Money Flow Index (MFI)

November 21, 2023 - Around 4 mins mins to read

The Money Flow Index (MFI) is a popular technical indicator used in financial markets to measure buying and selling momentum of a financial asset. Developed by Avrum Soudack and Gene Quong, the MFI takes into account both volume and price action to provide insights into market trends and potential reversals.

The MFI calculates the money flow ratio, also known as the money ratio, by summing positive and negative money flows. A rise in the price of an asset indicates positive money flow, indicating purchasing pressure, while a fall in price implies negative money flow, indicating selling pressure. The money ratio is then used to calculate the MFI, which ranges from 0 to 100.

By combining volume and price data, the MFI helps traders identify price extremes and potential reversals. For example, a reading above 80 is considered overbought and suggests a price reversal to the downside may occur. Conversely, a reading below 20 indicates oversold conditions and may signal a price reversal to the upside.

Let’s look at an example to better understand the MFI. Consider Bitcoin (BTC) when it was trading around $40,000. At that time, the MFI indicator had a reading of 20, indicating that BTC was oversold both in terms of price and volume. After that, BTC experienced a significant price increase, reaching an overbought position on the daily chart with an MFI reading above 80. This example demonstrates how the MFI can provide valuable insights into market conditions and help traders make informed decisions.

What is the purpose of using the Money Flow Index (MFI)?

The Money Flow Index is widely used by traders and analysts to identify potential divergences in price trends. When the MFI oscillator moves in the opposite direction of price, it is known as a divergence. This divergence suggests a potential reversal in the current price trend, providing traders with an opportunity to take advantage of the upcoming market movement.

While the MFI and the Relative Strength Index (RSI) are similar indicators, the key distinction is that the MFI takes volume into account, unlike the RSI. This makes the MFI a preferred choice for many traders and analysts, as it offers more timely indications and warnings of potential reversals.

What is the best setting for the Money Flow Index (MFI)?

The optimal settings for the Money Flow Index (MFI) may vary depending on individual trading strategies and preferences. However, a commonly used and recommended setting is as follows:

  • Overbought signal line: 80
  • Oversold signal line: 20

The overbought signal line at 80 indicates that an asset may be overvalued and a price reversal to the downside could occur. Conversely, the oversold signal line at 20 suggests that an asset may be undervalued and a price reversal to the upside could occur.

What is the Money Flow Index (MFI) Formula?

To calculate the Money Flow Index (MFI), the following formula is used:

Money Flow Ratio = 14 Period Negative Money Flow / 14 Period Positive Money Flow

Raw Money Flow = Typical Price x Volume

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

The MFI formula involves the calculation of the money flow ratio, which compares the inflows and outflows of money over a specified period. The raw money flow is then computed by multiplying the typical price (average of high, low, and close) by the volume traded. Finally, the MFI is derived by applying the formula to the money flow ratios.

While the Money Flow Index is a reliable indicator, it should not be relied upon solely for making trading decisions. It is recommended to use the MFI in conjunction with other technical indicators such as the Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), On-Balance Volume (OBV), Aroon Indicator, and stochastic oscillator to gain a comprehensive understanding of market conditions before entering or exiting a trade.
