A portfolio account owner holds the flexibility to deposit any whitelisted asset accepted by the risk engine at any time. However, during withdrawals, the risk engine must ensure that the remaining capital can cover the maintenance margin and the debt associated with opened positions collateralized by the same portfolio.
