"Therefore, when the information was officially released in Washington, New York should see it 2 milliseconds later, and Chicago should see it 7 milliseconds later."
At which millisecond was the information "officially released"? Which of Bernanke's phonemes were decisive? Or do we know to the millisecond when the Fed's site was updated?
I suppose the coincidence between Chicago and New York is still a thing. Everyone receiving the leak agreed to fire at a particular time, and nobody jumped the gun?
