Coinbase Advanced Trade limit orders will reduce the asset balance of the synced Coinbase wallet while waiting to be executed. No transaction will appear unless the trade is completed.
This means that while the asset is held for the limit order it will reduce the portfolio balance on the main dashboard and wallet page.
We should look into whether we want this to be the case as it may cause confusion for users expecting their balance to be the same while waiting for the limit order to be executed.
