I think it is a good idea. Who would draft the opening salvo? Here is a little starting "contribution". I think that the letter should include a statement such as "... in the interest of providing better market transparency and a level the playing field between the investing public on one side and market makers on the Nasdaq and the Specialists on the NYSE on the other side, it would be useful that privileged information about trading in securities be made public at once. For instance, at this point in time, the public has no information on the short position in any given security for more than 45 days after that information is available to those "insiders". Technologically, there is no logical reason such information not be made public at once, or at least on a daily basis. The only reason one could fathom is giving a privileged advantage to said Market makers and Specialists. Removing this preferred treatment in availability of information will go a long way in restoring the public trust in the securities trading system in this country...."
