What is Money Flow Index?

The Money Flow Index (MFI) is a technical indicator that measures the flow of money into and out of a security over a specified period. It is similar to the Relative Strength Index (RSI).  However, MFI incorporates trading volume, whereas RSI considers only price. 

Positive money flow occurs when the typical price increases, indicating buying pressure. Whereas a decrease in the typical price reflects negative money flow, signalling selling pressure. Positive and negative money flows are combined to calculate the money flow ratio, which is used to derive the MFI.  The MFI ranges from 0 to 100 and helps identify overbought, oversold, and potential reversal points by considering both price and volume. This article explains what is money flow index indicator in detail. 

Importance of Money Flow Index (MFI) 

The key importance of the MFI is as follows: 

1. Confirms Price Movements with Volume: The MFI incorporates trading volume, which helps validate price movements. Rising prices supported by high volume indicate strong buying pressure, while price increases on low volume may signal a weak or unsustainable rally. 
2. Identifies Overbought and Oversold Conditions: The MFI ranges between 0 and 100 and is used to spot extreme market conditions. Readings above 80 suggest overbought levels, while readings below 20 indicate oversold levels. 
3. Provides Early Reversal Signals: It can indicate a possible trend reversal when price and MFI move in opposite directions. Bearish indications indicate weakening buying pressure, and bullish indications indicate weakening selling pressure. 
4. Helps Assess Trend Strength: The 50 level on the MFI acts as a reference point for trend direction. An MFI consistently above 50 signals dominant buying pressure, while an MFI consistently below 50 reflects dominant selling pressure. 

The Formula for the Money Flow Index (MFI) 

Here’s the formula for the money flow index calculation:   

Step 1: Calculate the Typical Price 

This represents the average price movement for the day. 

Formula: Typical Price = (High + Low + Close) ÷ 3 

Step 2: Determine Positive or Negative Money Flow 

If today’s Typical Price is higher than yesterday’s, it is considered Positive Money Flow. 

If today’s Typical Price is lower than yesterday’s, it is considered Negative Money Flow. 

Step 3: Calculate Raw Money Flow 

Raw Money Flow is calculated by multiplying the Typical Price by the trading volume. 

Formula: Raw Money Flow = Typical Price × Volume 

This calculation is repeated for each of the past 14 periods. 

Step 4: Calculate Money Ratio 

Add all Positive Money Flows (PMF) over 14 periods and divide by the sum of Negative Money Flows (NMF). 

Formula: Money Ratio = 14-period PMF ÷ 14-period NMF 

Step 5: Use the MFI Formula 

Now, substitute the Money Ratio into the following formula: 

MFI Formula: MFI = 100 − [100 ÷ (1 + Money Ratio)] 

Interpreting MFI 

• Above 70: Overbought zone 
• Below 30: Oversold zone 

These levels can be adjusted based on the asset’s behaviour or overall market volatility. 

How to Calculate the Money Flow Index? 

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

• Step 1: Determine the average price for the last 14 periods. 
• Step 2 : 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. 
• Step: 3 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). 
• Step 4: Money flow ratio can be calculated by summing together all of the positive money flows during the previous 14 periods and dividing them by the negative money flows simultaneously. 
• Step 5: Utilising the ratio discovered in step four, compute the Money Flow Index (MFI). 
• Step 6: 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 MFI and RSI differ in the following ways: 

 Advantages and Disadvantages of the Money Flow Index 

MFI has the following advantages and disadvantages:

Conclusion  

When making financial decisions, it's essential not to 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 inancial decisions with your assets requires combining various analysis techniques, taking risk management tactics into account, and keeping up with general market trends.
