Over time (running a few laps), they become simply differentiable. Most days can be subdivided in their relative activity. Open (very active), then things slow, then pick up, then Close (very active). It is simple enough to assign legs to each of these regions. Some days are more differentiable than others, but this is the strength of properly annotating channels. I'm far from a guru, but if your tuned to traverses & retraces, the shifts tend to be more relaxing, but that is just personal experience. Your Q is indeed important and definitely relates to what can be anticipated. There is indeed a 3rd channel in which volume does have unique characteristics. Fortunately, doing exactly what needs to be done when it is required keeps you with and even ahead of the activity.
Yes, I know, I need to update my YM. I usually do as few updates as possible so that confidence is instilled. It will only have been the second update for the day...
Adjusted... The current YM may be a bit steep. Continuing to monitor.
I'm showing the FTT on the YM that I previously missed trying to stay with posting to ET. NO EXCUSES tho! ... I left the HOLD that I continued on the ES thru YM FTT into Leg 2...
