Some things that appealed to me are that they sell themselves as a high touch firm and they have pretty solid capital, well above the requirements. I have looked at a broad array of firms and am just looking to understand the pros and cons of each. While $6 is high, my strategies would be holding positions for many days, in some cases weeks. So it is not really that big a deal, yet I still find it somewhat questionable and was wondering perhaps they are a much more professional or reliable outfit and that is what the extra cost was justified by. Your post probably explains it, since they are based on an old model of high commissions, and if they are high touch then they probably expect more money for their time spent with customers.
As for the quality of their accounting systems, well that is a problem. I appreciate the feedback.
