has taken place numerous times just before close and I believe it's always the same two, Union and Interactive where they trade a penny up but it's always for 10 shares perhaps sometimes 50. It's inconsequential to the sp but at a glance looks like a positive for the sp. It has happened today and Interactive only traded those 10 shares today. Smells to me. I've heard of houses sending signals this way and I can't imagine any other value to this trade. Any takers on an explanation? Not too long ago it was taking place most every day.
