Money Flow Index (MFI)

The Money Flow Index (MFI) is a technical oscillator that uses both price and volume data for identifying overbought or oversold signals in an asset.

* This chart uses synthetic data to demonstrate the indicator's behavior in typical market conditions.

Core Usage

Overbought above 80, Oversold below 20
Divergence analysis
Spotting price reversals

Advantages

  • Adds volume weighting that RSI does not use
  • Great for spotting exhaustion in a trend
  • Shows buying and selling pressure that price alone does not

Limitations

  • Can stay overextended in strong trends
  • Produces false signals in choppy markets
  • Volume data can be noisy or unreliable in some markets

Calculation Logic

Typical Price = (High + Low + Close)/3; Money Flow Ratio = (n-period Positive Money Flow) / (n-period Negative Money Flow); MFI = 100 - [100 / (1 + Money Flow Ratio)]

Understanding the mathematical logic behind indicators helps you interpret signals more accurately and avoid misuse in unsuitable market environments.
