Money Flow Index is a similar indicator to the Relative Strength Index, however, the Money Flow Index uses volume to measure the strength of the money flowing in and out of the security.


The calculation is done in the following steps.

  1. For each bar, average the High, Low, and Close.

  2. The MF value is equal to the Average x Volume.

  3. If the value in step 1 is higher than the previous, it is considered to be a positive money value, otherwise negative. The positive money flow is then the sum of all the positive money values over the number of bars.

  4. The money ratio is then + MF divided by -MF.

  5. The Index is then 100 - (100 / (1 + Money Ratio)).
