* Informational only; not investment advice.
Explore a price move, a technical setup, or a market comparison. Tape B brings the evidence into conversation—and helps you distinguish what is observed, what is calculated, and what is interpretation.
Know where a number comes from, what a model assumes, and how far the evidence supports a conclusion.
Read-only market research. No trade execution or personalized investment advice.
Cloud Offerings

How Tape B knows
A market observation, a calculation, and an interpretation carry different kinds of authority. Tape B's method keeps those distinctions in view as the conversation develops.
Observed
Prices, candles, and quoted sizes from the connected source, with observation time and available delay and coverage information.
Source · Time · Coverage
Calculated
Indicators and modeled scenarios derived from stated inputs and assumptions. A model value stays distinct from a market quote.
Inputs · Method · Assumptions
Interpreted
A reading of the observations and calculations, expressed with the uncertainty they support. Conflicting or missing evidence limits the conclusion.
Reasoning · Uncertainty · Limits
A framework is a perspective. Source-specific ideas retain their scope. An interpretation does not become a universal rule or a recommendation to trade.
A clearer question makes the evidence easier to read. The timeframe shapes which observations and calculations answer the question.
Daily prices are observations. Moving averages are calculations. What they suggest about a trend is interpretation.
How it works
Begin with the instrument, timeframe, and market question you want to investigate.
Tape B retrieves the available market data, identifies its source and observation time, and reports relevant coverage limitations.
Explore calculations and supported visualizations, keeping model assumptions and interpretation distinct from the underlying observations.
Follow up to revisit the question with fresh observations.
Status and technical information
The public Modeler and invited web beta do not connect to brokerage accounts or retrieve account balances, positions, or orders. Neither places, modifies, or cancels trades.
Access and data status. Tape B Intelligence requires an active invitation and provider entitlements. Availability, timing, and fields depend on the connected feed; observations and calculated or model-generated explanations may be delayed, incomplete, unavailable, or incorrect. Authentication does not grant exchange permissions or redistribution rights.
Private beta / 2027
Tape B's current invitation-only web beta provides public-equity analysis* and illustrative option modeling. Recruitment for planned brokerage integrations targets January 2027, subject to development, provider agreements, and applicable approvals. The beta is free and read-only. New waitlist submissions are temporarily paused. Recruitment updates. Existing tester? Enter the beta.
