Developing a Replay System — Market simulation (Part 17): Ticks and more ticks (I)
Developing a Replay System — Market simulation (Part 17): Ticks and more ticks (I)
Here we will see how to implement something really interesting, but at the same time very difficult due to certain points that can be very confusing. The worst thing that can happen is that some traders who consider themselves professionals do not know anything about the importance of these concepts in the capital market. Well, although we focus here on programming, understanding some of the issues involved in market trading is paramount to what we are going to implement.
Brute force approach to patterns search (Part VI): Cyclic optimization
Brute force approach to patterns search (Part VI): Cyclic optimization
In this article I will show the first part of the improvements that allowed me not only to close the entire automation chain for MetaTrader 4 and 5 trading, but also to do something much more interesting. From now on, this solution allows me to fully automate both creating EAs and optimization, as well as to minimize labor costs for finding effective trading configurations.
Trade transactions. Request and response structures, description and logging
Trade transactions. Request and response structures, description and logging
The article considers handling trade request structures, namely creating a request, its preliminary verification before sending it to the server, the server's response to a trade request and the structure of trade transactions. We will create simple and convenient functions for sending trading orders to the server and, based on everything discussed, create an EA informing of trade transactions.
Developing a quality factor for Expert Advisors
Developing a quality factor for Expert Advisors
In this article, we will see how to develop a quality score that your Expert Advisor can display in the strategy tester. We will look at two well-known calculation methods – Van Tharp and Sunny Harris.
Permuting price bars in MQL5
Permuting price bars in MQL5
In this article we present an algorithm for permuting price bars and detail how permutation tests can be used to recognize instances where strategy performance has been fabricated to deceive potential buyers of Expert Advisors.
Structures in MQL5 and methods for printing their data
Structures in MQL5 and methods for printing their data
In this article we will look at the MqlDateTime, MqlTick, MqlRates and MqlBookInfo strutures, as well as methods for printing data from them. In order to print all the fields of a structure, there is a standard ArrayPrint() function, which displays the data contained in the array with the type of the handled structure in a convenient tabular format.
Alternative risk return metrics in MQL5
Alternative risk return metrics in MQL5
In this article we present the implementation of several risk return metrics billed as alternatives to the Sharpe ratio and examine hypothetical equity curves to analyze their characteristics.
StringFormat(). Review and ready-made examples
StringFormat(). Review and ready-made examples
The article continues the review of the PrintFormat() function. We will briefly look at formatting strings using StringFormat() and their further use in the program. We will also write templates to display symbol data in the terminal journal. The article will be useful for both beginners and experienced developers.
Studying PrintFormat() and applying ready-made examples
Studying PrintFormat() and applying ready-made examples
The article will be useful for both beginners and experienced developers. We will look at the PrintFormat() function, analyze examples of string formatting and write templates for displaying various information in the terminal log.
How to create a simple Multi-Currency Expert Advisor using MQL5 (Part 2): Indicator Signals: Multi Timeframe Parabolic SAR Indicator
How to create a simple Multi-Currency Expert Advisor using MQL5 (Part 2): Indicator Signals: Multi Timeframe Parabolic SAR Indicator
The Multi-Currency Expert Advisor in this article is Expert Advisor or trading robot that can trade (open orders, close orders and manage orders for example: Trailing Stop Loss and Trailing Profit) for more than 1 symbol pair only from one symbol chart. This time we will use only 1 indicator, namely Parabolic SAR or iSAR in multi-timeframes starting from PERIOD_M15 to PERIOD_D1.
Another MQL5 OOP Class
Another MQL5 OOP Class
This article shows you how to build an Object-Oriented Expert Advisor from scratch, from conceiving a theoretical trading idea to programming a MQL5 EA that makes that idea real in the empirical world. Learning by doing is IMHO a solid approach to succeed, so I am showing a practical example in order for you to see how you can order your ideas to finally code your Forex robots. My goal is also to invite you to adhere the OO principles.
DoEasy. Controls (Part 32): Horizontal ScrollBar, mouse wheel scrolling
DoEasy. Controls (Part 32): Horizontal ScrollBar, mouse wheel scrolling
In the article, we will complete the development of the horizontal scrollbar object functionality. We will also make it possible to scroll the contents of the container by moving the scrollbar slider and rotating the mouse wheel, as well as make additions to the library, taking into account the new order execution policy and new runtime error codes in MQL5.
Wrapping ONNX models in classes
Wrapping ONNX models in classes
Object-oriented programming enables creation of a more compact code that is easy to read and modify. Here we will have a look at the example for three ONNX models.
DoEasy. Controls (Part 7): Text label control
DoEasy. Controls (Part 7): Text label control
In the current article, I will create the class of the WinForms text label control object. Such an object will have the ability to position its container anywhere, while its own functionality will repeat the functionality of the MS Visual Studio text label. We will be able to set font parameters for a displayed text.
DoEasy. Controls (Part 3): Creating bound controls
DoEasy. Controls (Part 3): Creating bound controls
In this article, I will create subordinate controls bound to the base element. The development will be performed using the base control functionality. In addition, I will tinker with the graphical element shadow object a bit since it still suffers from some logic errors when applied to any of the objects capable of having a shadow.
DoEasy. Controls (Part 2): Working on the CPanel class
DoEasy. Controls (Part 2): Working on the CPanel class
In the current article, I will get rid of some errors related to handling graphical elements and continue the development of the CPanel control. In particular, I will implement the methods for setting the parameters of the font used by default for all panel text objects.
DoEasy. Controls (Part 1): First steps
DoEasy. Controls (Part 1): First steps
This article starts an extensive topic of creating controls in Windows Forms style using MQL5. My first object of interest is creating the panel class. It is already becoming difficult to manage things without controls. Therefore, I will create all possible controls in Windows Forms style.
