An IRA is a tax deferred investment product for US citizens and legal residents. Transferring the IRA to another US based brokerage firm is initiated at the receiving firm.
Keep in mind that if you would like to transfer assets from Firstrade to another US based financial institution via ACAT, Apex Clearing will charge a partial ACAT transfer fee of $55 or a full account ACAT transfer fee of $75.
Partial Transfers will require a remaining account value of $555 (with at least $55 in cash balance). Otherwise, a full Transfer should be requested.
