Where did price open relative to value?
MARKET STRUCTURE · OPEN ANALYSIS · STANDARD
Market Profile open analysis: where price opened versus the prior session's value area, the open type (Open Drive, Open Test Drive, Open Rejection Reverse, or Open Auction In Range), and what it implies for the rest of the session.
Where did price open relative to value?
Pick an instrument and a past session date. I'll compare the open to the prior session's value area and classify the open type: Open Drive, Open Test Drive, Open Rejection Reverse, or Open Auction In Range.
What is "open type" in Market Profile terms?
One of four classic Market Profile open types: Open Drive (opens outside value, extends immediately with no pullback), Open Test Drive (tests back toward the open/value area first, then drives), Open Rejection Reverse (opens outside value, fails to extend, reverses), or Open Auction In Range (opens inside value, balanced, no clear direction yet).
Where does the "prior session value area" come from?
The value area (VAH/VAL/VPOC) is computed from the previous UTC session's candles using TPO (Time Price Opportunity) bucketing, the same method used by Market Profile charting platforms. The current session's open price is then located relative to that range.
Which exchanges and instruments does this support?
Binance and Bybit perpetual futures, the two adapters in this codebase with a live candle-fetch endpoint. Pick any date up to yesterday (UTC) — the current, still-forming session can't be fully analyzed yet.
What does "tails and single prints" mean?
A tail is a thin, quickly-rejected price extreme at the session high or low (few TPO prints), often marking a level defended by aggressive buyers or sellers. A single print is a price level touched by exactly one TPO letter, a sign of a fast, low-interest move through that price.
Is this the same as candlestick or support/resistance analysis?
No. Market Profile groups time at each price level (TPO) rather than just plotting price over time, which is how it derives a statistically-weighted value area and point of control instead of a visually-drawn support/resistance line.
