Earlier this year I tried to open a second IRA account and transfer some of my IRA funds from IB to another broker via a partial ACAT (for only about 20% of the account). IB refused to send the funds via ACAT and I eventually just withdrew the funds and deposited them in the new IRA. However, now I would like to move more money but can't use the withdrawal method as it has not been 365 days since I last did it. Has anyone had any success using ACAT to withdraw funds from IB successfully? Aren't there laws or rules about this?
