Learn order flow,
footprint and GEX.

Choose from 5 paths: orderflow, liquidity, options flow, quantitative research and software selection. Start with the inputs and their limits. 2 of these guides carry a figure you can handle.

  1. I am starting with orderflow

    Read the footprint

    Start with executed trades, then learn delta, imbalances and absorption-like observations. Build a repeatable reading routine before testing a strategy.

    1. 01Order flow trading for beginnersChoose one instrument and understand the inputs
    2. 02How to read a footprint chartRead bid volume, ask volume and delta
    3. 03Order flow imbalance explainedCompare diagonal volumes and threshold conventions
    4. 04Crypto orderflow charts: footprint, delta and heatmapDistinguish exchange-specific spot and perpetual data

  2. I want to understand liquidity

    Read the order book

    Learn what was displayed, what traded and what the available data cannot establish. Keep observations separate from assumptions about intent.

    1. 01How to read the DOMRead the spread and displayed depth
    2. 02Liquidity heatmap explainedFollow resting liquidity through time
    3. 03OFI explained (the order-book model)Measure changes in book pressure
    4. 04The Microstructure indicator: micro-price & QIUnderstand micro-price and queue imbalance

  3. I am learning options flow and GEX

    Connect options and futures

    Separate option transactions from modeled exposure. Check timestamps, units and positioning assumptions before interpreting levels.

    1. 01Options flow trading: premium, sweeps and activityRead premium, volume, sweeps and classification limits
    2. 02What is GEX (Gamma Exposure)?Calculate gamma exposure with stated assumptions
    3. 03Gamma walls: call & put wallDistinguish open interest from gamma concentrations
    4. 04Zero gamma (gamma flip) levelInterpret modeled zero crossings and their limits

  4. I want to test a trading idea

    Start quantitative research

    Turn a chart observation into an explicit rule, preserve the data available at each decision and evaluate later periods after costs.

    1. 01Quant trading for beginners: from idea to backtestDefine an experiment you can reject
    2. 02Futures backtesting: costs, replay and walk-forwardCheck execution assumptions, costs and walk-forward splits
    3. 03Hurst exponent & mean reversionExplore a model and its sampling limitations

  5. I am choosing software and data

    Build a suitable setup

    Compare the tools you need, data entitlements and full subscription cost. Confirm account permissions separately from charting capabilities.

    1. 01Best order flow trading software (2026)Evaluate documented features with one repeatable checklist
    2. 02Can you get footprint charts for free?Distinguish free data, demonstrations and paid software
    3. 03Rithmic footprint software: native R | ProtocolVerify connection eligibility and historical coverage
    4. 04Footprint software with GEX includedCheck the combined footprint and options workflow

Everything, by topic.

Glossary · 14 termsA word in the way? It is defined here, next to the guide that explains it.
Options flow
Observed option transactions or activity summaries for specified contracts. Trade size alone does not establish opening intent or directional exposure.
Quant trading
Trading research and decisions expressed as explicit rules evaluated on data, with costs, timing and uncertainty documented.
Order flow
Executed trades and changes in displayed orders for a specified market. Trade-side classification describes liquidity taking, not participant identity.
Footprint chart
A chart that groups executed volume by price within each bar, often separating bid-side and ask-side volume using a documented classification.
Delta
Buy-aggressor volume minus sell-aggressor volume over a defined interval. The result depends on the feed, classification and quantity unit.
Cumulative delta (CVD)
Trade delta accumulated from a defined reset point. Divergence from price is an observation to investigate, not proof that a move must reverse.
Imbalance
A volume ratio evaluated against a threshold. A common footprint convention compares ask volume with bid volume one tick below; zero-denominator handling must be specified.
Absorption
Substantial aggressive volume with limited price progress, consistent with passive liquidity meeting it. The observation alone does not identify a participant or guarantee a reversal.
DOM (depth of market)
A ladder of displayed resting orders or aggregated size by price. Depth can change or be cancelled; it does not reveal private intent or all hidden liquidity.
Liquidity heatmap
A time history of displayed order-book depth, encoded by size and color scale. Interpreting executions versus cancellations requires the corresponding event data.
Volume profile · POC · value area
Executed volume grouped by price over a chosen period. POC is the highest-volume price bucket; the value area uses a configured fraction and allocation method.
VWAP
The sum of price times volume divided by total volume over a specified interval. It is a benchmark; crossing it does not itself establish a trading signal.
GEX (gamma exposure)
An aggregate estimate of options gamma exposure under stated position, sign and unit conventions. Its interpretation is conditional on the model and snapshot.
Hurst exponent
An estimate of scaling behavior over specified data and horizons. Persistence interpretations depend on the process and estimator; finite-sample bias can be substantial.

Questions, answered

Everything we get asked twice. Anything else — ping us.

Orderflow trading studies executed trades and changes in displayed liquidity. Footprint, delta, DOM and heatmap views organize different parts of that data. The observations do not identify participants or guarantee future direction.

Choose one instrument and feed, learn bid/ask volume and delta, then compare executions with displayed depth. The beginner track leads through footprint reading; the software track explains data and subscription choices.

Options flow describes transactions or activity in option contracts. GEX estimates aggregate gamma exposure using option data and positioning assumptions. Both require a source and timestamp; neither establishes the intentions of every participant.

Write a testable rule, select data containing the required inputs, include costs and evaluate later periods without reusing them for parameter selection. Start with the quant beginner guide, then the futures backtesting guide.

Confirm the current terms for your exact account and use. Market-data access, manual execution, automation and copying require separate checks. Senzoukria supports analysis and optional armed Rithmic automation; it is not globally read-only.
