Библиотека для расчета формул. Формула задается строкой. Можно задавать формулу в строковой переменой в окне свойств. Формула может включать арифметические действия "+-/*" и все функции кроме MathRand(): abs(), arccos(), arcsin(), arctan(), sin(), cos(), tan(), exp(), log(), mod(), max(), min(), pow(), ceil(), sqrt(), log10(), floor(), round(). Кроме этого в формулу могут входить числа (если число дробные, то разделитель точка) и аргументы. Аргумент начинается с буквы "а" (латинская) и номера
In this article we will perform an experiment: we will color optimization results. The color is determined by three parameters: the levels of red, green and blue (RGB). There are other color coding methods, which also use three parameters. Thus, three testing parameters can be converted to one color, which visually represents the values. Read this article to find out if such a representation can be useful.
The MetaTrader 5 platform features functionality for saving trading reports, as well as Expert Advisor testing and optimization reports. Trading and testing reports can be saved in two formats: XLSX and HTML, while the optimization report can be saved in XML. In this article we consider the HTML testing report, the XML optimization report and the HTML trading history report.
The article demonstrates the development of the ZigZag indicator in accordance with one of the sample specifications described in the article "How to prepare Requirements Specification when ordering an indicator".

All patterns from Encyclopedia of Chart Patterns by Thomas N. Bulkowski in one indicator. It draws an up or down arrow whenever a pattern is identified. Patterns are selected in the drop-down list of the Pattern variable (located at the beginning of the properties window). The indicator has numerous external parameters, some of them apply to all patterns, while others are selective. To see more information on the parameters used for the selected pattern, enable the ShowHelp variable (located at
Indicator of Stowell's Three-Bar Net Line. In this indicator, the number of bars used for determining the lines can be defined in the settings. With the default settings, the indicator draws arrows in the areas of the line breakout. The lines are not displayed on the chart by default. but can be enabled. Parameters Alerts - enable alerts when arrows appear. Arrows appear on a forming bar and can disappear during bar formation. Therefore, it is recommended to wait for the bar with the arrow to
The article considers all kinds of divergence: simple, hidden, extended, triple, quadruple, convergence, as well as divergences of A, B and C classes. A universal indicator for their search and display on the chart is developed.
The article provides the analysis of the following patterns: Flag, Pennant, Wedge, Rectangle, Contracting Triangle, Expanding Triangle. In addition to analyzing their similarities and differences, we will create indicators for detecting these patterns on the chart, as well as a tester indicator for the fast evaluation of their effectiveness.
