Money Flow Index (MFI)
Also called: MFI, volume-weighted RSI
A 0–100 oscillator like RSI but weighted by volume — it gauges buying vs selling pressure, with above 80 overbought and below 20 oversold.
MFI is often called a volume-weighted RSI. It uses the typical price (high + low + close ÷ 3) and the day's volume to measure positive vs negative money flow over a lookback (commonly 14). Because it factors in volume, it can flag pressure that price-only oscillators miss.
Readings above 80 are overbought and below 20 oversold; divergence between MFI and price is a popular warning that a move lacks the volume to continue. As with RSI, extremes can persist in strong trends.
On StockSetups
MFI (14) is a screener field on StockSetups, so you can combine a money-flow read with the chart pattern — for example, requiring MFI to confirm rather than diverge as a name breaks out.
