A Virtual Order Manager to track orders within the position-centric MetaTrader 5 environment for MetaTrader 5
This class library can be added to an MetaTrader 5 Expert Advisor to enable it to be written with an order-centric approach broadly similar to MetaTrader 4, in comparison to the position-based approach of MetaTrader 5. It does this by keeping track of virtual orders at the MetaTrader 5 client
Auto-Generated Documentation for MQL5 Code for MetaTrader 5
Most Java coders will be familiar with the auto-generated documentation that can be created with JavaDocs. The idea is to add comments into the code in a semi-structured way that can then be extracted into an easy to navigate help file. The C++ world also has a number of documentation

enum incorrect branch in switch
I have a bug in my code in which a switch statement branches to the wrong case for a user-defined enum. Here's the code which reports the incorrect enum. When m_LogLevel == LOG_VERBOSE (4), the function returns LOG_DEBUG. But unfortunately when I try to distill the problem down to a small example

Preventing decompilation of MQL5 executables
Could I get a comment please from MetaQuotes on what steps if any they have taken to make MQL5 difficult to decompile? As I understand it, the optimising MQL5 compiler delivers machine code, but even this may not be sufficient, see example of a mainstream .exe locker http://www.eziriz.com/
