Running MQL5 Program Properties

To obtain information about the currently running mql5 program, constants from ENUM_MQL_INFO_INTEGER and ENUM_MQL_INFO_STRING are used.

For function MQLInfoInteger

ENUM_MQL_INFO_INTEGER

Identifier	Description	Type
MQL_HANDLES_USED	The current number of active object handles. These include both dynamic (created via new) and non-dynamic objects, global/local variables or class members. The more handles a program uses, the more resources it consumes.	int
MQL_MEMORY_LIMIT	Maximum possible amount of dynamic memory for MQL5 program in MB	int
MQL_MEMORY_USED	Memory used by MQL5 program in MB	int
MQL_PROGRAM_TYPE	Type of the MQL5 program	ENUM_PROGRAM_TYPE
MQL_DLLS_ALLOWED	The permission to use DLL for the given running program	bool
MQL_TRADE_ALLOWED	The permission to trade for the given running program	bool
MQL_SIGNALS_ALLOWED	The permission to modify the Signals for the given running program	bool
MQL_DEBUG	Indication that the program is running in the debugging mode	bool
MQL_PROFILER	Indication that the program is running in the code profiling mode	bool
MQL_TESTER	Indication that the program is running in the tester	bool
MQL_FORWARD	Indication that the program is running in the forward testing process	bool
MQL_OPTIMIZATION	Indication that the program is running in the optimization mode	bool
MQL_VISUAL_MODE	Indication that the program is running in the visual testing mode	bool
MQL_FRAME_MODE	Indication that the Expert Advisor is running in gathering optimization result frames mode	bool
MQL_LICENSE_TYPE	Type of license of the EX5 module. The license refers to the EX5 module, from which a request is made using MQLInfoInteger(MQL_LICENSE_TYPE).	ENUM_LICENSE_TYPE
MQL_STARTED_FROM_CONFIG	Returns true if a script/EA is launched from the StartUp section of the configuration file. This means that the script/EA had been specified in the configuration file the terminal was launched with.	bool

For function MQLInfoString

ENUM_MQL_INFO_STRING

Identifier	Description	Type
MQL_PROGRAM_NAME	Name of the running mql5-program	string
MQL5_PROGRAM_PATH	Path for the given running program	string

For information about the type of the running program, values of ENUM_PROGRAM_TYPE are used.

ENUM_PROGRAM_TYPE

Identifier	Description
PROGRAM_SCRIPT	Script
PROGRAM_EXPERT	Expert
PROGRAM_INDICATOR	Indicator
PROGRAM_SERVICE	Service

ENUM_LICENSE_TYPE

Identifier	Description
LICENSE_FREE	A free unlimited version
LICENSE_DEMO	A trial version of a paid product from the Market. It works only in the strategy tester
LICENSE_FULL	A purchased licensed version allows at least 5 activations. The number of activations is specified by seller. Seller may increase the allowed number of activations
LICENSE_TIME	A version with a limited term license

Example:

   ENUM_PROGRAM_TYPE mql_program=(ENUM_PROGRAM_TYPE)MQLInfoInteger(MQL_PROGRAM_TYPE);
   switch(mql_program)
     {
      case PROGRAM_SCRIPT:
        {
         Print(__FILE__+" is script");
         break;
        }
      case PROGRAM_EXPERT:
        {
         Print(__FILE__+" is Expert Advisor");
         break;
        }
      case PROGRAM_INDICATOR:
        {
         Print(__FILE__+" is custom indicator");
         break;
        }
      default:Print("MQL5 type value is ",mql_program);
   //---
   Print("MQLInfoInteger(MQL_MEMORY_LIMIT)=", MQLInfoInteger(MQL_MEMORY_LIMIT), " MB");
   Print("MQLInfoInteger(MQL_MEMORY_USED)=", MQLInfoInteger(MQL_MEMORY_USED), " MB");
   Print("MQLInfoInteger(MQL_HANDLES_USED)=", MQLInfoInteger(MQL_HANDLES_USED), " handles");
