Trendlines are an absolute mystery to me. I understand how to create them, I just don't understand the rationale. Taking a simple 2-point TL, if it is broken, the most common thing I see happen is people redrawing it keeping the older point where it is. IE, they typically adjust the later, more recent point

I don't like that either, but I have done it myself a few times. Nevertheless, I think it's to be avoided. But on your thought of "a simple 2-point TL" after much soul searching over the years I've come to feel that a valid trendline should have at least three touches, and the more the better.

As far as the "rationale" of trendlines, beside being a quick gauge of the directional trend of an issue, they sometimes appear to serve as another kind of support or resistance, the same as a moving average or even horizontal S/R. They're just one more type of "indicator" to throw into the soup, regardless of where they may be in one's hiearchy of such.

>>I'm genuinely curious at the thought behind the process.<<

Maybe Shack will find some Long Drawn out ED Lines ... replete with the Overthrow. I'd volunteer but no way could I explain them as eloquently as he.

Until I understood the overthrow .. I used to just capitulate while they Shake the Tree the final time .. now I just try to smile during the overthrow if I was too early. :)

I see that BC has already given you a very creditable (as usual) response..

Just to add one thought which occurs to me on reading your post:

<< if it is broken, the most common thing I see happen is people redrawing it keeping the older point where it is. IE, they typically adjust the later, more recent point.>>

What that statement may miss is that the more recent point only emerges after it becomes evident that the extreme of a new {minor recession} {minor advance} has been recorded. So the new more recent point does have some significance.....

As BC indicates, there are some features of trend lines which affect their :"character/importance/durability"...A 3-point touch, as BC notes; length of time a line has been in effect; steepness of angle of ascent or descent....(some of the things I've touched on, for example in taking about AAPL and TIE lately)...
