I see the logic sort of hit here. I am with an nasd firm now so I have not kept current in the requirements demanded by other exchanges. But, to trade your own dough your license does not have to necessarily be current. Hence the reason why people in my old office were "grandfathered in". They were "professionals" because they had passed the series 7 exam. They did not have a current license, yet the exchange allowed them to trade. In fact at these other exhcanges since the series 7 goes stale ; every trader, after 2 years, is sort of grandfathered, dont you think.
