Order Flow Trading
Delta, cumulative volume delta, footprint charts, volume profile, and real-time market microstructure analysis.
Overview
Order flow trading peer beneath the candle to analyse the actual buy and sell orders executing in the market. By studying delta (the difference between aggressive buyers and sellers), volume profile, and footprint charts, traders gain insight into where institutional participants are placing size and how supply-demand dynamics shift in real time.
Topics Covered
Delta & Cumulative Delta
Delta is the difference between aggressive buying volume (market orders hitting the ask) and aggressive selling volume (market orders hitting the bid) within a candle or time period. Cumulative delta tracks the running total over time. Divergence between price and cumulative delta reveals whether rallies/selloffs have genuine buyer/seller conviction.
Footprint Charts
Footprint charts display the actual volume traded at each price level within a candle, broken down by aggressive buyers (market orders hitting the ask) and aggressive sellers (market orders hitting the bid). This granular view reveals exactly where buying and selling pressure occurs, exposing absorption, exhaustion, and imbalance patterns invisible on standard charts.
Volume Profile Analysis
Volume Profile displays the total volume traded at each price level over a specified period (session, week, month, or visible range). Unlike time-based volume histograms, volume profile shows WHERE trading activity concentrated. Key levels include the Point of Control (POC), Value Area, and High/Low Volume Nodes.
Point of Control (POC)
The Point of Control is the single price level at which the most volume was traded during a specified period. It represents the 'fair value' according to market participants and acts as a magnet — price tends to gravitate toward the POC. The naked POC (from a prior session that was never revisited) is one of the most reliable support/resistance levels in order flow trading.
Value Area High / Low
The Value Area is the price range containing approximately 70% of a session's or period's total traded volume. The Value Area High (VAH) is the upper boundary and Value Area Low (VAL) is the lower boundary. These levels act as dynamic support/resistance and are central to market profile and volume profile trading strategies.
Market Profile
Market Profile organises price data into 30-minute periods called TPOs (Time Price Opportunities), creating a bell-curve distribution that reveals market behaviour patterns. Developed by J. Peter Steidlmayer at the CBOT, Market Profile identifies day types (Normal, Trend, Double Distribution, etc.) and provides a statistical framework for understanding auction market theory.
Absorption & Exhaustion
Absorption occurs when large limit orders absorb aggressive market orders without allowing price to move. For example, price hits a level where heavy sell market orders are absorbed by even larger buy limit orders — the aggression is neutralised. Exhaustion is when aggressive buying/selling loses momentum, visible through declining delta and volume at price extremes.
