View of Technical Analysis in the Context of Automatic Control Systems (ACS), or "Reverse View"

The article demonstrates an alternative view of technical analysis, which is based on the principles of both the modern automatic control theory and technical analysis itself. It is an introductory article representing the theory with some practical applications of it.

  1. Which do not work under optimization. And DebugView which work always:
    /** Log
    * send information to OutputDebugString() to be viewed and logged by
    * SysInternal's DebugView (free download from microsoft) This is ideal for
    * debugging as an alternative to Print(). The function will take up to 10
    * stringa (or numeric) arguments to be concatenated into one debug message.
    //*/
    #import "kernel32.dll"
       void OutputDebugStringA(string msg);
    #import
    void Log(string s1,    string s2="", string s3="", string s4="", string s5="",
             string s6="", string s7="", string s8="", string s9="", string s10=""){
        if (IsDllsAllowed()){
            string out  = WindowExpertName() + ": "
                        + s1 + s2 + s3 + s4 + s5 + s6 + s7 + s8 + s9 + s10;
            OutputDebugStringA(out);
        }
    }
    
  2. An in the tester/visual mode you can call PauseTest()
    /*                                          PauseTest
    // http://forum.mql4.com/35112
    // Each chart consists of two windows (i.e. two hWnds): the drawing area (WH,)
    // and a container (GA.) There is then a standard MDI container which holds all
    // the chart windows (GA1.) And that sits inside the main MT4 window (GA2.)
    */
    #include <WinUser32.mqh>
    #import "user32.dll"
      int GetAncestor(int, int);
    #import
    void PauseTest(){   datetime now = TimeCurrent();   static datetime oncePerTick;
        if( oncePerTick != now  )if( IsTesting()
        )if( IsVisualMode()     )if( IsDllsAllowed()    ){  oncePerTick = now;
            for(int i=0; i<200000; i++){        // Delay required for speed=32 (max)
                if (IsStopped()) break;         // http://forum.mql4.com/32837 WH-DL
                int main = GetAncestor(WindowHandle(Symbol(), Period()), 2);//GA_ROOT
                if (i==0) PostMessageA(main, WM_COMMAND, 0x57a, 0); // 1402. Pause
        }   }
        // The PostMessage above sends the command to the main terminal. Thus it
        // only affects the active chart window. To maximize a window for example
        // must activate it first. http://forum.mql4.com/35336#538848
        // See also SetForgroundWindow(h) http://codebase.mql4.com/source/25962
    }
