I MANAGE A PORTFOLIO

How your portfolio is built, and how it holds up in hypothetical scenarios

Portfolio Research reads your positions as a report: drawdown, allocation by position and sector, risk contribution and correlations, each chart with its as-of date and window. Try it first on the Sample portfolio, with no one’s data, and run the Stress Lab’s hypothetical shocks on it.

The market’s structure, session by session

Changed Together lists tickers whose data layers changed in the same week, listed and not ranked. Structural Anomalies shows measurements far from a ticker’s own history, with percentile and n. Event Study measures how much tickers moved around earnings dates and SEC filings, compared with a market model and with random dates of the same tickers — and says plainly when a kind of event looks no different from a random day. The Market Regime Atlas labels Calm, Normal or Stressed volatility at each close and never revises it, and the Market Time Machine shows a past date with only what was public by its close.

Your trades, with the market they happened in

Import a CSV or Excel export from your broker, or log trades by hand. Each trade keeps the conditions at entry: gamma regime, market events and the macro calendar. The Research Lab groups and compares your own fills by those conditions. It describes your trades; it never grades them.

Real data, not a mockup.

Estimated gamma exposure across hypothetical spot prices, computed from the options chain. Open interest is OCC data from two trading sessions earlier, so it trails the price; the note below the chart says how it is calculated and how old the data is.

HOW THIS IS CALCULATED
Estimated Gamma Exposure. Gamma is not vendor data: it is computed with Black-Scholes from an implied volatility back-solved from the bid-ask mid. Open interest is published by OCC after settlement and reaches us two sessions later (T-2 sessions). Contracts expiring on the current New York date are not included during their own session: days to expiration is counted in whole calendar days, so a same-day expiration counts as zero. The sign of each strike follows the usual published convention: call gamma counts as positive and put gamma as negative, which assumes dealers are long calls and short puts. It is an assumption, not an observed position. Not investment advice.
This is SPY, refreshed during the session. The dashboard covers the tickers in our gamma universe.

Measured. Dated. Connected.

01

Measured in-house or taken from the filing

Gamma is estimated with Black-Scholes from the options chain, not bought from a vendor. Short interest comes from FINRA, fails-to-deliver from the SEC, insider trades from Form 4 filings, and volume is compared with each ticker’s own baseline.

02

Every figure carries its date

Lagged data says how old it is: options open interest arrives after OCC settlement, and short interest follows FINRA’s twice-monthly schedule. Estimates carry their measured error, and scenarios are labeled hypothetical.

03

Connected to your trades

Market events and the financial calendar sit next to the structure, and the journal keeps all of it at every entry.

Before you start

What is TradeAI News?

A research workspace for US equities in seven suites: estimated gamma and options structure, market events and unusual volume, insider and offering filings, short interest, portfolio research, market research tools and a journal that keeps the market conditions of every trade. We measure significance and magnitude, never direction.

What does the free Pro trial include?

Every Pro feature for 21 days: the Gamma Suite, the Context Journal and Research Lab, Portfolio Research, the Research Desk, What Changed and the Intelligence suite. No card is required, and there is one trial per person.

What happens when the trial ends?

Your account moves to the Free plan. Nothing is charged, because no card was taken. You can choose a plan at any time, before or after the trial ends. Your journal trades stay in your account: on Free you can view, export or delete them.

Do you tell me what to trade?

No. There are no recommendations and no price predictions. The platform describes what is in place — positioning, filings, volume, short interest, portfolio structure — and the decision stays yours. Stress Lab scenarios are hypothetical, and every estimate is shown with its error.

How current is the data?

Each figure shows its as-of date. Options open interest arrives after OCC publishes it at settlement, and the methodology note on each chart says how many sessions behind it is. Short interest follows FINRA’s twice-monthly schedule, and insider trades appear once the Form 4 is filed with the SEC.
