Three things worth checking first

Partnership

Alpaca Securities LLC

How our clearing and custody arrangement works, what it covers and what changed for clients. Read the announcement.

Compliance

Who holds your assets

Registrations, SIPC and Excess SIPC protection, and who is responsible for each part of the process. Security & compliance.

Platform

What you can invest in

US stocks and ETFs, index exposure, fractional orders from $1, three strategy profiles and the four-step onboarding path. See the platform.

Why This Structure

A software layer that cannot touch your money

Your account is at the broker

Your securities account is opened with Alpaca Securities LLC, member FINRA/SIPC, and carried there on a fully disclosed basis. You log in with the broker, and you can withdraw or transfer the account elsewhere at any time — without asking us.

Protection in two layers

SIPC protection up to $500,000 per account (including $250,000 for cash claims), plus Excess SIPC insurance carried by Alpaca and placed with Lloyds of London, up to $75,000,000 for securities and $75,000,000 for cash per client.

Signals with a stated process

The signal engine combines a macro overlay with behavioural-finance inputs contributed under our advisory mandate. We publish what the mandate covers — and what it does not.

Investor protection & risk

Every protection described on this page has published limits: SIPC responds to broker failure, not to market losses. Investing involves risk, including loss of principal — the full risk disclosure sets out what that means in practice.

How It Works

From sign-up to a funded account in four steps

You open one account, with one broker-dealer, and the platform manages the workflow around it. There is no second set of books and no internal wallet to top up.
