In this chapter, we will extend the library implementation to the possibility of creating multi-window interfaces for the MQL applications. We will also develop a system of priorities for left mouse clicking on graphical objects. This is required to avoid problems when elements do not respond to the user's actions.
At the current stage of development, the library for creating graphical interfaces contains a form and several controls that can be attached to it. It was mentioned before that one of the future articles would be dedicated to the multi-window mode. Now, we have everything ready for that and we will deal with it in the following chapter. In this chapter, we will write classes for creating the status bar and tooltip informational interface elements.

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.
It is essential to detect whether a market is flat or not for many strategies. Using the well known ADX we demonstrate how we can use the Strategy Tester not only to optimize this indicator for our specific purpose, but as well we can decide whether this indicator will meet our needs and get to know the average range of the flat and trend markets which might be quite important to determine stops and targets of the markets.

MetaTrader 5 features hedging position accounting system
In order to expand possibilities of retail Forex traders, we have added the second accounting system — hedging. Now, it is possible to have multiple positions per symbol, including oppositely directed ones. This paves the way to implementing trading strategies based on the so-called "locking" — if the price moves against a trader, they can open a position in the opposite direction.
Let us consider the button control. We will discuss examples of several classes for creating a simple button, buttons with extended functionality (icon button and split button) and interconnected buttons (button groups and radio button). Added to that, we will introduce some additions to existing classes for controls to broaden their capability.
