Where's the point of control, and how far does the value area actually reach?

How this is calculated

• The point of control (POC) is simply the price level with the single highest volume in your list.
• The value area starts at the POC and grows one level at a time, always adding whichever untaken neighbor, the next level up or the next level down, carries more volume. On a tie, this calculator adds the level above, the same tie-break this site's own volume profile strategy simulation uses. Growth stops the moment the value area's combined volume reaches 70% of the session total, the standard value-area threshold used across most retail and professional volume-profile implementations.
• The value area high (VAH) and value area low (VAL) are just the top and bottom price levels the growth step above ends up including, not a fixed percentage band around the POC.
• This calculator works from whatever price levels you paste in. A coarser set of levels (wider price increments) produces a coarser, faster-converging value area than a finer set over the same data, the same real trade-off a live platform's own bucket size setting makes for you.
