Definition. The Money Flow Index (MFI) is a momentum indicator that uses both price and volume data to identify overbought or oversold conditions, ranging from 0% to 100%.

Technical. Calculated using a 14-day period, MFI incorporates typical price (average of high, low, and close) multiplied by volume to measure buying and selling pressure. The metric tracks MFI for spot trades where USD or USD-related currencies serve as the quote, and can be viewed per exchange or aggregated across exchanges.

Interpretation. Readings above 80% typically indicate overbought conditions and readings below 20% indicate oversold conditions.
