Introduction
Developed by Marc Chaikin, Chaikin Money Flow measures the amount of Money Flow
Volume over a specific period. Money Flow Volume forms the basis for the Accumulation
Distribution Line. Instead of a cumulative total of Money Flow Volume, Chaikin Money Flow
simply sums Money Flow Volume for a specific look-back period, typically 20 or 21 days.
The resulting indicator fluctuates above/below the zero line just like an oscillator. Chartists
weigh the balance of buying or selling pressure with the absolute level of Chaikin Money
Flow. Chartists can also look for crosses above or below the zero line to identify changes
on money flow.
Calculation
There are four steps to calculating Chaikin Money Flow (CMF). The example below is based
on 20-periods. First, calculate the Money Flow Multiplier for each period. Second, multiply
this value by the period's volume to find Money Flow Volume. Third, sum Money Flow
Volume for the 20 periods and divide by the 20-period sum of volume.
2. Money Flow Volume = Money Flow Multiplier x Volume for the Period
3. 20-period CMF = 20-period Sum of Money Flow Volume / 20 period Sum of Volume
Each period's Money Flow Volume depends on the Money Flow Multiplier. This multiplier is
positive when the close is in the upper a half of the period's high-low range and negative
when the close is in the lower half. The multiplier equals 1 when the close equals the high
and -1 when the close equals the low. In this way, the multiplier adjusts the amount of
volume that ends up in Money Flow Volume. Volume is in effect reduced unless the Money
Flow Multiplier is at its extremes (+1 or -1).

The table above shows some examples using daily data for Research in Motion (RIMM).
Notice how the multiplier was near +1 on 5-Jan when the stock closed near its high. The
multiplier dipped to -.97 on 18-Jan when the stock closed near its low. The multiplier
finished near zero (-.07) when the stock closed near the midpoint of its high-low range on
29-Dec. Click here for a calculation example of Chaikin Money Flow in an Excel

Interpretation
Chaikin Money Flow (CMF) is an oscillator that fluctuates between -1 and +1. Rarely, if ever,
will the indicator reach these extremes. It would take 20 consecutive closes on the high
(low) for 20-day Chaikin Money Flow to reach +1 (-1). Typically, this oscillator fluctuates
between -0.50 and +0.50 with zero as the centerline.

Chaikin Money Flow measures buying and selling pressure for a given period of time. A
move into positive territory indicates buying pressure, while a move into negative territory
indicates selling pressure. Chartists can use the absolute value of Chaikin Money Flow to
confirm or question the price action of the underlying. Positive CMF would confirm an
uptrend, but negative CMF would call into question the strength behind an uptrend. The
reverse holds true for downtrends.
Buying/Selling Pressure
Chaikin Money Flow can be used to define a general buying or selling bias simply with
positive or negative values. The indicator oscillates above/below the zero line. Generally,
buying pressure is stronger when the indicator is positive and selling pressure is stronger
when the indicator is negative.
While this zero line cross seems simple enough, the reality is much choppier. Chaikin
Money Flow sometimes only briefly crosses the zero line with a move that turns the
indicator barely positive or negative. There is no follow through and this zero line cross
ends up becoming a whipsaw (bad signal). Chartists can filter these signals with buffers by
3/11
setting the bullish threshold a little above zero (+0.05) and the bearish threshold a little
below zero (-0.05). These thresholds will not entirely eliminate bad signals, but can help
reduce whipsaws and filter out weaker signals.
The chart above shows Freeport McMoran (FCX) with 20-day Chaikin Money Flow in the
indicator window. There were at least 10 crosses of the zero line between February and
December 2010. Adding a small buffer greatly reduced the number of bullish and bearish
signals. A move above +0.05 was considered bullish, while a move below -0.05 was
considered bearish. There were only three signals. While these signals will come a little
later, it may be worth it to reduce whipsaw.

The chart for Harley Davidson (HOG) shows a few good signals and a whipsaw with the
May bounce. CMF moved above +0.05 for a few days, but this move failed to hold and the
indicator broke back below -0.05 in early June. Whipsaws are going to happen, especially
during volatile periods or when the trend flattens. CMF turned bullish in July and stayed
bullish the rest of the year. Notice that HOG formed a falling wedge that retraced just over
62% in August, when CMF was still in bull mode. This pullback offered a second chance to
partake in the CMF signal.
5/11
Chaikin Money Flow is not suited for all securities. The chart above shows P.F. Chang
(PFCB) with some 18 crosses above +0.05 or below -0.05. Basing CMF signals on these
crosses resulted in one whipsaw after another. It is important to analyze the basic price
trend and the characteristics of an indicator with a particular security. PFCB exhibits some
trend, but price action within this trend is choppy and money flow cannot maintain a
positive or negative bias. It would be better to find a different indicator for this stocks.
Calculation Quirk
The Money Flow Multiplier in Chaikin Money Flow focuses on the level of the close relative
to the high-low range for a given period (day, week, month). With this formula, a security
could gap down and close significantly lower, but the Money Flow Multiplier would rise if
the close were above the midpoint of the high-low range. The chart below shows Clorox
(CLX) with a big gap down and a close near the top of the day's high-low range. Even
though the stock closed sharply lower on high volume, Chaikin Money Flow rose because
the Money Flow Multiplier was positive and volume was well above average. Ignoring the
change from close-to-close means that Chaikin Money Flow can sometimes disconnect
with price.
6/11
The opposite can happen when a security gaps up and closes near the low for the day. The
chart below shows Travellers (TRV) gapping up and closing over 1% higher on the day.
Despite this jump, the close was near the low for the day, which insured a Money Flow
Multiplier near -1. As a result, almost all of the day's volume was counted as negative
money flow and the Chaikin Money Flow fell.

Conclusions
Chaikin Money Flow is an oscillator that measures buying and selling pressure over a set
period of time. At its most basic, money flow favors the bulls when CMF is positive and the
bears when negative. Chartists looking for quicker money flow shifts can look for bullish
and bearish divergences. Be careful though. Selling pressure still has the edge in negative
territory, even when there is a bullish divergence. This bullish divergence simply shows less
selling pressure. It takes a move into positive territory to indicate actual buying pressure.
As a money flow oscillator, CMF can be used in conjunction with pure price oscillators,
such as MACD or RSI. As with all indicators, Chaikin Money Flow should not be used as a
stand-alone indicator. Marc Chaikin also developed the Accumulation Distribution Line and
the Chaikin Oscillator.

Note: For the purposes of scanning, daily volume data is incomplete during the trading day.
When running scans with volume-based indicators like CMF, be sure to base the scan on
the “Last Market Close.” Examples of other volume-based indicators include
