# 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.

## 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.
