GMMA: Guppy Multiple Moving Average

GMMA: Graphical representation of GMMA analysis.

In financial trading, the Guppy Multiple Moving Average (GMMA) stands out as a powerful tool designed to reveal the underlying trend strength and potential changes in market sentiment. Developed by Daryl Guppy, an Australian financial analyst, the GMMA utilizes a set of exponential moving averages (EMAs) to provide a comprehensive view of both short-term traders behavior and long-term investors' sentiment. 

This innovative approach, allows traders to simultaneously capture the sentiment of short-term traders and the conviction of long-term investors, providing a comprehensive picture of market dynamics. This article explores the intricacies of GMMA, its calculation, its application in trading strategies and how it compares to traditional EMA indicators.

What is GMMA?

The GMMA is a technical analysis tool consisting of two sets of exponential moving averages (EMAs): one set identifies short-term trading sentiment, and the other reflects the consensus among long-term investors. By analyzing the interaction between these two groups of EMAs, traders can discern potential trend changes and strength, making it an invaluable tool for decision-making in fast-moving markets.

At its core, the GMMA is an ensemble of 12 EMAs that are grouped into two categories: a short-term group that reflects the immediate sentiment of traders and a long-term group that indicates the prevailing trend as seen by investors. This dual perspective helps traders identify potential trend changes and confirm the strength of existing trends, making it an essential tool for strategic decision-making.

GMMA formula and calculation

The GMMA utilizes two sets of EMAs:

  • Short-term group: 3, 5, 8, 10, 12, and 15 periods
  • Long-term group: 30, 35, 40, 45, 50, and 60 periods

Each EMA within the GMMA is calculated using the standard formula, which assigns greater importance to the most recent data, enhancing its responsiveness to market changes.


Consider a stock with the following closing prices over 10 days: $50, $51, $52, $53, $54, $55, $54, $53, $52, and $51. 

To calculate a 3-period EMA (one of the short-term EMAs in the GMMA), you would apply the EMA formula, focusing on the most recent three days. This simplified example illustrates the process of calculating one EMA within the GMMA framework.

The calculation for each EMA within the GMMA follows the standard EMA formula, which applies weighting to the most recent data points, making it more responsive to new information.

How to trade with the GMMA

Trading with the GMMA involves observing the separation and convergence of the short-term and long-term EMA groups. A widening gap suggests a strengthening trend, while a narrowing gap indicates a weakening trend or potential reversal. Traders often look for crossovers between the two groups as signals for entry or exit points.


Imagine a scenario where the short-term EMAs start to diverge upwards from the long-term EMAs in the GMMA on a stock's chart. This divergence suggests increasing bullish sentiment among short-term traders. A trader might view this as a buying opportunity, anticipating that the long-term EMAs will eventually follow if the trend continues. 

Conversely, if the short-term EMAs converge and cross below the long-term EMAs, it might signal a selling point, indicating a shift toward a bearish trend.

GMMA vs. an EMA

While the GMMA and EMA are based on the same exponential calculation, the GMMA offers a more nuanced view by incorporating multiple EMAs. This layered approach allows traders to simultaneously gauge market sentiment across different time frames, providing a deeper insight into trend strength and potential reversals than a single EMA line can offer.

While a single EMA might indicate a trend's direction, the GMMA's array of EMAs offers insights into the trend's strength, sustainability, and potential points of reversal through the interaction between its short-term and long-term components.


The Guppy Multiple Moving Average (GMMA) is a sophisticated tool that enables traders to analyze market trends through the lens of both short-term traders and long-term investors. Its comprehensive approach to trend analysis makes it superior to the singular perspective provided by a traditional EMA. 

By mastering the GMMA, traders can enhance their ability to make informed decisions, capitalizing on market movements more effectively. In summary, it can:

  • GMMA offers a nuanced view of market trends by combining short-term and long-term EMAs.
  • It helps traders identify trend changes and confirm trend strength by analyzing the interaction between two EMA groups.
  • Examples of GMMA application in trading include identifying divergences for buy/sell signals and comparing its insights with single EMA indicators for a more comprehensive analysis.
