Forex Money Flow Index (MFI) Indicator

Forex Money Flow Index (MFI) Indicator is a momentum indicator that measures the flow of money into and out of a security over a specified period of time. It is related to the Relative Strength Index (RSI) but incorporates volume, whereas the RSI only considers price. The MFI is calculated by accumulating positive and negative Money Flow values (see Money Flow), then creating a Money Ratio. The Money Ratio is then normalized into the MFI oscillator form.

How this indicator works

Oversold levels typically occur below 20 and overbought levels typically occur above 80. These levels may change depending on market conditions. Level lines should cut across the highest peaks and the lowest troughs. Oversold/Overbought levels are generally not reason enough to buy/sell; and traders should consider additional technical analysis or research to confirm the security's turning point. Keep in mind, during strong trends, the MFI may remain overbought or oversold for extended periods.
If the underlying price makes a new high or low that isn't confirmed by the MFI, this divergence can signal a price reversal.
