Turning Point, Peak, Trough, Swing High, Swing Low, and ZigZag
To recognize the geometric shape in our chart, we need a measurable object. In financial market, the geometric recognition is done in the two dimension of price and time. Price is usually placed in Y axis and time is usually placed in X axis. In financial market, we recognize the geometric shapes in the candlestick chart. Some might use range bar chart. In this book, we will be using candlestick chart most of time because they are easy to read.
When we look at the plain chart, we can recognize almost nothing. It is because we do not know which object we will be studying in the continuous price series. For an object to be measurable, the object requires boundary or outline. Hence, to recognize any geometric shapes in our chart, we need a good logic of dividing the continuous price series into some measurable objects. Typically, it is best to start with Peak Trough Analysis.

In Peak Trough Analysis, we define peak and trough in an alternating manner. The analysis will start from oldest price data to latest price data. If we start with peak, then we will detect trough, peak, trough, peak, and so on to the right. If we start with trough, then we will detect peak, trough, peak, trough, and so on to the right. Each peak and trough requires having the certain distance in price and time as shown in Figure 1.2-2. Doing this manually could be quite tedious. Fortunately, there is a Zigzag indicator available everywhere to do this task automatically. At the same time, we provide Peak Trough Analysis free for audience of this book. Please refer to the downloading guide for Peak Trough Analysis tool in this book.

Once the Peak Trough Analysis is done, your chart will look like this. What peak trough analysis is doing here is that turning the continuous price series into many triangles. Three points are equivalent to one triangle. For example, a set of peak, trough, and peak can form one triangle. Likewise, a set of trough, peak, and trough can form one triangle too. When we just label peak and trough, you might notice the presence of these triangles (Figure 1.2-3). However, if we provide the outline to each triangle, then you could see them more clearly (Figure 1.2-4).

The triangles created from Peak Trough Analysis is now measurable because they have triangular boundary (i.e. outline). In financial trading, we use these triangles to make the geometric prediction. Hence, Peak Trough Analysis is the important preliminary analysis to start with.

So far, we have covered definition of peak and trough in our chart. In the trading community, trader tends to use swing high and swing low instead of the term “Peak” and “Trough”. Hence, many traders interchangeably use swing high with peak. Likewise, people interchangeably use swing low with trough too.
At the same time, people can use the term “Turing Point”. “Turing Point” is slightly different because “Turning Point” includes both peak and trough. It is like the word limb including both arms and legs. In addition, people might use the term “zigzag” in place of turning point. This is probably inspired from the Zigzag technical indicator. The term “zigzag” also includes both peak and trough. Each terminology can be used in slightly different context elsewhere. For example, Peak and trough are the terms used in many scientific literature whereas swing low and swing high are specific in trading community. However, in this book, we might use these terms interchangeably.
