The short answer
VWAP for the session average. Lock to freeze the price scale. Hide to mute drawings while you review.
VWAP
Session average. Display only. If a decision needs an average, it must come from the run, not from a chart-only line.
Scale lock
Lock holds the visible high and low so scrolling history does not jump the scale while you compare structure.
Hide
Each drawing kind can be hidden on its own. Lines, fib, box, brackets. Volume and VWAP too.
Where this stops
These controls are for reading history cleanly. They are not alerts. They are not a substitute for a card with a stop.
