Using MFI, OBV, and Chaikin A/D to Read Trading Volume

Summary

The article explains how volume can add context to price action. It describes higher trading activity as often accompanying volatility and breakouts, and notes that historically busy price zones may act as areas of support or resistance. It presents three volume-based indicators: the Money Flow Index (MFI), On Balance Volume (OBV), and the Chaikin A/D Oscillator.

MFI combines price and volume in an oscillator used to assess overbought and oversold conditions. OBV cumulatively adds or subtracts volume according to whether the close rises or falls relative to the prior close; the article describes using a moving-average crossover for signals. The Chaikin oscillator compares short and longer exponential averages of the Accumulation/Distribution line, with zero-line crossings treated as directional signals. These are descriptions of indicator logic, not evidence of profitability. The article gives no tested results and does not establish that volume reliably predicts future prices; signals may need confirmation and can behave differently across assets and time frames.

Key ideas

• Volume measures trading activity and can provide context for price movements without acting as a standalone buy or sell signal.
• MFI combines price and volume to assess overbought and oversold conditions.
• OBV accumulates or subtracts volume based on the direction of the close.
• The Chaikin A/D Oscillator uses moving averages of the Accumulation/Distribution line, with zero crossings described as signals.
• The article offers indicator explanations but no empirical test of their performance.
