How to read angle of trend line ? - page 3

[Christian Ricard]

Hi,

Find the angle:

double FindTLineAngle(const datetime Date1,const double Price1,const datetime Date2,const double Price2)
   {
      double dAngle = 0.0;
      int x1,y1,x2,y2;
      bool bResult1 = ChartTimePriceToXY(0,0,Date1,Price1,x1,y1);
      bool bResult2 = ChartTimePriceToXY(0,0,Date2,Price2,x2,y2);
      
      if(bResult1 && bResult2)
      {
         double a = MathAbs(y1-y2);
         double c = MathAbs(x1-x2);
         
         double dArcTan = atan(a/c);
         dAngle = dArcTan*(180/M_PI);
      }
      return(dAngle); 
   }
