Graphical Interfaces II: Setting Up the Event Handlers of the Library (Chapter 3)
The previous articles contain the implementation of the classes for creating constituent parts of the main menu. Now, it is time to take a close look at the event handlers in the principle base classes and in the classes of the created controls. We will also pay special attention to managing the state of the chart depending on the location of the mouse cursor.
MetaTrader 5 features hedging position accounting system
In order to expand possibilities of retail Forex traders, we have added the second accounting system — hedging.

Added to that, we will introduce some additions to existing classes for controls to broaden their capability.
This is the final chapter of the second part of the series about graphical interfaces. Here, we are going to consider the creation of the main menu. The development of this control and setting up handlers of the library classes for correct reaction to the user's actions will be demonstrated here. We will also discuss how to attach context menus to the items of the main menu. Adding to that, we will mention blocking currently inactive elements.

Fuzzy logic to create manual trading strategies
This article suggests the ways of improving manual trading strategy by applying fuzzy set theory.
