After you initiate a transfer-out request, your Tradesk account will be frozen immediately from trading, depositing, or withdrawing as these transactions may disrupt the transfer process.
For a partial transfer out, your account will be unrestricted once the transfer is completed.
For a full transfer out, your Tradesk account will be automatically closed after the ACAT transfer is completed if a closure was requested at the receiving firm. Any new funds or shares in your Tradesk account will be swept to the other brokerage account.
