Elliott Waves Theory – Contracting and Expanding Triangles

Despite the general belief, Forex markets spend most of the time in consolidation as trends scarcity is the rule of the game. After all, central bank’s mandate of price stability is translating through prices keeping more or less the same levels over an extended period of time. Having said that, the most popular way for a market to consolidate is a triangle. There are many types of triangular formations, with different applications and implications for the patterns that are about to form, but the main two categories are contracting and expanding triangles.

Types of Triangles

A triangle is a three-waves structure, even though it is actually having five different legs. All the legs of a triangle are being labeled with letters, namely a-b-c-d-e and they are corrective. Because of the fact that all of them are corrective, it is being said that a triangle is a three-waves structure as these structures are always corrective. How do we define a triangular formation? The first thing to look for is a series of three higher-highs, lower-lows, or lower-highs, higher-lows. Depending on the time frame they are forming on, triangles can have tremendous implications on the overall Elliott Waves count. In order to represent a triangle or to make it visible, two trend lines need to be drawn: the a-c and b-d trend lines. These trend lines are mandatory to connect the end of the a-wave with the end of the c-wave, respectively the end of the b-wave with the end of the c-wave. It is the nature of these two trend lines that differentiate between triangles. Therefore, a contracting triangle is a triangle that has the a-c and b-d trend lines moving towards a common point in the future, while an expanding triangle, like the name suggests, has the a-c and b-d trend lines moving in opposite directions. Between the two categories, contracting triangles appear most frequently, even though in the Forex market expanding triangles appear more often than when trading other financial instruments like the stock market for example.

Contracting Triangles

contracting and expanding triangles 1These triangles are by far the most common ones to form. They are so common, that there is virtually no time frame in a currency pair that is not experiencing at one moment of time a contracting triangle. As a matter of fact, when doing a top/down analysis using the Elliott Waves theory, the following time frames should be used: monthly, weekly, daily, four hours and hourly ones. At any one moment of time, there is at least one contracting triangle to form on these time frames.
Such a triangle is characterized by all the legs of it to be smaller than the previous one. This is what gives the contracting nature, as the market is forming smaller and smaller moves until eventually, the triangle breaks higher or lower. A contracting triangle can be either a simple correction (in this case it can be either the 4th wave in an impulsive move or the b-wave in a zigzag) or a complex correction. As simple corrections, contracting triangles are not forming that often, but they do appear extremely frequent in complex correction. As a rule of thumb, a complex correction is never starting with a triangle, no matter its nature, and just like that we eliminate a possible place for triangular formation appearance. It means that in a complex correction, a triangle can be either the x-wave or the second or third corrective wave of that respective complex correction. The biggest advantage of contracting triangles, and perhaps the main reason why they are so popular among Forex traders, is the fact that they are really visible. This means that by the time the a-c and b-d trend lines are being drawn, all traders have to do is to wait for the triangle to be completed. This is happening when the b-d trend line is broken. Talking about the b-d trend line, this is by far the most important one between the two trend lines in a triangle, and all eyes are on the moment it is going to be broken. Contracting triangles are consolidation areas, areas when the price is not able to break a specific level and needs to consume time until eventually the area is being cleared. These kind of triangles are forming mostly ahead of important economic releases, and then when the release is coming, the b-d trend line is being broken. Such a trend line is usually being retested, even though such a thing is not really mandatory on all types of triangles. Nevertheless, a good entry point when trading a contracting triangle is to wait for the b-d trend line to be retested before taking a trade.

Expanding Triangles

contracting and expanding triangles 2When compared with contracting triangles, the expanding ones have the a-c and b-d trend lines moving in opposite directions. This is the main reason why these triangles are being characterized by having vicious moves and traders in both categories, bulls, and bears, are most likely to be stopped. Imagine a classical expanding triangle: all the legs of such a triangle should be bigger than the previous one. By the time that the a and b-waves are in place, traders tend to take a position in the direction of the b-wave and having a stop loss at the start of the b-wave. However, as the c-wave is bigger in price than the b-wave, it means the stop is going to be taken. This only attracts new traders in the new direction, as not that the stops are cleared it means a new trend started. This is going to be a costly mistake as the market will retrace and stop those new traders as well due to the fact that the d-wave in such a triangle is bigger than the previous c-wave.
The same is valid for the e-wave, and by the time the triangle is actually breaking, in a totally opposite direction than the one of the e-wave, both bulls and bears already lost their track and no-one really knows where they are with the Elliott count. When the triangle becomes obvious, it is usually too late for taking a new position. In an expanding triangle, the e-wave is by far the most complex structure and the most vicious one as it is the longest out of all the legs. It is so powerful that it will give you the impression that the market will never turn back. Of course that this is only an illusion, but this is the general feeling given by the e-wave.
Expanding triangles are not forming that often as contracting ones, but this statement is valid for classical expanding triangles. We’re going to cover here on our Forex Trading Academy some special types of expanding triangles that are forming in the Forex market on a regular basis. In conclusion, knowing the types of triangles a market can form is a great way to understand corrective waves, both simple and complex ones. The fact that they appear so often is another incentive for taking the time and get to know how to trade such patterns.
