Aren't Virtu and Getco (KCG) now the same thing?How do you compete with the code writers at Getco and Virtu?
Knight + Getco = KCG
Virtu + KCG = Getco.
Also Virtu is not known for really advanced coding, just very efficient at what it does. Vinnie was never a quant. Just ask his ex-partners, some of whom post occasionaly here.
