When users deposit certain stablecoins to FTX US, they are automatically traded for USD. We do not show the trade from the stablecoin to USD in CoinTracker, so when they spend the USD for an asset, we show that they still hold the stablecoin.

The same problem exists for Withdrawals. If a user withdraws a stablecoin, FTX US automatically swaps their USD for the stablecoin. This results in a negative balance error in CoinTracker because we do not show the swap.

If you wish to work around this issue, you can manually add/modify transactions to account for the automatic swaps. Instructions for manually editing trades can be found on our support site. Please be aware that manual changes to transactions typically have to be removed when a fix is applied.
