Money Flow Index

How to generate trading signals using Money Flow index and 100 DMA?


Price and volume are two of the most basic but very essential indicator in technical analysis to predict price movement. To take care of price and volume data, you may use Money Flow Index (MFI).

MFI is a momentum oscillator which identifies the momentum of outflow and inflow of money of a stock over a given time period. It is one of the popular technical tools found in most trading platform.

The Money Flow Index (MFI) calculation involves the following steps-

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

2. Raw Money Flow = Typical Price x Volume

3. Money Flow Ratio = (14-period Positive Money Flow) / (14-period Negative Money Flow)

4. Money Flow Index = 100 – {100 / (1 + Money Flow Ratio)}

MFI interpretation

MFI is also known as a volume-weighted version of RSI as it is interpreted similar to RSI oscillator; however the main difference in MFI is with regards to volume. Due to the volume feature, MFI works little differently than that of RSI.

By computing the indexed value depending on the number of bars (as specified in the money flow index setting), a line is plotted on the chart which oscillates between 0 and 100 level.

With the rise in stock price, the MFI also goes up which signals increasing buying pressure. On the other hand, MFI goes down with the decrease in price thus signalling decreasing buying pressure. Thus you may predict directional movement of market simply by keeping a watch on MFI.

Strategies using MFI

Case 1: When price cuts above 20 SMA from below and simultaneously MFI also cuts above the 40 line, it generates a buy signal.
