Transactions that are green signify an addition to your account. This could include deposits or transfers to the account (including payments). When you see a minus in front of the transaction, this means that an amount was deducted from your account. Purchases made with the account/card and withdrawals would all be considered a deduction from the account.
If you feel that your transactions are being marked incorrectly, please first check your statement with your corresponding bank to see if it matches. If it does not, send us a message with details, and we’ll pass it along to our engineering team to investigate!
