About a quarter of my clients have their accts at AMP, the rest are at Advantage, Crossland, and Dorman. Both of my accts(my money) are split between AMP(personal acct ) and Advantage(corp acct). *** Thought you might want to get a glimpse of this below... seems there are more brokers/clearing agents that have failed to properly segregate funds. This rampant negligence is a ticking time bomb if the CFTC doesn't get more aggressive on increasing the frequency of audits on these companies. http://www.reuters.com/article/2012/03/13/us-mbfclearing-cftc-lawsuit-idUSBRE82C16W20120313
