<\/a>\nThe obvious question: Who are these traders who respond to spoofing orders by placing their own orders? Why is it a crucial goal of law and public policy to prevent Mr. Sarao from plucking their pockets? Is “herding trader” or “momentum trader” or “badly programmed high-speed trading program” or just simple “moron in the market” now a protected minority?<\/p>\n
Why is Mr. Sarao being prosecuted and not all the people who wrote badly programmed algorithms that were so easily spoofed? If this caused the flash crash (how, not explained in the article) are they not equally at fault?<\/p>\n

A fact which will probably not enter at Mr. Sarao’s trial (he doesn’t seem to have billions for a settlement) and will give him little comfort in jail.<\/p>\n
And maybe, just maybe, there is something more coherent here than the Journal lets on. I’ll keep reading hoping to find it and welcome comments who can.<\/p>\n

John Cochrane writes in his Grumpy Economist blog:\u00a0Just when you thought financial regulation couldn’t get more expansive and incoherent, our Justice Department comes in to defend morons’ right to herd.\u00a0 Mr.\u00a0Navinder Singh Sarao is now under arrest, fighting extradition to … Continue reading
