Actually, skinners, I'm not a big fan of the 'Us and Them' conspiracy theory, and I very much doubt that any more than a handful of people were privy to a sneak preview of the release.
It only takes the first player who has seen the news to react and take the offer and put a bid in its place causing the price to break from its range, and that will trigger 100's (if not 1,000's) of algos into following the price action. Those algos won't have necessarily seen (or interpreted) the data as they will just be programmed to act like sheep and chase the price. It's almost certain that they will also be programmed to close out immediately the army of retail punters try to get on board and provide some liquidity for the algos to sell into. As per the Nanex data, this was done and dusted in a flash.
So, no great conspiracy theory from me, just an observation that the HFT algos won, and the retail punter who takes 650ms to press his mouse button (and 11 minutes to find the mouse beforehand) will have lost. I don't even think there was anything complex about the algorithms used - it is simply a case of the firms involved having super-duper hi-tech connections into the liquidity pool to ensure they're the first to reach the offer.
