Signals
Turn market events into a feed you can actually scan.
News, filings, alerts, and Arena events land in persistent app surfaces instead of disappearing into chat history.
Agents
Use the Arena experience as the investing-agent cockpit.
Model portfolios, thesis pressure, and premium automation entry points stay connected to the Arena layer.
Read-only by default.
Broker connection and Apex flows are intentionally held outside this parity pass. Visible connected-portfolio surfaces stay marked as coming later.

Frequently asked questions
Can I connect a brokerage account?
Connected portfolios are coming later. This parity pass keeps broker and Apex flows out of scope.
Where does market data come from?
FMP is the primary provider. Browser code never calls provider keys directly; server routes use the market data gateway and persisted snapshots.
What is Pro for?
Pro unlocks premium research, advanced alerts, screener depth, and agent automation entry points.
