Metatrader 5 / Metatrader 4 for MQL5 / MQL4 articles preview

MQL5 Freelance is an online service where developers get paid for creating trading applications ordered by traders. Now, traders understand the difference between all the services on MQL5.com: a ready-made Trading Robot can be bought from the MetaTrader Market, while a unique Expert Advisor that trades based on a specific user-defined strategy can be ordered in the Freelance service. Experienced developers compete for traders' order implementation, so that a trader can select the one who offers the best time and cost conditions. Since the launch of the service, traders have paid a total of $600,000 for 10,000 jobs performed

Updated MetaTrader 4 Web platform: support for technical indicators and 9 new languages

The developments on expanding the web platform features are in full swing. Our immediate and most important objective is to provide web traders with technical analysis tools. To address this task, we have started adding technical indicators into the web platform.

We have completely revised the chart display model making it possible to apply multiple indicators simultaneously. The indicators can be displayed in a selected symbol window, as well as in a separate one. The ability to configure the indicator parameters has also been implemented. At the moment, our developers and QA specialists are thoroughly testing all the features to ensure stable operation of analytical tools.

Introduction

This article is the continuation of the first part of the series about graphical interfaces. The first article Graphical Interfaces I: Preparation of the Library Structure (Chapter 1) explains in detail what this library is for. A complete list of links to the articles of the first part is at the end of each chapter. There, you can also download a complete version of the library at the current stage of development. The files must be placed in the same directories as they are located in the archive. In the previous article, the CWindow class was extended with additions that allowed moving the form over a chart. Now, the form controls react to mouse cursor movements. In this article, we will continue the development of the CWindow class and enrich it with methods that will permit us to manage the form by clicking on its controls. We will enable the program to be closed by a form button as well as implement a minimizing and maximizing feature for the form.

The trading system by Bill Williams described in his book called "New trading dimensions" is certainly something that any trader is familiar with. This is one of the systems that contains clear and understandable rules for a majority of beginners. But the simplicity of rules is only apparent — the trading system comprises more than a dozen of trading patterns.
Many have attempted to create an Expert Advisor themselves based on this system, but pattern formalization, correct search and interpretation frequently prove difficult. In order to automate trading as well as identify and mark the system patterns, I have developed a module of trading signals for creating robots in MQL5 Wizard. I aimed to create maximum convenience for those potential users of the MetaTrader 5 terminal, who may wish to study the trading system independently. The difference of the suggested trading module from other 60 published modules for MQL5 Wizard is that it contains configuration options with a visual interface.

Your MQL4/MQL5 indicator or Expert Advisor may be the most efficient in the world but there is always a room for improvements. In most cases, you need to enter the program's settings to change its inputs. However, this step can be avoided.
Develop your own control panel based on Standard Library classes. This will allow you to change the settings without restarting a program. Besides, this will make your program more attractive allowing it to stand out from the competitors. You can browse through multiple graphical panels in the Market.
In this article, I will show you how to add a simple panel to your MQL4/MQL5 program. You will also find out how to teach a program to read the inputs and react to changes of their values.
