Beitrag MQL's OOP notes: Particle Swarm Speeds Up Expert Adviser Optimization On The Fly veröffentlicht

In 2 previous chapters we have studied a library for on the fly optimization of expert advisers (part1, part2). One of drawbacks of the library is its slow method of optimization, because it's nothing else than straightforward iteration over all possible combinations of parameters' values...

Beitrag Lightweight html5-tools for tester report and statement analysis veröffentlicht

Quite often there is a need to analyze html-documents, generated by MetaTrader 4. Since the tester in MetaTrader 4 supports only one work symbol at once, multicurrency expert advisers are usually tested by running many separate tests for different work symbols one by one...

Are you ready for a very very long story? It will be probably most complicated and prolonged publication in the series of MQL OOP so far, but it's surely worth reading, because its main theme is automatic self-optimization of expert advisers on the fly...

Beitrag MQL's OOP notes: rubber arrays, safe numbers, exceptions handling and other tricks: part 1 veröffentlicht

Today we're starting a patchy subject, which will combine many different things. This is why I decided to split it into parts. Out final goal is exception handling, but before we can address it, we need to prepare a ground...

Beitrag Optimizing Walk-forward Optimization for Newbies veröffentlicht

WalkForward optimization is very powerful and popular method of EA examination and tuning. Some time ago I have released WalkForward library (WFO) and WalkForward reporter script for MetaTrader. They support several modes and flexible setup, yet they seem a bit complicated for ordinary users...

Beitrag MQL's OOP notes: Self-made profiler on static and automatic objects veröffentlicht

MQL code performance is important in many aspects. For example, if your expert adviser is well optimized you could pay much less for it running in the cloud. Or you can eliminate a situation when your terminal becomes unresponsive for a while while it calculates a heavy indicator...

Beitrag MQL Script for Charts Synchronization veröffentlicht

Traders do often work with many charts simultaneously. And one of common use cases is when they need to compare 2 charts visually. This is handy, for example, if you test an expert adviser and want to view multiple resulting charts (for different parameters) side by side...

Beitrag MQL's OOP notes: Object hierarchies and serialization veröffentlicht

When it comes to OOP, there should be an hierarchy of classes. And most of hierachies are built from a single base class. This is very powerful feature. It allows you to store objects in various containers, such as vectors, queues, lists, and process them consistently in batch tasks...

Beitrag MQL's OOP notes: Singleton, Command queue, and Template method patterns in simple order manager veröffentlicht

As the title says this time we'll try to implement a simple object-oriented framework for trading. It's surely simple as a framework, but is probably most complex thing among all that we've discussed so far in the MQL's OOP notes...

Beitrag MQL's OOP notes: HashMap supports old-fashioned indicators in MetaTrader 5 veröffentlicht

MetaTrader 5 is not back compatible with MetaTrader 4 in many aspects. This is bad, but we can do nothing with this. Yet we can do something to simplify translation of MetaTrader 4 products into MetaTrader 5...

Beitrag MQL's OOP notes: Multiple timers with publisher/subscriber design pattern and abstract class veröffentlicht

Every expert and indicator in MetaTrader can have a timer. From time to time a novice MQL developer asks a question: what should I do if I need many timers? The answer is simple: use a single timer with lesser period to manage and dispatch all other timer events with larger periods...

Beitrag MQL's OOP notes: Managing resources by object wrappers veröffentlicht

MQL programmers use files here and there. Standard API provides a set of file functions which employ old plain procedural approach. But sometimes it's better to upgrade this style up to OOP. One simple use case where OOP can be helpful is related to resource control...

Beitrag MQL's OOP notes: Print data using overloads and templates veröffentlicht

One of the most frequently used MQL functions is Print. It's simple and indispensable. Unfortunately it usually requires a lot of routine typing which makes code bulky. For example, if you need to print several values, you need to explicitly add some separators...
