The lines are supposed to be a help. That's why I suggested them way back when (and by "way back" I'm talking several years). But at some point, they can and generally do become a hindrance. If I were mentoring somebody, I'd know when to tell him to move on and put the lines behind him, so to speak. But I have no control otherwise over who does what and how and for how long and to what extent. Thus some/many people "fail" with the lines and conclude that they're useless. But they are rather a device.
If you need them, use them, and don't feel bad about it. But remember that the goal is to do without, to have as clean a chart as is humanly possible.
Consider, therefore, the following:
You have to see the hinge to begin with. If you do, you obviously see also the midpoint. You see that price has risen from the apex of the hinge and is returning to the midpoint of the hinge, perhaps to test it. This test occurs and price bounces off that level about 15m before the open. If you take the long, and there's no reason why you shouldn't (if you wait until the open, you won't likely be filled), you're good until price reaches 78.
For whatever reason, buyers choke at 78. You don't need to know why because this is where the demand line comes in. It's broken. You exit. You stand aside. When price reaches 73 and attempts to recover, it fails to do so, and down becomes the line of least resistance, even though all this is happening at a level higher than 50% of the rally (71).
So you short. You may have to exit and re-enter a couple of times, but you won't lose anything, and if you can wait to see if price is able to exceed any previous swing high, there's no reason to exit at all until after you hit 57. You may notice also that all that congestion from 1015 to 1100 centers around the 50% level of the rally (again, 71), and once that goes, it goes.
The only line you "need", then, is the first demand line. After that it's a series of failures to breach the preceding swing high, and, eventually, a capitulation.
