The Top Mover Score (TMS) is the core of the system. Every event receives a score from 0 to 100 calculated by the 6-layer engine before it reaches you.
Not a generic sentiment score. It is the result of comparing the event against 2M+ historical situations, measuring propagation velocity across sources, analyzing market microstructure, verifying cross-asset correlation, and determining the closest historical pattern. Only events that clear relevance thresholds are delivered as alerts.
Every event passes through 6 independent subsystems. The final score is a weighted combination of all 6. No single layer decides the outcome on its own.
Historical similarity (35%): Pattern matching against thousands of prior events. Velocity (15%): Cross-source propagation speed. Microstructure (20%): Order flow, spreads, and options activity. Cross-asset (10%): Sector and ETF confirmation. Timing: Historical reaction window for this catalyst type. Pattern recognition (15%): Match against 28 catalogued event archetypes.
The system aggregates data from 26 simultaneous sources. Each is weighted by its historical record of significant detected events.
Regulatory: SEC EDGAR, FDA, NYSE/NASDAQ Halts. News: Benzinga, GlobeNewswire, PRNewswire, Reuters, BioSpace. Financial: Finnhub, Alpha Vantage, FMP, Yahoo Finance. Market: Alpaca SIP (level-2), Unusual Whales, Quiver Quant. Social: Twitter/X, StockTwits, Seeking Alpha. Specialized: ClinicalTrials, OpenBB, Earnings Calendar.
Every headline is processed by a financial NLP model trained specifically on financial text and earnings language.
The sentiment model was trained on millions of financial news articles and earnings reports — not generic text. Returns a sentiment score from 0 to 100 (50 = neutral). Scores ≥60 → Positive. Scores ≤40 → Negative. This score is combined with TMS to contextualize the event without replacing the score.
The system classifies every event into 40+ catalyst types so you can filter exactly what interests you.
Types include: FDA_APPROVAL, CLINICAL_TRIAL, EARNINGS_BEAT, EARNINGS_MISS, M&A, MERGER, ACQUISITION, FILING, COMPLIANCE, EQUITY_FINANCING, REGULATORY, FRAUD, SHORT_SQUEEZE, INVESTIGATIVE, AI_PARTNERSHIP, SUPPLY_CHAIN, GOVERNMENT_CONTRACT, ANALYST_UPGRADE, ANALYST_DOWNGRADE, OPTIONS, and more. Each catalyst has a historical magnitude profile.
Access every detected event from the browser. Live news feed, full event detail view, and integrated Alpaca price chart.
The dashboard includes: live news feed with catalyst filtering, top movers view with TMS scores, per-event detail page with 5-min price chart, sentiment indicators and AI scoring breakdown. Auto-refreshes every 15 seconds with no page reload required.
Certain event types trigger fast-track mode: normal queues are bypassed and the alert is sent immediately, regardless of score.
Fast-track activates for: FDA approvals (all types), NYSE/NASDAQ trading halts, M&A deals and announced acquisitions, earnings releases outside regular hours, definitive SEC material filings (DEF14A, SC 13D). In fast-track mode the system prioritizes speed over complete analysis — you receive the alert while the engine finishes scoring.
Trading halted pending material news. Scoring in progress.
Every event stores the price return at 1h, 4h, and 1 day from the event. This enables real-world outcome tracking.
Returns are updated automatically by comparing the detection price against subsequent prices. Available in the signal dashboard and exportable via API. With this history you can study which catalyst types and TMS score ranges historically preceded the largest price moves — magnitude of movement, not direction — to inform your own independent research.
Access every detected event directly from your trading system via REST API. Endpoints for recent events, detail by ID, and historical data.
