Would appreciate hearing about the low latency trading groups in Chicago. A friend left GETCO and wants to trade fixed income. He needs to set up an arrangement with a prop group or a low latency brokerage group with high connectivity to various exchanges (i.e. typical CME fills around 30ms or under). He's told me about the following: GETCO Breakwater (merger with Peak6 dead?) Sun Trading Speed Trading He mentioned there might be some former Hull guys around running smaller, under the radar shops. For you NYC-area guys, prop firms in Chicago aren't pure arcades or strictly places with a 50%/50% or 80%/20% split and a desk fee. Would appreciate any posts about firms you might know about. I'm also interested in knowing more about these types of firms. Thx.
