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

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.
