Don't apologize but you're not bursting my bubble, yet! ( but I'm open to having it deflated). I've heard this knock off before and let's put it to bed if we can.
Did you try zooming the chart? Both x and y? Surely the slope of the plotted line changes as you move both the x, abscissa and the ordinate, price, but the calculated values of the slope from using linregslope does not. I think of the slope as representative of the rate of change of that price (or other) array. I don't know what Eckhardt said or in what context he said it. Maybe he was talking about using pencil and paper. There the scaling on the chart would make a difference. Also, you have to ask yourself, why would Tomasz have coded a linregslope function, or Dimitris Tsokakis and others used it so frequently in their work on the forum? In my collection alone of valued AFL clips I get 200 hits by many different users of this board.
