I've been studying the 7-2-08 morning more closely to see how I might have traded it given my current level of understanding. I numbered the relevant bars in the attached chart.
Bar 4: Enter short due to LM FBO on IBV
Bar 6: Hold short even though it's an OB, because it FBOs the upper end of LM.
Bar 14: From Bar 6 to now there haven't been any signals to reverse long. But I'll assume that I was mistakenly anticipating an up Channel to develop based on the fact that we already had the blue CO Traverse. Bar 14 shows Extreme IRV with a close off the low in LM. I might have mistakenly drawn a down Traverse with an FT3 on Bar 14 and thought, here we go for the third leg of our up Channel.
Bar 17: We got 3 bars of DBV to get us up to the same level as the high of the day established earlier, and Bar 17 shows an IBGS on DBV. Red is clearly dominant and WMCN for an up Channel did not. Therefore, we have a clear signal to reverse short to get back on the right side of the market. So I reverse short and profit from my mistaken long reversal on Bar 14 ("First by accident, then by design," to quote our mentor).
Now that we know that down is the dominant direction, it becomes easy to hold for a nice, long run. When I have some time later on, I plan to study on whether one could have held through the non-dominant up Traverse that formed the second leg of the Channel. If so, then one could have held short all the way from Bar 17 to Bar 78, EOD.
Which brings up a 3rd area of weakness for me: knowing when to hold through a non-dominant Traverse and when to reverse into it.
