Why can I not transfer out my positions or withdraw funds from my account after my ACATS transfer has been received?

The rejection of your order with a notification about funds not being fully available for withdrawal may be due to the fact that funds are not fully settled to be transferred from your IBKR cash account into PAXOS account, our provider for Cryptocurrencies liquidity…

The Withdrawal Hold Period is 3 business days (you may withdraw funds after 3 business days). A wire cannot be internally transferred during the 3 days hold period.

TRANSFER POSITIONS INTERNALLY

If you executed a trade but you selected the wrong account by mistake, you can either trade out of the position or request an internal transfer to your other IBKR account. Please note, you will only have the option in Client Portal to internally transfer positions if the account holder information is identical and the receiving account has approved trading permissions for the position. If the choice to internally transfer positions is not available, than those criteria were not met. For example, you would not be eligible to internally transfer positions from a taxable Margin account to a non-taxable IRA account. …

Although during the withdrawal hold period it is possible to execute currency conversions, you are not allowed to withdraw the newly converted funds before the withdrawal hold period expires.

An amount equivalent to the original deposit can not be withdrawn or transferred internally until the hold period expires…
