Glossary

All 581 terms
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.
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.
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.

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.
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.
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.
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.
Liquidity wall
A concentration of displayed resting size at one price in the order book. Its disappearance can be an execution or a cancellation; the two are only distinguishable with the corresponding event data.
Gamma exposure on futures
A gamma exposure level modelled on an options underlying such as SPX or NDX and then transposed onto ES or NQ. The transposition depends on the basis at a stated time and on the futures tick, and stays conditional on the options snapshot it came from.
Depth of market software
Software that displays resting order-book size as a price ladder and, where the account permits it, routes orders from that ladder. What it can show is bounded by the depth the connection delivers, aggregated by price or order by order.

v0.81.0Latest

Talk to Sen with Jarvis, ThetaData without a console, Big Trades for Spot & Perp, GEX levels on every chart.

  • Talk to Sen with Jarvis. A voice bubble on every screen. Click to talk, hold a key (F8), or go hands-free. Sen can read its answers aloud. The microphone never opens without your gesture.
  • ThetaData without a console. GEX and Option Flow start their own hidden ThetaData terminal and stop it when you close the app. Java 21 installs in one click.
  • Big Trades for Spot & Perp. A big-trades indicator built for Binance Spot, Binance Perp and Bybit. Set a density of bubbles per 100 candles, or your own dollar threshold, remembered per pair.
  • GEX levels on every chart. Call wall, zero gamma and put wall from any source, ThetaData included, on the right underlying: QQQ for an NQ or MNQ chart. A badge says why when no line is drawn.

Questions

The same answers search engines read on this page.

What is orderflow trading?
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.
Where should a beginner start?
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.
What is the difference between options flow and GEX?
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.
How do I start quantitative trading research?
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.
Is orderflow software allowed on a funded account?
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 manual Rithmic orders; it is not globally read-only.
