Decorating Indicators – MetaTrader 4

admin — Wed, 18 Nov 2009 02:27:44 +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).

C++ and MQL5 – MetaTrader 5

admin — Mon, 16 Nov 2009 04:27:42 +0000

People have been asking if the code of MetaTrader 5 (MQL5) will be similar to C++?

It was promised that MQL5 will be very similar to classic C / C++, except:

pointers. that staff with *.
goto operator.
anonimous enumeration.
some exotic staff from so-called “object-oriented programming”: classes constructors do not have parameters, no multiply inheritance etc.

From discussion of the already-made MQL5 help file (means “beta” version of MQL5 is ready), I can say that MQL5 will be VERY close to C. Great improvement will be structures.

The MQL5 Help file can be downloaded from http://www.mql4.com/files/mql5.chm
