What you get

A measurement layer, not a crystal ball

01 — The Dataset
178K scored headlines and counting
Every headline scored by FinBERT — a BERT model fine-tuned on financial text, not generic sentiment. Tagged to a ticker, timestamped, deduplicated by URL, drawn from 12,500+ distinct sources since 2019. Roughly 6,500 new ones a week.
02 — Strategy Testing
Backtest it yourself
Don't take our word for it — run the strategy against real history. Tune direction, hold period, transaction costs, stop-loss/take-profit and position size, then see the actual trade log, equity curve, regime breakdown and walk-forward stability. No black box.
03 — Signal Analysis
Correlation, measured not claimed
Pearson r, p-value and a 95% confidence interval on sentiment shifts vs next-day returns, per ticker. Most tickers come back inconclusive — and we show you that, because a sentiment tool that always finds signal is lying to you.
04 — API Access
Developer-ready endpoints
REST API with sentiment scores, price history and correlation data. 15,000 calls/mo included with Pro. 200,000 with Data. Integrate into your own systems or bots.
05 — AI-Native
Built for Claude, Cursor & agents
Every endpoint is also exposed as an MCP server — wire SentimentFX straight into Claude Code, Claude.ai, Cursor or any MCP-speaking tool as a native tool, no custom integration required.
06 — Price History
OHLCV in the same query
395,000 hourly bars across all 42 tickers back to 2023, and daily candles to 2019 — stored alongside the sentiment, on the same timeline, so you never have to join two vendors' clocks together.
07 — Coverage
Five asset classes, one schema
Crypto, FX, stocks, ETFs and commodities behind identical endpoints. Headlines refresh every 15 minutes; prices and correlation hourly.
08 — Dashboard
Terminal-style UI
Bloomberg-inspired interface. Candlestick and sentiment-vs-price charts (1H/4H/1D), signal strength ratings, and a live headline feed — all in one view.
09 — Alerts & Brief
Optional email digests
Set sentiment thresholds per ticker and get told when they're crossed. Alerts are screened against a backtest first, though on most tickers that screen finds nothing worth sending — by design. Plus a daily morning brief, with every past edition in a public archive.
📊
What this does — and what it doesn't
We've tested whether our sentiment score predicts next-day price four separate ways: daily, intraday, across five alternative formulations of the signal, and as an overlay on breakout and moving-average strategies. It doesn't, reliably, on most tickers. We ship the backtester so you can confirm that for yourself rather than take our word for it.

So we don't sell forecasts. What we sell is the measurement layer: a large, clean, queryable record of how financial media talked about 42 assets, scored consistently by one model, sitting next to the price data on the same timeline. What you build on top of that is yours.

How it works

STEP 01
News scraping
Every 15 minutes our pipeline pulls fresh headlines for 42 tickers across crypto, FX, stocks, ETFs and commodities, then deduplicates them by URL.
STEP 02
FinBERT scoring
Each new headline passes through FinBERT. We take the positive minus negative probability and present it on a 0–100 scale, where 50 is neutral.
STEP 03
Correlation analysis
We measure whether sentiment shifts historically correlate with next-day returns — and report the p-value and confidence interval alongside, including when the answer is "no relationship found".
STEP 04
Delivery
Everything lands in the dashboard, the REST API and the MCP server simultaneously. Same numbers, three surfaces, no black boxes.
