The indicator detects and displays 3 Drives harmonic pattern (see the screenshot). The pattern is plotted by the extreme values of the ZigZag indicator (included in the resources, no need to install). After detecting the pattern, the indicator notifies of that by a pop-up window, a mobile notification and an email. The indicator highlights the process of the pattern formation and not just the complete pattern. In the former case, it is displayed in the contour triangles. After the pattern is complete, a potential reversal zone appears on the chart. The basic pattern proportions are set in the parameters. Intermediate ratio values are calculated proportionally. The indicator features CD_accuracy parameter defining the accuracy of cd/bc ratios. For example, if cd/bc = 1.0 and accuracy is set to 0.1, the indicator uses the range 0.9 .. 1.1
