The Wing Patterns indicator scans for many different kinds of Patterns using an XABCD structure. The term Wing Pattern is used to refer to all types of patterns based on a general XABCD structure, which is plotted in an alternate high-low extreme form. If you connect these points on a chart, it usually looks like the wings of a butterfly, thus the name Wing Pattern. These patterns fit very well with the Harmonic patterns. Other patterns that can be searched are stored in an external file.
