Chaikin Money Flow (CMF)
Chaikin Money Flow (CMF) measures buying versus selling pressure over a period by combining where each bar closes within its range with its volume. This article explains the money-flow multiplier, why a close near the high signals accumulation and near the low distribution, how CMF oscillates around zero (above = buying pressure, below = selling), how it differs from OBV, and how to read zero-line crosses and divergence.

On-Balance Volume (OBV)
On-Balance Volume (OBV) is a cumulative running total of volume that adds volume on up-close days and subtracts it on down-close days, turning volume into a single trend line. This article explains how OBV is built, why its direction (not its absolute value) is what matters, how a rising OBV confirms accumulation and a falling OBV distribution, how OBV divergence warns that a price move lacks volume support, and the idea that volume can lead price.
Money Flow Index (MFI)
The Money Flow Index (MFI) is often called a volume-weighted RSI: a 0-100 oscillator that folds volume into a momentum reading. This article explains how MFI uses the typical price and volume to measure money flowing in versus out, the 80/20 overbought/oversold zones, how it differs from RSI (volume) and from Chaikin Money Flow (construction), divergence, and the same trend caveat that extremes can persist.
