RexUnda
Signal Intelligence for Retail Traders

Signals institutions pay $30,000+/year to see.
Priced for retail traders.

RexUnda surfaces high-impact trading signals from underground sources — EDGAR filings, foreign-language chatter, supply chain disruptions — scores them for confidence, and shows you exactly which of your positions are affected. Before mainstream news reacts.

Process

How RexUnda works

Three steps from underground signal to portfolio clarity.

01

We crawl what institutions read

EDGAR 8-K filings, Benzinga Pro alerts, foreign-language social signals, supply chain disruption data. Sources your broker doesn't have.

02

We score it with AI

GPT-4o extracts the signal, assigns a confidence score, and estimates the expected move direction and magnitude.

03

You see what matters to you

Paste your holdings. RexUnda flags which signals affect your positions and by how much.

A whisper in the data. A storm in the market.

FAQ

Questions, answered.

RexUnda doesn't publish news — it crawls the underground sources institutions use to get ahead of news. EDGAR 8-K filings, earnings whispers, Reddit sentiment shifts. The signal arrives before the headline, not after.
New signals hit Alpha Access tier first. After 4 hours they roll down to free tier. You get the full signal while free users see a delayed version.
RexUnda only aggregates publicly available information. We don't use non-public data or insider information. Every signal source is public and free to access.
