Elliott Waves Theory – Types of Zigzag Patterns

A zigzag is a corrective wave and it is considered to be a three waves structure. Being a corrective wave, it means it is labeled with letters and not with numbers: a-b-c. The beauty of a zigzag comes from the fact that both waves a and c are impulsive waves, while only the b wave is a corrective one. This means that while the overall a-b-c pattern is a corrective one, two parts of it are actually impulsive! It goes without saying that a zigzag is the only corrective wave that resembles impulsive activity and traders are often mistaken these two patterns. In a way, it is only normal for this to happen due to the fact that there are actually two impulsive waves of a lower degree within the overall zigzag. Like it was the case with the flat patterns, zigzags are of multiple types as well. They are not that diversified like flats, but still, there are three types of zigzags to consider.

The Key Stays with the C-Wave

If in the case of a flat pattern, the b-wave retracement was the thing that defined different types of flats, for zigzags, the b-wave retracement is crystal clear: it should not end beyond 61.8% of the previous a-wave. Having said that, the only element to differentiate between different types of zigzags is the c-wave. Before moving forward, please consider again that the c-wave in a zigzag is always an impulsive wave. As a general rule, it is not possible for the c-wave to be shorter than the b-wave in any zigzag pattern, so this option should be ruled out from the start.

C-Wave is Smaller than 61.8% of A-Wave

zigzags1This represents the least frequent situation when the c-wave exceeds the end of the previous a-wave, but it is less than 61.8% of it. Once again, the golden ratio proves to be essential in deciding what kind of a pattern the market will form. Having said that, the logical thing to do is to measure the length of the a-wave, take 61.8% out of it, and project it from the end of the b-wave. Keep in mind that it is mandatory for the c-wave to end beyond the end of the previous a-wave. If the resulting 61.8% measured move is not enough for that, it means the whole pattern is actually not a zigzag. This type of zigzag is really important as it calls for a sharp retracement into the opposite direction, so by the time price moves beyond the end of the a-wave, a powerful countertrend move should be expected. The distance to be covered is minimum 80% of the whole zigzag and more often it goes beyond full retracement. Therefore, we can safely say that this type of zigzag is one that should be rather faded by the time price goes beyond the end of the a-wave.

C-Wave’s Length is Between 61.8% and 161.8% of the A-Wave

zigzags2This is by far the most common setup for a zigzag and, if I were to put some percentages, I would say that almost ninety percent of all zigzags are falling into this category. Because they are so common, such zigzags are being called normal zigzags. In order to trade a normal zigzag, one should look for a five waves structure to be completed for the a-wave. This should be followed by a retracement of minimum 1% for the b-wave (in the case the b-wave is a running correction, don’t expect it to retrace much into the territory of the just completed a-wave), but no more than 61.8%. The truth is that the more the b-wave advances into the territory of the a-wave, the less likely the overall pattern to be a zigzag. Therefore, a retracement more than 38.2% and into the 50% should be taken with a grain of salt and considerations for another pattern should influence the technical analysis picture from this moment on. It is often that the a-wave and c-wave, or the two impulsive waves, are similar in both construction and length. Therefore, if the a-wave is a 3rd wave extension impulsive wave, chances are that the 5th wave will be a similar one as well. In order to trade such a zigzag, the way to go is to set a take profit equal to the length of the a-wave, posted on top of the b-wave. Even in a double or a triple zigzag, normal zigzags are expected to form rather than other types of zigzags.

C-Wave is Bigger than 161.8% of the A-Wave

zigzags3This uncommon situation happens most of the times when the whole zigzag is part of a triangle, usually a contracting triangle. Such a zigzag is either the entire leg of the triangle or just a part of it. It is highly unlikely that this zigzag is part of a double or a triple zigzag, but most likely, if it is to be part of a complex correction, most likely that one is a double or triple combination. Between the two complex corrections, the most likely price will form a double combination rather than a triple one. If the a-wave is an impulsive wave with a 3rd wave extension, look for the c-wave to be either a 5th wave extended impulsive wave or a 3rd wave extension but with a very small 2nd wave. It is typical for small second waves in impulsive moves to be followed by a super-extended third wave and this explained very well the fact that the c-wave is that long. All three types of zigzags are important in understanding how complex correction function and how they were classified by Elliott. In fact, understanding simple corrections, like zigzags and flats, is just the first step in understanding complex corrections as these ones are being formed by simple corrections as well, connected by an x wave. So far we looked at the types of flat and zigzag patterns, but the most common simple correction is yet to follow. I’m talking about triangle types and how to interpret them, and this will be the subject of our next article here on Forex Trading Academy: contracting and expanding triangles.
