Ok... if you mean the blue one, the smaller range from just the overnight, referring to this new chart, I mark a swing low from the overnight at C. We can see that on the same bar where price rejects at B, price makes it below C to get to D. So the fact that we made a lower low is of some significance.You're getting ahead of yourself again. None of this is available to you in real time.
For the moment.
Now, consider what you have to use once price has failed to exceed "B" (ignore everything after "B"):
![]()
With regard to your first "ranging" rectangle, what can you look for to tell you whether traders intend to go back to ranging after price has left "B" or possibly initiate a trend downwards?
If your question refers to the larger red trading range... well... it probably can't because at this point we don't even know this will be a wider range yet, so your question must refer to the blue one.
