    Guides/9. Intel: borrow, dilution and catalysts

    Guide 9.4

    Why is it moving? Catalyst grading

    Intermediate, 7 min read. Checked with Scalpel 1.12.8 on October 15, 2026.

    In short

    Scalpel grades every headline from the news providers on your IBKR account by kind (FDA, trial data, deal, earnings, M&A, hype, offering and more) and strength, from None to Explosive. The strongest recent one becomes a chip such as FDA 4m: green for strong news, blue for decent, grey for weak, and red for an offering, which is never graded as good news. A keyword grader answers instantly; with an OpenAI key, an AI grade replaces it within seconds.

    "Why is it moving?" is the first question on any runner, and the answer decides a lot. FDA approval on a $20M company can carry it all day; a conference attendance press release usually cannot; an offering means the company is selling to the people buying the spike. Scalpel answers it on the scan row and the desk, so you do not have to open a news window while the stock moves.

    Before you start

    • Intel on (guide 9.1), with News in its status lines showing your providers.
    • Optional: an OpenAI key, for AI grading.

    Where the headlines come from

    Scalpel uses the news providers your IBKR account already has through the API, such as Dow Jones and Briefing.com. There is no separate paid news feed. When it starts watching a stock, it loads the last News history days of headlines (3 by default), then streams new ones live. The same story arriving on several Dow Jones feeds within 10 minutes is merged into one, and market columns and roundups are never graded as a catalyst.

    Kinds and strength

    Each headline gets a kind, shown on the chip:

    ChipKind
    FDAAn FDA or other regulatory decision, designation or clearance
    Trial dataClinical trial results or data
    DealA contract, order, partnership, licence or collaboration
    EarningsFinancial results or guidance
    M&AA merger, acquisition, buyout or tender offer
    HypeA pivot into a hot theme: AI, crypto treasury, quantum, drones, nuclear, rare earths
    UplistA move up to a major exchange
    OfferingRaising money by selling stock, warrants or convertibles, or registering an offering
    Reverse splitA reverse stock split
    DelistingA listing deficiency, a delisting notice, or regaining compliance
    AnalystAn analyst rating or price target
    LegalLawsuits, settlements, patents
    Fluff PRA press release with no real content, such as a conference appearance
    NewsAnything else

    And a strength, judged for a low-float momentum stock, not a large cap:

    StrengthGradeMeaning
    Explosive4Company-changing: FDA approval, a buyout, a contract bigger than the company, a hot-theme pivot
    Strong3Important: positive trial data, a large contract, a strategic deal
    Moderate2Real but ordinary: a meaningful contract, solid results, trial progress
    Weak1Minor: a small order, a conference, a routine update
    None0Nothing price-moving

    An offering is always red, whatever else the headline says, and never graded above weak: "Acme Prices $10 Million Offering Following FDA Approval" is offering news, not FDA news.

    Note

    Grades run from 0 to 4 in fractions. The strength word in the hover card's list is the grade rounded, while the chip colour uses the exact grade: green from 3, blue from 2, grey below. So a 2.5 reads Strong in the list with a blue chip, and a 1.5 reads Moderate with a grey one.

    The chip and its card

    The chip shows the lead catalyst: the strongest graded headline from the last 24 hours, newest on a tie. An offering headline always leads, so it can never hide behind good news. Automatic filing notices never lead. The chip's label is the kind and the headline's age: FDA 4m, Deal 2h, Fluff PR 16h.

    Hover it for the verdict and the recent headlines, each with its age, strength and kind:

    How the grading works

    The keyword grader runs on every headline the moment it arrives, and stands alone without an OpenAI key. It checks rules in order, dilution first, so an offering word wins over everything else, and shrinking or ending an offering program is correctly not dilution. A concrete dollar figure on a deal or result adds half a point.

    HeadlineKeyword grade
    Acme Receives FDA Approval for Lead CandidateFDA, Explosive, green
    Acme Reports Positive Topline Phase 2 ResultsTrial data, Strong, green
    Acme Signs $40 Million Supply Agreement With Major RetailerDeal, reads Strong, blue chip (2.5)
    Acme Launches Bitcoin Treasury StrategyHype, blue chip (2.5)
    Acme to Present at Healthcare ConferenceFluff PR, Weak, grey
    Acme Announces Pricing of $5 Million Registered Direct OfferingOffering, red

    The AI grader, with an OpenAI key and Grade headlines on, sends the headline (and the start of the article, when IBKR supplies it within a few seconds) with the ticker, price, change and market cap. It answers four questions: the kind, the strength against the company's size (a deal worth more than the market cap is huge for a micro cap), whether it raises money, and whether it is new information rather than a recap. Its grade replaces the keyword grade when it lands, usually within a few seconds; if it times out, the keyword grade stays. Of the history loaded at start, the 8 most recent headlines from the last 24 hours per stock are AI-graded.

    Alerts

    ABCD FDA: Abcd Receives FDA Approval for Lead Candidate
    CDEF offering: Cdef Announces Pricing of $6 Million Registered Direct Offering
    EFGH filed 424B5: Selling stock off its shelf
    Intel toasts: a strong catalyst (blue), an offering on a stock you watch (amber), and a financing filing on a stock you hold (red). Demo data.
    • A strong live catalyst: graded Strong or Explosive (3 and up), judged new, and under 15 minutes old, on a stock intel is watching. An info toast and a sound, reading for example ABCD FDA: Abcd Receives FDA Approval for Lead Candidate. Turn these off with Strong catalyst alerts in Settings > Intel if they are too chatty.
    • An offering headline always alerts and cannot be switched off: a red toast and a spoken exit warning on a stock you hold, an amber toast on one you only watch.

    Click a toast to load its stock onto a desk. More in guide 10.2.

    Timing: news vs EDGAR

    The news and the filings race each other. Dow Jones posts a line for each 8-K within about a minute of EDGAR. A company's press release usually hits the wires before the matching filing, and an offering priced in the evening usually reaches you as a headline hours before its 424B prospectus appears the next morning. Scalpel reads both (guide 9.2), so whichever arrives first sets the chip.

    Paid news terminals will be ahead on some headlines. The point here is having the news, the dilution read and the borrow read on the desk where you trade, graded the same way every time.

    Careful

    A green chip is not a reason to buy on its own. Strong news on a company that is selling stock, or news that broke three hours ago and has already been traded, can fail fast. Small-cap momentum trading carries a significant risk of loss.

    What can go wrong

    • No catalyst chips anywhere. Check the News line in Settings > Intel. "News: waiting for IBKR" means no providers are available to the API on your account.
    • A moving stock has no chip. No headline on file in the last 24 hours, the only headlines are columns or filing notices, or the stock is past the 40 symbols intel follows.
    • The grade looks wrong. Keyword grading is blunt. The AI grade is better at context; check OpenAI: on in the status lines.

    Questions

    Where does Scalpel get its news?
    From the news providers on your Interactive Brokers account, through TWS. Scalpel does not add or require any paid news feed.
    Why is an offering never good news in Scalpel?
    An offering means the company is selling new stock, often to the buyers of the spike. Both graders put dilution first, and the AI grade of an offering is capped at weak.
    Do I need an OpenAI key for catalyst grading?
    No. The keyword grader grades every headline without one. The key adds AI grading, which judges strength against the company's size and spots recaps.
    Why does the chip say Fluff PR?
    The headline is a press release with no material content, such as a conference appearance or a letter to shareholders. The move is mostly momentum or hype.
    How old can the catalyst on the chip be?
    Up to 24 hours. The age is on the chip, for example Deal 2h. Older headlines stay in the hover card's list but no longer lead.
