Investopedia: Best Short Term Stock Screener, 2024
Real Stock Race replay, recorded.
The short answer
Use Massive if you need the raw US stock tape (trades, quotes, bars, filings) by API.
Use Trade Ideas if you need finished trading decisions — Streaming Alerts, Top Lists, OddsMaker, Holly.
Use both when Massive owns the pipe and Trade Ideas owns the intelligence built on top of it.
Trade Ideas publishes this page and makes one of the two tools. Massive (formerly Polygon.io) is a market-data company, not a scanner.
Two jobs
What each one does
Massive (formerly Polygon.io) sells raw US stock data to developers and AI builders: trades and quotes history, minute bars, basic indicators, financials, SEC filings and news — via API, live stream, bulk download, and AI-agent hooks. It does not ship a stock screener, live alerts, or built-in backtesting. Customers build those on top of the feed.
Trade Ideas ships the finished trading layer: Streaming Alerts, hundreds of filters, Top Lists (Screeners), OddsMaker, Holly, TImo, SIM and Brokerage Plus. Top Lists re-qualify which stocks every 15 seconds; ranking, sorting and data update in real time.
Key point
We do not invent Massive plan prices on this page. Check Massive’s own site for current API pricing.

The database of meaning
Why isn’t Trade Ideas just another data API?
One screen, several windows, all on the same live data.
Our edge is the database, not the tape. We keep every alert that fired, every filter value for every stock at every moment, and what happened next. Nobody can buy that history back as a raw feed.
Key point
Massive is excellent at delivering the raw US stock tape. Trade Ideas turns market events into a searchable, replayable history of meaning — which alerts fired, which filter values were true, and how price moved after. That is what OddsMaker and Holly sit on.
Together
Can I use Trade Ideas and Massive together?
Yes. Buy from Massive what Trade Ideas doesn’t keep as a product — for example deep tick history or filings you need by API. Sell or stream Trade Ideas alert and filter history as intelligence on top of that feed, including one AI connection that offers Trade Ideas signals plus Massive data.
Developers / AI builders: Massive for the tape; Trade Ideas when you need finished alerts, filters and signal history.
Trading desks: Keep Massive where you already build on the feed; add Trade Ideas for Streaming Alerts, Top Lists, OddsMaker and Holly during the session.
Partnership, not replacement: This page is not an “alternatives” pitch. We do not publish /alternatives/massive/.
