Alpaca Broker API — Journals

Journals move value between two accounts within your own Alpaca omnibus — typically between a pre-funded firm/sweep account and a user account. They are the engine behind "instant funding," cashback, and share rewards. They never touch the outside banking world (that's alpaca-broker-funding-transfers).
