Cant use +=, wont return desired return.

Question

Hello,

Cant understand why += wont sum in this context my variable difCP .

if(CurrentBar < 1) return;


DateTime MyDateTime9 = new DateTime(Time[0].Year,Time[0].Month, Time[0].Day, 09, 30, 0);
DateTime MyDateTime16 = new DateTime(Time[0].Year,Time[0].Month, Time[0].Day-1, 16, 00, 0);



                    Print("time"+ChartBars.GetBarIdxByTime(ChartControl, MyDateTime9));
                    Print("time"+ChartBars.GetBarIdxByTime(ChartControl, MyDateTime16));        

      double difCplus = 0;

     double closePrice16 = Bars.GetClose(Bars.GetBar(MyDateTime16));
     double closePrice9 = Bars.GetClose(Bars.GetBar(MyDateTime9));

      double    difCP = closePrice16 - closePrice9;



      difCplus += difCP;

                  Print("dif"+difCP);
                  Print("CP"+closePrice16);
                  Print("CP"+closePrice9);
                Print("DP"+ difCplus);

                  double candle = Close[0] + difCplus;

                  Print("Can"+candle);

difCplus is Printed does not return a cumulative sum.

-2,10,-2

it should return -2, 8, 6

TY

Hi

label6.Text=DateTime.Now.Month.ToString()+"/"+DateTime.Now.Year.ToString();
      for (int i=1;i<13;i++)
      {
        comboBox1.Items.Add(dt.GetMonthName(i).ToString());
      }

//Cant use +=
