Composite profile

Window, not session

A session profile resets at every open. A composite profile does not: it accumulates volume by price over whatever window you define, so a level that was heavily traded three days ago still shows as a high volume node today. The POC and value area of a composite are therefore statements about the whole window, and they change slowly.

Composites are used for the structural map: where the large nodes and thin gaps are across a swing, where a naked POC from a past session still sits, and whether today's value is inside or outside the longer-term distribution.

• Fixed composite: a set of whole sessions (for example the last five days).
• Rolling composite: a window that slides with the current bar.
• Anchored composite: from a chosen bar or event to now.

Reading a composite next to a session profile

• A session POC inside a composite high volume node is trade happening where the market has long agreed; a session POC inside a composite low volume node is trade in a zone the market usually crosses quickly.
• Composite value area edges are slower references than session edges; a session breaking its own VAH while still inside composite value is a smaller event than one leaving both.
• The larger the window, the more the composite smooths over any single day; it is meant to.

In Senzoukria

On the heatmap screen, the Profile history setting is described in the app as the depth of history the volume profile and the POC / VAH / VAL lines are built on, accumulated live and independently of the heatmap ring, with a retroactive switch. The Volume profile panel there is explicitly traded volume by price over that profile history, not the session, even when zoomed out, and the POC / VA / VWAP levels follow the same window. That panel is a rolling composite.

On the footprint chart, the Volume Profile (session) overlay is not limited to the session: its Period setting offers 3 days, weekly, 3 months and 6 months rolling, and visible range, and its hint states that the 90/180-day options roll back from the latest loaded candle, use only real price-level data, and that selecting a period does not load history. The Market Profile (TPO) overlay has the same rolling 90 and 180-day periods. The Rolling VPOC indicator computes the POC of the aggregated profile of the last N bars (default 10), and Naked POC keeps each past session's untouched point of control.

Common mistakes

• Reading the heatmap's profile as a session profile. It is built over the profile history window; the app's hint says so.
• Comparing a composite POC with yesterday's session POC as if they were the same kind of level.
• Building a composite over a window with a data gap and reading the hole as a low volume node. Missing history is missing; it is not thin.
• Assuming a long window is always better. A composite that spans a regime change blends two distributions into one.
• Selecting a 90 or 180-day period and expecting it to fetch history. The overlay's hint states that the period only uses data already loaded.
