and minimum prices at which the security has been traded within a specific period.

2. Prices at the closed and open In addition, IMI uses prices at the close and open markets for security to gauge overall price fluctuations during the trading day. The close price denotes the security's final trading price for the day, whereas the open price denotes the first exchanged price once the market opens.

Trading Volume

1. Relationship with Price Changes The IMI's most important factor is trading volume, which shows the level of interest and trading activity in a given security. There is frequently a significant degree of market belief behind price movements when there is a substantial link between price changes and trade volume.

2. Significance in the IMI calculation This indicator provides a more accurate representation of the market's momentum by including trading volumes in its IMI calculation. The IMI can filter any potentially misleading signals as a result of low trading activity or market anomalies by taking into account both price and volume data.

The following formula is used to calculate the IMI.

IMI = gains / gains + losses ✖ 100

Where gains are the sum of positive price changes multiplied by their respective trading volumes, losses are the sum of negative price changes multiplied by their respective trading volumes.

The process of calculating the Intraday Momentum Index

1. Identifying data inputs First, traders will need to obtain the data inputs that are required for IMI calculations, namely high, low, open, and closed prices and the trading volume of the security concerned.

2. Computing price differences By subtracting the open price from the high price and the low price from the open price, traders must calculate the price difference. For the calculation of the IMI, this step provides the necessary data on gains and losses.

3. Calculating IMI Values Finally, traders are required to calculate the IMI by dividing the amount of gains by the total of losses and multiplying the result by 100. The resulting values generally range from zero to 100, with higher values indicating stronger upward momentum and lower values suggesting downward momentum.

The strategies that use the intraday momentum index are as follows.

Trend Identification

1. Bullish and Bearish trends The IMI can assist traders in identifying bullish and bearish trends. If the IMI is above 50 and rising, it can be interpreted as a bullish signal, while an IMI below 50 and falling may constitute a bearish signal.

2. The strength and duration of trends Traders will be able to assess the strength and duration of identified trends by looking at the relative position and movement of the IMI. A strong and sustained trend can be confirmed by an increasing or declining IMI, in addition to its continuing presence in these areas.

Trade Entry and Exit signals

1. Crossover Method Using the IMI, crossovers are a popular trading approach. A cross below 30 may indicate a purchase indication, while a cross above 70 may indicate a sell signal.

2. Divergence Method Trading on differences between the IMI and price is another tactic. A buy signal may be given by the IMI increasing while the price is decreasing, while a sell signal may be given by the IMI declining while the price is rising.

The drawbacks of the intraday momentum index are mentioned below.

1. False sounds and signals The IMI may provide unreliable signals, particularly in tumultuous and sideways markets, as with any technical indicator. To improve its accuracy and reliability, the IMI should be used by traders in conjunction with other analysis tools and strategies.

2. The dependence on historical data Historical price and volume data are relied on a lot by the IMI. This data is potentially useful for understanding past market behaviour, and it may not always be accurate in predicting future trends.

3. The effects of market volatility and additional external factors Various outside factors, for example, market turbulence, news from the economy, and changes in investor sentiment can influence the IMI. These factors should be taken into account by market participants, and their strategies should be adapted accordingly.


Day traders use the intraday momentum trading tool as an excellent technical analysis indicator to measure momentum in a single trading day. It identifies possible entry points and exits in complex markets through a combination of price and volume data. Changes in prices, high and low prices, closing and open prices, as well as the volume of transactions, shall be considered by the IMI calculation. Traders interpret the IMI values as a signal of overbought and oversold levels, divergences and convergences, and trend identification.

FAQs on Intraday Momentum Index

Relative strength index, moving averages, stochastic oscillator, Bollinger bands, and volume are some of the best intraday indicators. In addition to the RSI and stochastic oscillators indicating overbought or oversold conditions, moving averages help traders identify trends and potential reversals.

Day traders should consider stocks that have ample liquidity, a moderate volatility range, and followers in the sector or index group. To identify the correct stocks for an intraday position, it is essential to isolate a current market trend from any other noise and take advantage of that trend.

To establish a clear and consistent intraday trading strategy that is suited to your appetite for risk, style of trade, and investment objectives. Rules on entry and exit points, stop losses, targets for profits, and risk management should be part of your strategy.

The price rate of change (ROC), stochastic oscillator, moving average convergence divergence (MACD), and relative strength index (RSI) are some of the primary techniques used to quantify momentum.

The True Strength Index (TSI), Rate of Change (ROC), Stochastic Oscillator, Moving Average Convergence Divergence (MACD), and Relative Strength Index (RSI) are examples of momentum indicators.
