TBG was questioning "Block Trade" not an AON order
Of course, anyone can buy / sell 10,000 - 20,000 - 30,000 - 40,000 - 50,000 - etc. shares at Any price (given volume). Surely you've done such X0,000 AON orders on many stocks over the years, as I have. - However, an AON Order was not what TBG was trying to discuss, in his posting regarding a "Block Order".
