Liquidity Taker

@BadAlgo what evidence do you have that its one algo? Looks more like two of them best in booking eachother to me

@nanexllc what exchange are you looking at? CME did not gaurantee order of packet publication in 2008 #HFT but hey lets call it cheating..

@apppro1 why is the sec clueless?

@nanexllc who do you think refills the book when somebody is trading size? I will give you a hint, its not retail. #HFT

@nanexllc market participants have different needs, its common sense

@nanexllc looks like someone needed to trade and #HFT did its job, thank god they were ready to keep the markets in line #STOCKS

@nanexllc if #HFT was not providing liquidity this would have went much farther
