Brief Description
Chaikin Money Flow (CMF) is a volume-based technical indicator developed by Marc Chaikin to measure buying and selling pressure over a specified period. It combines price and volume to determine whether an asset is under accumulation (buying pressure) or distribution (selling pressure). CMF is built on the idea that strong buying tends to push prices toward the upper end of their daily range, while strong selling pushes prices toward the lower end.
The indicator oscillates around a zero line, with positive values indicating accumulation and negative values indicating distribution. CMF is typically calculated using a 21-period lookback.
Formula:
Chaikin Money Flow is calculated in three steps:
- Money Flow
Multiplier (MFM):
MFM = [(Close– Low) – (High – Close)] / High – Low
- Money Flow Volume (MFV):
MFV = MFM * Volume
- Chaikin Money Flow (CMF):
Uses:
1. Identifying Buying and Selling Pressure
The primary use of CMF is to assess accumulation and distribution:
- CMF above zero suggests buying pressure and accumulation.
- CMF below zero suggests selling pressure and distribution.
Sustained positive or negative readings can indicate the dominant market force.
2. Trend Confirmation
CMF can be used to confirm price trends. In an uptrend, CMF is expected to remain mostly above zero, making new higher highs and lows, confirming that volume supports rising prices. In a downtrend, readings below zero reinforce bearish conditions.
3. Divergence Analysis
Consequently, divergences between CMF and price can signal potential reversals:
- Bullish divergence: Price makes lower lows while CMF forms higher lows, indicating weakening selling pressure.
- Bearish divergence: Price makes higher highs while CMF forms lower highs, suggesting weakening buying pressure.
4. Filtering Trade Signals
CMF is often used as a filter alongside other indicators. For example, traders may only take long trades when CMF is positive and short trades when CMF is negative, improving signal quality. Alternatively, traders could use a rising CMF as a clue for a possible breakout towards the same direction, after a consolidation pattern.
Limitations:
01
Sensitivity to Gaps
Price gaps can distort the Money Flow Multiplier, leading to sudden shifts in CMF that may not accurately reflect ongoing market pressure. This purely due to the indicator’s formula. For example, a strong gap of a share’s price towards the upside, will not be reflected in the CMF value, because its formula doesn’t contain a reference to the price of the previous period. Therefore, it will only calculate its value based on the intra-period High, Low and Close.
02
Short - Term Noise
CMF can fluctuate frequently around the zero line, especially in sideways markets, producing whipsaws and unclear signals. A moving average could be used to dampen these swings.
03
Dependence on Volume Quality
As a volume-based indicator, CMF relies on accurate volume data. In markets where volume is unreliable and in thinly traded instruments, its effectiveness is reduced.
04
A Tool in the Toolbox
CMF does not provide precise entry or exit points on its own. It works best when combined with price action analysis, trend indicators, or support and resistance levels.
