Direct Answer

The Guppy Multiple Moving Average (GMMA) is a trend indicator developed by Daryl Guppy that plots two groups of exponential moving averages together: a short-term group (commonly 3, 5, 8, 10, 12, and 15 periods) and a long-term group (commonly 30, 35, 40, 45, 50, and 60 periods). When both groups are tightly bunched, it suggests consensus or consolidation; when the short-term group separates and moves decisively away from the long-term group, it's read as a strengthening trend.

Key Takeaways

  • GMMA plots two EMA groups at once, a short-term group and a long-term group, rather than a single moving-average pair.
  • The short-term group commonly uses EMA periods of 3, 5, 8, 10, 12, and 15; the long-term group commonly uses 30, 35, 40, 45, 50, and 60.
  • Tight bunching within or between the groups is commonly read as consensus/consolidation; decisive separation between the groups is read as a strengthening trend.
  • Every line is an exponential moving average of past prices, so GMMA is a lagging indicator that confirms a shift in the balance between short-term and long-term participants rather than predicting one.

What Is the Guppy Multiple Moving Average?

The Guppy Multiple Moving Average (GMMA) is a trend indicator developed by Daryl Guppy. Instead of plotting one or two moving averages, GMMA plots twelve exponential moving averages (EMAs) at once, split into two groups of six. The idea behind grouping them this way is to approximate two different populations of market participants: a short-term group, meant to reflect traders operating on shorter time horizons, and a long-term group, meant to reflect longer-horizon investors.

Because each group is made up of several EMAs of different lengths rather than a single line, the width and behavior of each group carries information on its own. A group of EMAs that are close together and moving in parallel suggests the participants that group represents are in broad agreement about price. A group that is fanning apart suggests growing disagreement within that same population. Comparing the two groups' position and spacing relative to each other is the core of how GMMA is read.

The Formula

Short-term group = EMA(3), EMA(5), EMA(8), EMA(10), EMA(12), EMA(15) of price, plotted together.

Long-term group = EMA(30), EMA(35), EMA(40), EMA(45), EMA(50), EMA(60) of price, plotted together.

GMMA is built directly on top of the exponential moving average: each of the twelve lines is simply an EMA calculated with a different period, weighted toward more recent prices the same way any EMA is. Nothing about the underlying EMA calculation changes; GMMA's contribution is choosing this specific set of twelve periods and plotting them as two color-coded groups so their collective spacing and relative position becomes easier to read than any single EMA could show on its own.

Worked Example

Hypothetical example, for education only.

Suppose a stock has been trading in a narrow range for several weeks. Its short-term group EMAs are clustered close together, for example, the EMA(3) at $48.10, the EMA(8) at $47.95, and the EMA(15) at $47.80, and the long-term group is similarly bunched, with the EMA(30) at $47.40, the EMA(45) at $47.30, and the EMA(60) at $47.20. Both groups sit close together and close to each other: a picture of consensus/consolidation, with little disagreement about price among either short-term or long-term participants.

Now suppose the stock breaks higher over the following weeks. The short-term EMAs react quickly and fan upward, EMA(3) rises to $52.60, EMA(8) to $51.30, EMA(15) to $50.10, while the long-term group, being slower to respond, lags behind at EMA(30) $48.10, EMA(45) $47.60, EMA(60) $47.35. The short-term group has now separated clearly from the long-term group. Read together. This is the pattern commonly described as a strengthening trend: the short-term group moving decisively away from the long-term group rather than the two staying bunched together.

How GMMA Is Commonly Used

Bunching

When either group's six EMAs sit close together, or when the short-term and long-term groups converge toward each other. This is commonly read as consensus or consolidation, a period where the traders that group represents largely agree on price, or where short-term and long-term participants are converging on a similar view.

Separation

When the short-term group moves decisively away from the long-term group, widening the gap between the two, it's commonly read as a strengthening trend. The direction of separation (short-term group above vs. below the long-term group) is read as the trend's direction; the degree of separation is read as a rough gauge of trend strength.

Compression and expansion within a group

Traders also watch the spacing within a single group. A short-term group that fans apart (its six EMAs spreading out from each other) is commonly read as accelerating short-term momentum; one that compresses back together suggests that momentum is fading, independent of what the long-term group is doing.

Crossovers between groups

Some traders also watch for the short-term group crossing through the long-term group as a possible early signal of a developing trend change, though, as with any moving-average crossover, this tends to be more useful alongside separation and price-structure context than read in isolation.

Why GMMA Produces False Signals

  • Choppy or sideways markets, the short-term group can repeatedly separate from and re-converge with the long-term group with no sustained follow-through when price isn't trending.
  • Lag inherent to all twelve inputs, because every line is an EMA of past price, GMMA's read on "strengthening" or "consolidating" always describes what has already happened by the time the pattern is visible.
  • Visual complexity, with twelve lines on the chart at once, it can be easy to focus on a subset of EMAs that supports a conclusion already expected rather than reading the full group objectively.

Common Mistakes

  • Treating any separation as a trade trigger, most traders pair GMMA with price structure, volume, or a trend-strength indicator rather than acting on separation alone.
  • Ignoring which group is leading, a short-term group separating below a flat long-term group communicates something different than a short-term group separating above a rising long-term group; the context of both groups' direction matters.
  • Applying the same period set across very different assets or timeframes without checking whether it still fits, the 3-15 and 30-60 period sets are commonly cited defaults, not fixed rules for every market or chart interval.

Limitations

GMMA is a lagging indicator: all twelve lines are EMAs of past prices, so it confirms a shift in the balance between short-term and long-term participants after it starts rather than predicting it. It also doesn't account for volume, order-book depth, fundamentals, or news catalysts, those need to come from other tools if a complete trading decision requires them.

Reading the Gap Between the Two Groups

The GMMA plots two groups of moving averages, short and long, and the information is in their relationship rather than in any individual line. Compression within a group indicates agreement among participants operating on that horizon; separation between the groups indicates the two horizons have taken different views.

The practical read is about conviction. Widely separated groups moving in the same direction describe a trend that both short-term and long-term participants are supporting. Groups converging describe a trend losing that support, which is a warning that arrives earlier than a crossover would.

The mistake is treating crossovers between individual lines as signals. With a dozen averages on the chart, crossings occur constantly, and reacting to them produces a great many trades from what is meant to be a structural read.

The construction is also entirely moving averages, so it inherits their lag and their behaviour in ranging markets. When price oscillates without direction, both groups compress and interweave, producing a picture that is genuinely uninformative rather than subtly informative.

GMMA FAQs

Who created the Guppy Multiple Moving Average?

Daryl Guppy developed the indicator. It plots two groups of exponential moving averages together to visualize the relationship between short-term and long-term trader activity.

What EMA periods does GMMA use?

The short-term group commonly uses EMA periods of 3, 5, 8, 10, 12, and 15. The long-term group commonly uses EMA periods of 30, 35, 40, 45, 50, and 60.

What does it mean when the GMMA lines are tightly bunched?

Tight bunching within a group, or between the two groups, is commonly read as consensus or consolidation, the EMAs feeding into that group are converging on a similar value, suggesting reduced disagreement about price among the traders that timeframe represents.

What does GMMA separation signal?

When the short-term group separates and moves decisively away from the long-term group. It is commonly read as a strengthening trend, since it implies the two groups' underlying EMAs are diverging rather than converging on a shared price consensus.

Is GMMA a leading or lagging indicator?

Lagging. Every line in both groups is an exponential moving average built from past prices, so GMMA confirms a change in the balance between short-term and long-term participants after it begins rather than predicting it in advance.

Can GMMA be used on its own?

It can be viewed alone, but like any moving-average-based indicator it ignores price structure, volume, liquidity, and broader market conditions, most traders pair it with those factors rather than trading GMMA bunching or separation in isolation.

Why are the averages split into two groups rather than shown as one set?

The design separates shorter averages, taken to represent shorter-term participants, from longer ones taken to represent longer-term holders. Reading the two groups separately is what allows the interpretation that the short group has turned while the long group has not. Displayed as a single undifferentiated set, the relationship the method depends on would be much harder to see.

What does it mean when the short group crosses the long group but does not separate?

A crossing without subsequent expansion is read as a tentative change that longer-term participants have not confirmed. The method treats separation between the groups as the evidence that the change has substance. Crossings that immediately compress again are the most common failure mode, which is why the width of the gap carries more weight in this method than the crossing itself.

Does the indicator work on instruments with limited history?

The longest averages in the set need a substantial history before they produce values, so a recently listed instrument will show an incomplete display for some time. Reading the short group alone during that period discards the comparison the method is built on. Waiting until both groups are fully populated is the straightforward answer.
