Pick how you want your money split across investments. We keep it there, even after prices move it out of shape.
Already using it?
Decide what share of your money goes into each stock or fund.
Whatever goes up becomes a bigger share than you meant it to be.
On whatever schedule you set, trades pull it back to your target.
One holding or 250 — your mix can be as simple or as detailed as you want.
Group holdings into a slice, and slices into slices — several levels deep if you need it.
Paper and live Alpaca accounts both work today. We're working on adding more brokerages next.
Every rebalance starts as a preview — the exact trades it would make, with nothing submitted yet.
Every rebalance waits for your explicit approval — nothing trades until you say so. Want it fully hands-off instead? Turning on auto-rebalance is a clear, one-time authorization, not a hidden setting.
Pick a mix, see how it would actually have done — no account, nothing saved.
