What is Money Flow Index?


Regularly monitoring the price of stocks or commodities requires a lot of time. You might have to examine price movement for over a hundred different companies in various global businesses as part of your daily trading routine. Economists have created several practical tools to make this process easier for you daily.

Understanding Money Flow Index

Technical analysts utilise the Money Flow Index (MFI), a movement indicator that looks at price and time to gauge the pressure on a trader to purchase or sell. Because it takes volume into account in addition to price, as opposed to only price, it is also known as the volume-weighted Relative Strength Index (RSI).

An increase in the usual price signals positive money flow and purchasing pressure, whereas a decline in the typical price signals negative money flow and selling pressure. These positive and negative money flows are added to create a money flow ratio, sometimes referred to as a money ratio.

The MFI that varies between 0 and 100 is determined using the money ratio. The MFI may be used to identify price extremes and reversals with various signals since it takes volume into account.


The Formula for the Money Flow Index (MFI)

Money Flow (MF): Determine the Money Flow (MF) for every day in the chosen time frame. The money flow is calculated by taking the volume of shares traded on a given day and multiplying it by the average price of the day.

Money Flow = Typical Price * Volume

Typical Price = (High + Low + Close) / 3

Positive Money Flow (PMF) and Negative Money Flow (NMF): The total money flow on days with higher or lower usual prices is measured using the concepts of Positive Money Flow (PMF) and Negative Money Flow (NMF), respectively.

Money Ratio (MR): Calculate the Money Ratio, which is the ratio of the average of the Positive Money Flow to the average of the Negative Money Flow over the specified period.

Money Ratio = PMF / NMF

Money Flow Index (MFI): Finally, compute the Money Flow Index using the Money Ratio calculated in the previous step.

MFI = 100 - (100 / (1 + Money Ratio))

How to Calculate the Money Flow Index?

Establishing the normal price of a stock is the first step in calculating the money flow index. You may get the usual price of a stock by averaging its closing price, high price, and low price.

  • Determine the average price for the last 14 periods.
  • Indicates if the average price for each period was more or lower than the previous one. This will indicate if there is a positive or negative raw money flow.
  • Multiply the average price by the volume for that time to determine the raw money flow. Use negative or positive values depending on whether the period was up or down (see step above).
  • By summing together all of the positive money flows during the previous 14 periods and dividing them by the negative money flows simultaneously, you can find the money flow ratio.
  • Utilising the ratio discovered in step four, compute the Money Flow Index (MFI).
  • Using just the data from the previous 14 times, calculate when each new period will close.

Difference Between the Money Flow Index and Relative Strength Index (RSI) 

The RSI and MFI have a tight relationship. The primary distinction is that RSI does not consider volume, but MFI does. Volume analysis proponents think it's a leading sign. As a result, MFI will issue signals and alert investors to potential reversals earlier than RSI. Neither indication is superior to the other; they are just using different components, which will cause them to produce signals at various times.

Advantages of Calculating the Money Flow Index

Some of the advantages of using the Money Flow Index (MFI) are as follows:

  1. Overbought & Oversold Identification: MFI values above 80 suggest that the market may be overbought and point to a likely downward correction. On the other hand, readings less than 20 indicate that the market is oversold and may be about to rise in price. Early detection of these extremes aids in forecasting market movements and enables traders to make wise choices.
  2. Divergence Indication: MFI movements sometimes oppose stock price trends, offering insights.
  3. Bullish Divergence: If the stock is still falling and the MFI is extremely low (below 20), this might indicate that selling pressure is lessening. This may signal a spike in interest in purchasing, offering a chance to purchase equities at competitive prices.
  4. Bearish Divergence: When stock prices rise and the MFI is high (over 80), it may be a sign of increasing selling pressure. This points to a probable seller inflow soon, enabling traders to sell equities at higher prices.
  5. Failure Swing Detection: This advanced divergence pattern signifies potential price reversals.
  6. Bullish Failure Swing: When stock prices reach a lower low, but the MFI surpasses the previous high, it triggers a buy signal, indicating a potential price reversal.
  7. Bearish Failure Swing: If stock prices achieve a higher high, but the MFI falls below the prior low, it triggers a sell signal, hinting at a possible impending price decline.

Limitations of the Money Flow Index

Beyond market data predictions, many more variables influence a stock's price. A natural disaster or an unexpected scarcity of semiconductors affects a company's infrastructure. The market is impacted by these exact causes as the underlying stocks. Therefore, forecasting for the following two weeks may not be possible using the market divergence data based on the prior two weeks. 

When making financial decisions, it's essential to use care and not depend only on one indicator, even if the Money Flow Index (MFI) provides insightful information about market dynamics and possible price fluctuations. A more thorough grasp of market circumstances may be obtained by combining the MFI with additional technical analysis tools and fundamental research.The financial markets are complex and subject to several influences. In trading or investing, no one sign can ensure success. Therefore, making educated and wise financial decisions with your assets requires combining various analysis techniques, taking risk management tactics into account, and keeping up with general market trends.

What is Money Flow Index?

It is a sell signal if the Money Flow Index indicator displays an overbought state. An indication to purchase is an oversold situation.

Yes, because MFI is volume-based, it can be considered a leading indicator.

A technical indicator called the Money Flow Index shows if a particular asset is overbought or oversold. Overbought security is indicated by a value above 80, while oversold security is indicated by a value below 20.

Generally, a bullish market is indicated over 50 by the money flow index, while a bearish market is indicated by below 50.

Understanding market dynamics and price reversals is possible with the help of the MFI. When the MFI and stock price movements diverge, it may be used by traders to identify possible changes in buying or selling pressure.
