I seldom frequent this site any longer, any even less frequently post.
However your chart is a blast from the past and brings back fond memories. I haven't seen HL only bars for years.
It appears you once followed the AHG thread, so I am compelled to respond. The username shortskirt also helps, I am a sucker for the ladies lol...
anyway, I have a great respect for Anek. He was instrumental in developing my TA skills and success as a trader. In that regard, I promised to never divulge any information he shared privately, which I will always honor. So I do not post chart's with TA analysis. The concepts are not mine to share...
That being said.... I believe that the TL concept was originally shared in the AHG thread, so I feel comfortable commenting on it.
In this particular case, the key concept is Trend line fanning. DBphoenix threads are very good reference. I suggest you review his thread
In your SS, I would move the TL because a HH was plotted and the original TL was breached twice. If it were only breached once, I would monitor it along with the newly drawn TL.
Regarding your copied "channel TL" imho the correct starting point is always between the first two anchor points, your TL has three touches, so you "could" move it to the place you started yours. Your example is an old obvious trend, you could actually treat it as an ascending triangle, rather than a parallel channel, just a thought...
As a rule I normally do not move channel lines, if a TL is fanned, I may create a new channel line. Then either monitor both if still valid by my rules or suppress the original.
TA is more art than science.
Good luck and watch out for brisk winds. lol... 
If DB, NoDoji respond to your post. I would pay attention, there are a few others. but the majority of ET, I would take with a grain of salt, actually a cup of salt...
