A $50 expense transaction will have amount = -50, transaction_type = STANDARD, and it will decrease the balance of an asset account but increase the balance of a debt account. A $200 transfer from account A to account B will have two transactions: one with amount = -200, transaction_type = STANDARD for account A, and another with amount = 200, transaction_type = STANDARD for account B. An opening balance transaction will have transaction_type = OPENING_BALANCE, and its amount can be positive or negative depending on the initial balance of the account.
