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");
