In general, to calculate an angle on a line is just
atan(abs((y2-y1)/(x2-x1)) * 180 / pi
I would like to calculate the angle of a 34 ema, possibly the last
10-15 bars. I started off like this:
Take a linear regression line through the 34 ema:
array = LinearReg(EMA(Close, 34), 10);
angle = atan(abs(array[BarCount-1] - array[BarCount-11])/10.0) *
180 / 3.1459;
What I'm finding is that the angle is way too small in comparison to
that I'm seeing on the screen. It's as though using the x-axis with
just bar counts is throwing off the slope.
Any ideas greatly appreciated,
Steve
