Yes, look at the bottom there are other lines that follow way more points than the line you have drawn & same with the top. It is a visual representation of the average therefore the strongest line has the most points bouncing off/ around it. I would take the top line that has 4 points connected vs yours with 1 point. And I would take the bottom line ~5 points than yours with 2. In addition there is a shit ton of movement in the middle of this channel you're completely ignoring by not including a regression line. For the support/ resistance yours are actually pretty good. Also, remember things can break out of the channel and that is indicative of it trying to break trend.
