What is money flow index indicator?

Money flow index was created by gene Quong and Avrum Soudak. You will find the indicator in all trading platforms lượt thích the MT4 và our PPro8.

The MFI is a leading indicator that uses price and volume to lớn show whether the price is overbought or oversold. The index is usually positive when the price is rising và negative when the price is falling.

The best way lớn think of the MFI is lớn consider the RSI, which we covered before. Basically, Gene & Avrum understood the importance of volume và how it affects the markets. They therefore added volume khổng lồ the calculation of the MFI.

How khổng lồ Calculate: MFI formula

The MFI is calculated using a very simple formula. As we have written before, you don’t need to lớn know how these indicators are calculated.

While we have been in the trading business for many years and use these indicators often, we don’t know how most of them are calculated.

The MFI is calculated as follows:

You calculate the Typical Price (TP). You do this by adding the high, low, & close prices và then dividing the total by three.After finding the typical price, you calculate the Raw Money Flow. You vì this by multiplying the Typical Price with the volume.Calculate the Money Flow Ratio. You vì this by dividing the period (often 14) positive money flow by the period negative money flow.

Finally, the MFI is calculated by using the following formula.

Money Flow Index = 100 – 100 / (1 + Money Flow ratio)

A key difference between the RSI and the MFI is the default locations. In the RSI, the mặc định oversold màn chơi is 30 while the overbought is at 70. In the MFI, the two defaults are at 20 và 80, respectively.

However, you can always change these figures in the settings.

How to Use the money flow index

A good way lớn use the money flow index is to lớn identify the overbought and oversold levels. When the MFI is above 80, the price is said to be overbought. It is said to be oversold when it is below 20.

However, as we mentioned when talking about the RSI, it is not mandatory that a reversal will happen the overbought và oversold levels are reached.

The price may continue lớn move higher when it reaches the overbought level of 80. It may also continue khổng lồ move lower when it moves lớn below 20. This happens when there is a very strong trend.
