Flash crash trader jumps into currency market when others flee

New York

ISAAC Lieberman loves a good flash crash.

There is nothing nefarious afoot here, to be clear. It is just that at a time when many currency trading firms do not know what to do when extreme price fluctuations hit, Mr Lieberman has brought together a bunch of military and technology gurus to form a firm - Aston Capital Management - that is designed to thrive at those moments. When others shut down, it gears up.
