I'm not sure what platform you use, but I "snapped" the trendline to the lows.. meaning I didn't have much artistic license on it. It just snapped between the two lows. Shrug.
It's true, there is always a question of how to approach drawing trendlines. Low to low? Close to Close? Low to Close to Whatever makes the most touches?
I do know that traders with decent sized lots use it to guide their price action, the stuff is in plain view on any tick/volume based charts on most any instrument.
I just thought I'd put the chart up.
