Chaikin Money Flow (CMF)

Chaikin Money Flow (CMF) was developed by Marc Chaikin and combines price and volume data to produce an oscillator that measures the balance between buying and selling pressure over a rolling period — typically 20 or 21 periods. The indicator oscillates between -1 and +1, with values above zero indicating that money is flowing into the asset (buying pressure dominant) and values below zero indicating money is flowing out (selling pressure dominant). The CMF is calculated in two stages. First, a Money Flow Multiplier is derived for each period using the closing price's position within the high-low range — a close near the high produces a positive multiplier, a close near the low produces a negative one. This multiplier is then applied to the period's volume to produce the Money Flow Volume. The CMF is the sum of all Money Flow Volumes over the period divided by the total volume, normalising the result between -1 and +1. What makes CMF particularly useful for day traders is its volume integration. While price-only indicators can show a move without revealing whether genuine participation supports it, the CMF reveals whether volume confirms the price direction. A price rally accompanied by a rising CMF above zero signals institutional buying participation — a genuinely supported move. A price rally with CMF negative or declining signals weak participation — a potentially unsustainable move that may reverse. In the Intraday Session Framework, CMF serves as the volume confirmation layer in the three-tool confirmation architecture: SuperTrend provides trend direction, the Hull Moving Average confirms momentum, and CMF validates that volume is supporting the move. Entries taken when all three align carry significantly stronger structural justification than those relying on price action or trend indicators alone. Strong CMF readings — above 0.25 for bullish or below -0.25 for bearish — indicate meaningful buying or selling dominance and represent the most reliable confirmation signals. Signal Thresholds — Chaikin Money Flow (CMF) Standard period 21 (Chaikin's original). 20 is also widely used. Bullish zone CMF above 0: buying pressure is dominant. Sustained readings above 0 in an uptrend confirm accumulation. Bullish threshold CMF above +0.25: strong, consistent buying pressure. Institutional accumulation signal when price is consolidating. Bearish zone CMF below 0: selling pressure is dominant. Bearish threshold CMF below -0.25: strong distribution pressure. Sustained negative CMF during a price rally is a significant bearish divergence. Divergence Rising price with falling CMF (especially below 0): distribution (smart money selling into retail buying). Falling price with rising CMF (especially above 0): accumulation (smart money buying into retail fear).
