Data Provider

Market data is licensed from AxiomX LLC d/b/a Theta Data under a commercial agreement. Flowstradamus LLC presents visualizations and aggregations derived from this data.

Underlying Markets

US equity data originates from the consolidated equity feeds (CTA/UTP SIP and Nasdaq Basic). US options data originates from the Options Price Reporting Authority (OPRA). All trademarks and data rights remain the property of the respective exchanges and reporting authorities.

Delay

All data presented to subscribers is delayed by at least 15 minutes. Flowstradamus does not display real-time quotations.

End-User Data Restrictions

Use of the data shown through the service is subject to end-user restrictions that pass through from our data provider and the exchanges. See End-User Data Restrictions and Terms of Service §8.

Derived & Aggregated Visualizations

Flowstradamus displays transformed, aggregated visualizations — such as net premium pressure, sector bias, and flow concentration — rather than raw bid/ask/last quotations. These are computed from the licensed data and are intended for educational observation.

Methodology

Flow events are aggregated by symbol, option type, and sector and ranked by notional premium. Cumulative pressure reflects running call-minus-put premium across the observed session. No proprietary scoring is used to imply a recommended action. See the Methodology page for the full description of what the platform measures and how.

Accuracy

Data is provided "as is." Flowstradamus LLC does not guarantee its accuracy, completeness, or timeliness. See Terms of Service.
