Another tool I use is something called Prorated Volume.
With PRV, you can determine an expectation of volume for an entire time-based bar within the first few seconds or minutes of the bar forming. On the inverse, armed with a PRV expectation, you gain "sight" of increasing or decreasing volume, again, way before the bar is completely formed.
As I mentioned...
Price can go up, price can go down, volume can increase, volume can decrease.
The work is to study those possible combinations and see what works for YOUR personality and style of trading. No volume = no price discovery.
