Concept family
Volume & Order Flow
Volume studies, VWAP, volume & market profile, delta, and order-flow microstructure.
Volume and order-flow analysis reads market activity rather than price alone, on the reasoning that participation reveals conviction. The tools span generations: cumulative lines such as OBV and the Accumulation/Distribution Line keep running totals of volume signed by each bar's price action, behavioral measures like Relative Volume put current activity in context, and VWAP ties intraday trade to the average price paid.
A second strand reorganizes the chart itself. Volume Profile and TPO-based Market Profile distribute activity across price levels rather than across time, showing where the market found acceptance and where it was rejected. Order-flow tools go finer still, splitting volume into aggressive buying and selling to produce delta, footprint, and imbalance reads. These methods lean on data quality: on many platforms delta is estimated from tick direction rather than true bid and ask attribution.

Volume Profile
The most extensively covered concept in this family: a histogram of traded volume by price that converts raw activity into a map of accepted and rejected levels.
30 indicators
Volume Delta
Aggressive buy volume minus aggressive sell volume per bar, the raw material for cumulative delta, delta profiles, and divergence reads.
10 indicators
Session VWAP
The running volume-weighted average price for the trading day, an execution benchmark for institutional desks and a widely watched intraday reference for value.
1 indicators
Cumulative flow lines
Price-and-volume composites such as OBV, the Accumulation/Distribution Line, and the Money Flow Index that track whether volume is flowing with or against the trend, with divergence from price as the classic warning.
Volume behavior
Direct reads of volume itself, from Relative Volume and spike detection to dry-ups and breakout confirmation, used to judge whether a move attracted unusual participation.
VWAP family
Volume-weighted average price in session, anchored, periodic, and rolling forms, differing in where the average starts and how far it reaches back, with bands and regime reads built on top.
Volume profile
Histograms of volume by price whose landmarks, from the Point of Control to the Value Area and high- and low-volume nodes, map where the market did sustained business and where it moved through quickly.
Market profile / auction theory
The TPO framework that treats each session as an auction, reading Initial Balance, single prints, and balance versus imbalance to judge whether the market is accepting value or searching for it.
Order-flow & microstructure
Execution-level tools, from volume delta and footprint charts to the DOM and liquidity heatmaps, that read aggressive flow against resting liquidity to locate absorption, sweeps, and imbalances.
VSA (volume spread analysis)
A bar-by-bar method in the Wyckoff lineage that compares volume against a bar's spread and close to identify no-demand conditions, stopping volume, and climactic action.
