The original stated size was huge both in terms of the float and in terms of typical bets made by the firm.
The revised figure makes more sense.
But its also interesting to note that the company apparently has never had to do a revision before. So its kind of ironic that this was the trade they got wrong.
Plus, I thought the screenshot from the Bloomberg screen was somehow an actual fill or something, not just what is reported, but I have no idea how this all works. If that screen is simply a manual entry, that doesn't inspire a lot of confidence in me about all the positions listed.
