Greetings, New trader here, and new to the site. I'm considering moving trading funds from an account with Merrill to Interactive Brokers. I recently had funds frozen in a Rogers commodities index account as a result of Refco bankruptcy, and still do not know when, or if, I will recover, or in what proportion. So, in the event of widespread economic collapse, how does one protect their wealth? How does one asses the relative strength and viability of an individual brokerage? As a general observation I find this topic overlooked, but that seems dangerous to me.
