Read daily candle behavior (and true premarket/regular/after-hours volume when available) to describe session-specific volume behavior
Answers whether recent sessions show conviction and where volume is concentrating. For equities it reads up to 90 adjusted daily candles and adds an ATR percentage read, using a real premarket/regular/after-hours volume split when a segmented intraday snapshot is available; for crypto it reads up to 60 daily candles without the ATR step and always uses the daily-candle proxy. It computes average candle body, upper/lower wick percentages, open-to-close direction, and a recent-versus-20-day volume spike, then labels bullish or bearish momentum, overhead resistance, or demand support with a technical score. Use it as directional context and note when it falls back to a daily proxy rather than true intraday sessions.
Candle anatomy and volume, with an unusually important caveat about what the data actually is.
Each daily candle is decomposed: the BODY is |close - open|, the upper wick is high - max(open, close), the lower wick is min(open, close) - low. As shares of the full range these describe where trading finished relative to where it travelled. A long upper wick means price reached higher and did not hold there; a large body means the session closed far from where it opened. This is descriptive vocabulary for a bar's shape, not a predictive model.
Volume is compared against its own 20-day average to identify a spike - a ratio, so it is unit-free and scale-normalised. That makes it readable across assets of different sizes; it does not by itself make the readings economically equivalent across different assets or venues.
THE CAVEAT THAT MATTERS MOST. This is called a session volume profile, but a true volume profile distributes traded volume across PRICE LEVELS to find where trading concentrated. What is computed here is candle shape plus a volume ratio. Real premarket/regular/after-hours splits are used only for equities and only when a segmented intraday snapshot is available; for crypto, and for equities without that snapshot, it falls back to a daily-candle proxy. A daily proxy cannot see intraday concentration at all, and the analysis reports which case applies. Read that flag before reading anything else.
On volume generally: it is a measure of activity, not of direction. Every trade has a buyer and a seller, so total volume cannot measure net buying - the transacted quantities match by definition. "Buying volume" is shorthand for BUYER-INITIATED volume, a real microstructure classification meaning the buyer was the aggressor, usually inferred from where the execution sat relative to the quotes. Aggressor buy and sell volumes CAN be imbalanced; total bought and sold quantities cannot.
