OK I for one am getting tired of missing quick moves when those fake ARCA B/A's are out there. just now i missed a quick couple of bucks because of a fake ARCA offer, while my order was out in limbo and i was waiting for a cancel while the slightly higher offers got taken out...
this is BULLSHIT
please, IB, disable ARCA
