Money Flow Index Calculator

The Money Flow Index (MFI) is a technical indicator used in technical analysis to identify overbought and oversold conditions in a market. It combines price and volume data to provide a more comprehensive view of market strength and weakness.

What is the Money Flow Index?

The Money Flow Index (MFI) is a momentum oscillator that measures the strength of buying and selling pressure over a specific period. It ranges from 0 to 100, where values above 80 indicate overbought conditions and values below 20 indicate oversold conditions.

The MFI is calculated using the following formula:

MFI = 100 - (100 / (1 + Money Flow Ratio)) Money Flow Ratio = (14-period Positive Money Flow) / (14-period Negative Money Flow)

The index is particularly useful for traders and investors looking to identify potential trend reversals or continuation. It's often used in conjunction with other technical indicators to confirm trading signals.

How to Use the Calculator

To use the Money Flow Index Calculator:

Enter the closing prices for each period in the "Closing Price" field
Enter the corresponding volumes for each period in the "Volume" field
Click the "Calculate" button to compute the MFI
Review the results and interpretation

The calculator will display the calculated MFI value along with an interpretation of what the value means in terms of market conditions.

Interpreting Results

The Money Flow Index provides several key insights:

Values above 80 suggest overbought conditions, indicating potential for a price decline
Values below 20 suggest oversold conditions, indicating potential for a price increase
Values between 20 and 80 indicate neutral conditions, with no strong buying or selling pressure

Traders often use the MFI in combination with other indicators to confirm trading signals. For example, a bullish crossover (when MFI moves from below 20 to above 20) might signal a potential buying opportunity.

Worked Example

Let's calculate the MFI for a simple example with 14 periods:

Period	Closing Price	Volume
1	$50.00	100,000
2	$52.00	120,000
3	$51.00	90,000
4	$53.00	110,000
5	$54.00	130,000
6	$55.00	140,000
7	$56.00	150,000
8	$57.00	160,000
9	$58.00	170,000
10	$59.00	180,000
11	$60.00	190,000
12	$61.00	200,000
13	$62.00	210,000
14	$63.00	220,000

Using the calculator with these values would produce an MFI of approximately 72, indicating strong buying pressure and potential overbought conditions.
