In chart above, the most important line to 2850 by 10/08 thesis is the blue trend line. In #139, price broke the orange trend line (not in chart above because it does not matter anymore). This development means that we are now on red line until 2700. It also means that there should be limited 2-way vol until at least 2685. This means that even though 2650 is the top of this channel, I don't have reason to expect a "big" retrace more than 30 points in this area (if that). So the worst I see at 2650, is 2620, before 2685 and eventually 2700.
I expect 2700 to hit this Tuesday. I also expect a retrace to 2650-ish or to channel line. This check down will create "the purple trend line" which will be the trend line to 2750. After purple trend line breaks, blue trend line is the line for 2850. Finally, the break of blue trend line means top is in for this rally and price should correct until support at gray trend line.
