Yep, I have another thing I am trying to understand, see chart attached please.
Do you know the difference between tapes, traverses and channels? Your illustration shows a short traverse fanning into two larger short channels with incomplete long annotations.
Channels are built from traverses which are built from tapes which are built from 2 bar combinations.
Clarity will come as you do complete annotations and explore the price/volume relationship. Current Volume (or lack of anticipated volume) will support discerning the difference between your posted examples.
Generally, if increased volume doesn't support the BO, it will fail. This is due to the tape/traverse/channel one is observing is a non-Dominant move in a larger Dominant context. The failure though is observed on the larger Dominant context as a new fanned Channel pt3.
There are exceptions but it's better to understand the basics before the nuances.
