Using Neural Networks In MetaTrader

MetaTrader Global — Thu, 19 Nov 2009 16:42:32 +0000

Many of you probably have considered the possibility of using neural networks in your EA. This subject was very hot specially after 2007 Automated Trading Championship and the spectacular winning by Better with his system based on neural networks. Many internet forums were flooded with topics related to neural networks and Forex trading. Unfortunately writing native MQL4 implementation of NN is not easy. It requires some programming skills and the result would not be very efficient specially if you’d like to test your final result in tester on large number of data.

In this article I’ll show you how you can use the freely available (under LGPL), renowned Fast Artificial Neural Network Library (FANN) in your MQL4 code while avoiding certain obstacles and limitations. Further I assume that reader is familiar with Artificial Neural Networks (ann) and terminology related to this subject so I’ll concentrate on practical aspects of using particular implementation of ann in MQL4 language.

Decorating Indicators – MetaTrader 4

MetaTrader Global — Tue, 17 Nov 2009 20:32:57 +0000

Introduction

What is an indicator? It is a tool intended for displaying a certain type of data. Usually it is information about the price series properties, exactly this type of indicators will be considered further.

Each indicator also has its own properties and characteristics: for example, the range of values, the overbuying/overselling zones, the line crossing, tops and bottoms… They are numerous and can be successively used together with the main indicator values. However, such properties are not always vivid. The reasons can be different – small size of the indicator window, lower concentration, etc.

The purpose of this article is to help you to improve the descriptive and informational value of indicators, as well as partial automation and facilitation of the code implementation process. I hope the code below will cause no difficulties both for professional developers and beginners.

The article is intended for those who have at least the starting level of MQL4 knowledge and can implement simple ideas and algorithms in a code, as well as knows about the structure of code storage in the terminal and can use the libraries (experts/libraries) and header files (experts/include).

MetaTrader Tips – Expert Advisor Installation

MetaTrader Global — Fri, 13 Nov 2009 02:09:37 +0000

MetaTrader Expert Advisors file should have the file extension of .ex4 (compiled code) or .mq4 (sourse code). First it is necessary to copy this file to the folder Experts of the MetaTrader working directory (usually C:\Program Files\MetaTrader Broker Name or MetaTrader).

The second step is to restart MetaTrader. After the restart the expert should be added to the list of experts in the Navigator window. It necessary to stress that the colored icon corresponds to mq4 file. If you have an ex4 file only, an icon in the window Navigator will be grey. The same grey color may mean that the errors in a source code appeared.

In order to check errors in the EA, you can press F4, the editor of language MQL4 , and then it is necessary to load the source code of expert into the editor. Press F5 in order to compile the expert advisor. In case of success, the sentence ’0 errors’ will appear in conclusion window. Warnings are not errors and their presence does not hinder the successful compiling.

In this article I would like to pay special attention to the program files folder of MetaTrader 4 client terminal. This is connected with the fact that already during the first meeting of the terminal and during all the other time of the serious work with it we often face the necessity to refer to the contents of this folder. So it would be very useful to study the purpose of all its contents.

Program Files of the MetaTrader 4 Terminal

If you do not change any settings during the installation of mt4setup.exe distribution file, all program files of the terminal will be installed in the following directory: “C:\Program Files\MetaTrader”.
