A study showing how much volume traded at each price level rather than in each time period.
Price moves fast where nobody is and stalls where everybody is. The lookback period determines every level, so anchor it to real structure and then leave it alone.
A price level on a volume profile at which an unusually large quantity has traded.
A great many participants transacted there, and every one of them has a reason to act if price returns.
A price level on a volume profile at which almost nothing has traded.
An air pocket. Nobody holds a position there to defend or to escape, so price travels through it quickly — useful for setting expectations about speed, not for choosing an entry.
