The Money Flow Index is a rather unique indicator that combines momentum and volume with an RSI formula. RSI momentum generally favors the bulls when the indicator is above 50 and the bears when below 50. Even though MFI is considered a volume-weighted RSI, using the centerline to determine a bullish or bearish bias does not work as well. Instead, MFI is better suited to identify potential reversals with overbought/oversold levels, bullish/bearish divergences and bullish/bearish failure swings. As with all indicators, MFI should not be used by itself. A pure momentum oscillator, such as RSI, or pattern analysis can be combined with MFI to increase signal robustness.
