Rather than let this lesson go to waste, I'll point out here that this current activity provides an example of when and where and why to segue from AMT trading to SLA trading (see post #101).
The trades all day have centered around trading this range, long at the LL and short at the UL, all of which is strictly AMT (if one had drawn a bunch of lines within the range, he never would have held from one end to the other).
But if and when price breaks out of the range, which it eventually must, one can switch to the SLA since the AMT trades are for the time being done. This means letting price make a swing point, as it did at 1335, so that your DL can be drawn if you absolutely have to draw it. If you want to backfit your line to the LL of the range, you're welcome to do so, but it's easier to see what's going on if you don't draw it at all. The main thing to remember is to let price make that retracement so that you can judge the level of demand. If the "retracement" turns into a reversal, so what? But if it's confirmed, then you have some extra points to put in your pocket.
Edit, 1430: And now the stride is broken. What are you going to do? How much room are you going to give price so that it can tell you what it want to do? Are you going to exit immediately? Give it a point or two? This has to be decided in advance. It's up to you to define "break".
Note: if price penetrates the previous swing, which it will not do in a nice trend, then you most likely have a problem. Remember that re-entry is always an option.
Edit: 1456: Today just keeps on giving in terms of lessons. Note here that after the stride was broken, there was a retracement in the downmove at 1440-1445. If one were to follow the rules and go short there, he'd be stopped out for 3-4pts when price changed its mind and advanced past the retracement high at 68+. Those are the breaks. But 3-4pts after a 32pt move is essentially tithing.
