double lower = middle - offset;
Midline.Set(middle);
Upper.Set(upper);
Lower.Set(lower);


if ((High[0] >= KeltnerChannel(3, 20).Upper[0])
&& (High[0] >= SMA (80)[0])

)
DrawDiamond(Time[0].ToString(), 0, High[1] + 45.25* TickSize, Color.Lime);

if ((Low[0] <= KeltnerChannel(3, 20).Lower[0])
&& (Low[0] <= SMA (80)[0])

)
DrawDiamond(Time[0].ToString(), 0, Low[1] - 45.25* TickSize, Color.Red);

}
