RTH only — 9:30 to 16:00 ET. Every number on every page under /vpoc-data/ is filtered to U.S. Regular Trading Hours. Pre-market, overnight, and post-close events are parsed from the session log but excluded from all aggregates. Counts, durations, distances, time-of-day distributions — all RTH-only.
Your own sessions can include ETH if you want. VPOC Migration Pro ships with three session presets — Globex (18:00 ET start, full overnight + RTH), RTH (09:30 ET start, pit hours only), or Custom (any start time in quarter-hour increments). The addon's session log captures whichever preset you run; the public stats on this site happen to focus on the RTH portion. If you trade the overnight session and want ETH coverage in your own logs, just set the addon to Globex or Custom — auto-reset will fire at your chosen boundary.
A note on terminology: the addon's log starts a new "segment" every time it resets — auto-reset at the session boundary, toggle off/on, Bookmap restart, or a settings change. Internally that's how the data is grouped. None of the public stats on this site are normalized by log segment because that number reflects how often the addon was restarted, not anything about the market. All averages on these pages are per trading day, which is the meaningful denominator.
Every page is built directly from VPOC Migration Pro's session log — a plain-text file the addon writes locally as it tracks Volume Point of Control migration in real time. Each line is timestamped to the second.
A VPOC shift is logged the moment the addon promotes a new price level to "current VPOC" — meaning that price now has more accumulated session volume than any other. A Naked touched event fires when price returns to a prior VPOC that hadn't been revisited yet. A DVPOC changed event fires when the Developing VPOC swaps to a different candidate. (Note: DVPOC = Developing VPOC throughout this site — the live intraday challenger to the current VPOC. Some traders use the same acronym for the Daily VPOC, the prior day's settled point of control; that's a different concept. What's the difference?)
These pages aggregate across sessions to surface patterns — direction skew, time-of-day activity, frequency of Naked touches — that aren't visible inside any single session. Sample size grows as more sessions log.
