A simple replacement for a comment. Works in the tester 50 times faster than the standard function.

It is known that the standard "Comment" function slows down the tester very much.

Here is an example of code and its execution time in the tester.

void OnTick()    {     MqlTick tick;     SymbolInfoTick(_Symbol, tick);     if(tick.ask != 0 && tick.bid != 0)       {        string str = StringFormat("ask  = %.5f\nbid  = %.5f\ntime = %s", tick.ask, tick.bid, TimeToString(tick.time, TIME_DATE | TIME_SECONDS));        Comment(str);       }    }  //+------------------------------------------------------------------+

Just add the code #include <Comm.mqh>

#include <Comm.mqh>  //+------------------------------------------------------------------+  void OnTick()    {     MqlTick tick;     SymbolInfoTick(_Symbol, tick);     if(tick.ask != 0 && tick.bid != 0)       {        string str = StringFormat("ask  = %.5f\nbid  = %.5f\ntime = %s", tick.ask, tick.bid, TimeToString(tick.time, TIME_DATE | TIME_SECONDS));        Comment(str);       }    }  //+------------------------------------------------------------------+

14 seconds !!!

14 seconds instead of 11 minutes 28 seconds

11*60+28=688, 688/14=49, 49 times faster!!!

Example of usage with default settings.

No need to declare an instance of the class.

#include <Comm.mqh>  //+------------------------------------------------------------------+  void OnTick()    {     string str = "PROGRAM_NAME = " + MQLInfoString(MQL_PROGRAM_NAME) + "\n" + (string)TimeCurrent();     Comment(str);    }  //+------------------------------------------------------------------+

Example of use with the ability to change settings.

#include <Comm.mqh>  //+------------------------------------------------------------------+  void OnTick()    {     string str = "PROGRAM_NAME = " + MQLInfoString(MQL_PROGRAM_NAME) + "\n" + (string)TimeCurrent();     Comment(str, _Xpx, _Ypx, _clrText, _FontSize, _clrBack, _Transparency, _Font, _corner);    }  //+------------------------------------------------------------------+

Example of using multiple instances of a comment.

#include <Comm.mqh>  CComm comm1;  CComm comm2;  CComm comm3;  CComm comm4;  //+------------------------------------------------------------------+  void OnTick()    {     MqlTick tick;     SymbolInfoTick(_Symbol, tick);     if(tick.ask != 0 && tick.bid != 0)       {        string str = StringFormat("ask  = %.5f\nbid  = %.5f\ntime = %s", tick.ask, tick.bid, TimeToString(tick.time, TIME_DATE | TIME_SECONDS));        Comment(str);        comm1.Comm(str, _Xpx, _Ypx + 80, _clrText, _FontSize, _clrBack, _Transparency, _Font, _corner);        comm2.Comm(str, _Xpx + 10, _Ypx + 20, _clrText, _FontSize, clrGreen, _Transparency, _Font, CORNER_LEFT_LOWER);        comm3.Comm(str, _Xpx + 30, _Ypx, clrGreen, _FontSize, _clrBack, _Transparency, _Font, CORNER_RIGHT_LOWER);        comm4.Comm(str, _Xpx, _Ypx + 50, clrBlack, _FontSize, _clrBack, _Transparency, _Font, CORNER_RIGHT_UPPER);       }    }  //+------------------------------------------------------------------+
