Delta & Cumulative Delta
Overview
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.
Key Concepts
Positive delta = more aggressive buying than selling, Negative delta = more aggressive selling, Cumulative delta divergence from price = weakening move, Delta at specific price levels shows who has control, Volume delta POC shows where most aggression occurred
Entry Signals
Bullish price + bullish delta = healthy trend (continuation), Rising price + falling cumulative delta = bearish divergence (reversal setup), Falling price + rising cumulative delta = absorption (bullish reversal), Delta extreme spike + price reversal = exhaustion
Exit Signals
Delta divergence trades: enter when price reverses after divergence confirmation, Exit if delta re-aligns with price direction, Use delta to confirm or reject candle patterns
Best Timeframes
Tick charts, 1M, 5M, 15M for active trading; 30M+ for analysis
Pro Tips
Delta analysis works best in liquid futures markets (ES, NQ, CL) where real volume data is available. Crypto exchange volume may include wash trading. Forex 'volume' is tick volume, not true order flow.

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.
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.
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.
Order Book & Liquidity Analysis
Order book and liquidity analysis examines the distribution and behaviour of resting orders across all price levels to map where significant liquidity pools exist. By aggregating order book data over time through heatmaps and liquidity visualisations, traders can identify where large players intend to transact, anticipate areas of support and resistance, and gauge market microstructure health.
