What this is

☁️ Cloud broker — Alpaca exposes a public REST API, so this runs directly in the Starchild container, no local gateway needed. US equities and ETFs.

Paper and live are fully separated: different key pairs, different hosts (

paper-api.alpaca.markets

vs

api.alpaca.markets

). A paper key physically cannot touch the live account. Live order placement additionally requires the

--confirm-live

flag.

Get your API keys

Sign up at alpaca.markets (US brokerage; paper trading is free and needs no funding).
Paper keys: log in → switch to Paper Trading (toggle top-left) → Home → "API Keys" panel → Generate New Keys. Copy the Key ID and Secret Key (secret shown once).
Live keys (optional, real money): switch to Live Trading → same API Keys panel → generate. These are a different pair from paper.
Market data: the free IEX feed works out of the box. SIP (full-market) needs a paid data subscription.

Configure (.env)

Gotchas

```
status
```
is the health check — it reports SDK install state, key presence, and pings the account. Run it first.
Free IEX data can be sparse/delayed off-hours; use
```
sip
```
only if the account has the paid feed.
Live trading is real money. The
```
--confirm-live
```
gate is intentional; never auto-add it.
