Among numerous, the Money Flow Index (MFI) is an important tool in trading that helps traders and investors understand market trends and momentum in a detailed way. 

Created by Gene Quong and Avrum Soudack, MFI combines information about the price and volume of trades. This index doesn’t just show how strong a trend is and reveals when a trend might change direction. 

By looking at how money moves in and out of a stock, traders can make smart choices and determine if a stock is being bought too much (overbought) or sold too much (oversold).

In this blog, let’s discuss the meaning of MFI, its importance, and how it works.

What is the Meaning of the Money Flow Index?


The Money Flow Index (MFI) is a tool traders and investors use to understand the strength and potential changes in the price of a stock. It tells you whether money flows into or out of a particular investment. 

This indicator looks at both the volume of trades and the price movements to determine if buyers or sellers control the market. By keeping an eye on the money flow, traders can get insights into market sentiment and potential shifts in trends.

The MFI works by – 

  • Comparing positive and negative money flows over a specific time period. Positive money flow indicates buying pressure, while negative money flow shows selling pressure. 
  • It uses the average of high, low, and closing prices (called the typical price) and the volume traded during that time to calculate these flows. The result is a positive-to-negative money flow ratio, which is then scaled from 0 to 100 to give the MFI.

What are the Uses of the Money Flow Index Indicator?

People mainly use the Money Flow Index to find signs suggesting the price might be about to change direction. The Money Flow Index indicator is useful in technical analysis for these top five purposes.

  • Confirming Price Trends

The MFI helps us see how strong and lasting price trends are. When the MFI goes along with the current price trend, it shows the market is strong and doing well. However, if there are differences between the MFI and the price movement, it could be a sign that the trend might change soon.

  • Spotting Potential Trend Reversals

The MFI helps traders find possible changes in the direction of a trend by looking at how much people are buying and selling. Differences in these actions can indicate early signs that the market mood might change, and there could be upcoming shifts in trends.

  • Filtering Trade Signals

The MFI works as a filter for trade signals from other indicators. Traders use it to decide whether to start a trade or change their risk Money Flow Index Strategy.

If a trading method says “buy,” but the MFI says the market is too busy, traders might be cautious.

On the other hand, if the MFI is low when there’s a “sell” signal, it could be a sign that the market is oversold, giving a warning to traders.

  • Assessing Market Strength

The MFI helps us see how much people buy and sell in the market. If the MFI is low, it means a lot of selling is going on. But if the MFI is high, it shows that a lot of buying is happening. 

So, by watching the MFI, traders can determine whether a stock or the market is strong or weak.

  • Comparing Securities

How To Buy Using The Money Flow Index (MFI) Indicator?

Using the Money Flow Index (MFI) indicator to buy involves looking at its readings to find good times to make trades. Follow the steps mentioned below when using the MFI indicator to buy –

  1. Spot Oversold Conditions – Watch for MFI readings below 20, which means things have been oversold. This might be a chance to buy because there’s been a lot of selling, which could become an opportunity.
  2. Check for Bullish Divergence – Look for a bullish divergence, where the price chart goes lower, but the MFI indicator increases. This could suggest a buying chance because selling pressure might be going down, and a change in the trend might be coming.
  3. Confirm with Price Movement – Before making a trade based on MFI, ensure the price movement supports it. Look for signs like bullish candlestick formations, trendline breaks, or the price bouncing off important support levels. These things make it more likely that buying is a good idea.
  4. Wait for Other Signals – Besides oversold conditions and bullish divergence, wait for other signals indicating a change in the trend. This could be a shift in overall market sentiment, positive news, or other technical indicators supporting an upward move.
  5. Check Volume Confirmation – Confirm buying signals with volume data on the MFI. If there’s an increase in buying volume during oversold conditions, it suggests more traders and investors are interested in buying.
  6. Set Entry and Exit Points – After finding a buying chance, decide when to enter the trade and set a stop-loss order to manage risk. Place the entry point just above the confirmation level and the stop-loss order below the recent low point. Also, set a profit target based on your risk-reward ratio.
  7. Monitor and Adjust – Keep an eye on the MFI indicator and price movement after making the trade. Adjust your stop-loss order or take profits as the price moves in your favor. Stay flexible and adapt as needed.

How To Sell Using The Money Flow Index (MFI) Indicator?

When you sell using the Money Flow Index indicator, you use MFI readings to find good times to sell or exit your trades. Follow these steps when selling with the Money Flow Index indicator – 

  1. Monitor Overbought Conditions – Things might be too expensive if the MFI is higher than 80. Keep an eye on it because the market or the thing you invested in might need to correct its price or change direction. If the MFI goes past 80, it’s a sign that you should consider selling your investments or taking your profits.
  2. Watch for Bearish Divergences – Keep an eye out for “bearish divergences” between the MFI and the price of a stock. If the price keeps increasing, but the MFI starts decreasing, that’s a bearish divergence. It’s a signal that the trend might change, and it could be a good time to sell or consider getting out of any long-term investments you have.
  3. Identify Reversal Patterns – Use the Money Flow Index indicator along with other tools to spot likely trend reversals. If you notice a bearish reversal pattern, such as a double top or a bearish engulfing candlestick pattern, it strengthens the sell signal when the MFI shows overbought conditions (above 80). 
  4. Set Price Targets – Decide how much you want to sell your asset by looking at the MFI numbers and other important things. If the MFI shows that things are too expensive or not looking good, set goals to make a profit or stop selling if you’re making money. Adjust how you sell depending on how strong the MFI numbers are and the overall market. 
  5. Take Volume Confirmation into Account – The MFI looks at how much trading is happening and helps find signs that people might be selling stocks. If you see a lot of selling and the MFI is high or showing a negative trend, it’s a good reason to consider selling your stocks.
  6. Combine with Other Indicators – It’s often helpful to use the Money Flow Index indicator along with other tools when making decisions. Look at things like trendlines, moving averages, or support and resistance levels to confirm the signals the MFI gives you to sell.
