Please Help about draw moving average line

1. t2a5c2k9:
   I want to draw blue line after red line
   My opinion want to use MA lag and have predict line ( blue line ). May be use constant value to create it.
   Based upon the image, you want to extend the back shifted MA

   #define MA_PERIOD 14
   #define MA_SHIFT  -5
   #define MA_METHOD  0 // MODE_SMA
   #define MA_PRICE   PRICE_CLOSE // ?
   int start(){
      double currMA = iMA(NULL, 0, MA_PERIOD, MA_SHIFT, MA_METHOD, MA_PRICE, 0),
             prevMA = iMA(NULL, 0, MA_PERIOD, MA_SHIFT, MA_METHOD, MA_PRICE, 1),
             slope  = currMA - prevMA;
      Tline("predict", Time[-MA_SHIFT], currMA, Time[-MA_SHIFT-1], currMA+slope, Blue, true);
   }
   void TLine( string name, datetime T0, double P0, datetime T1, double P1
             , color clr, bool ray=false ){                #define WINDOW_MAIN 0
       if      (ObjectMove( name, 0, T0, P0 ))     ObjectMove(name, 1, T1, P1);
       else if (!ObjectCreate( name, OBJ_TREND, WINDOW_MAIN, T0, P0, T1, P1 ))
           Alert("ObjectCreate(",name,",TREND) failed: ", GetLastError() );
       else if (!ObjectSet( name, OBJPROP_RAY, ray ))
           Alert("ObjectSet(", name, ",Ray) failed: ", GetLastError());
       if (!ObjectSet(name, OBJPROP_COLOR, clr )) // Allow color change
           Alert("ObjectSet(", name, ",Color) [2] failed: ", GetLastError());
       string  P0t = PriceToStr(P0);           if (MathAbs(P0 - P1) >= Point)
               P0t = StringConcatenate(P0t, " to ", PriceToStr(P1));
       if (!ObjectSetText(name, P0t, 10))
           Alert("ObjectSetText(",name,") [2] failed: ", GetLastError());
   }
   string  PriceToStr(double p){ return( DoubleToStr(p, Digits) ); }

   But i 'm newbie for mt4 then i don't know how to code it.
   No Slaves here, learn to code or pay someone. We're not going to code it FOR you. We are willing to HELP you.
