Dollar up before FOMC minutes; some wary on QE size

The dollar was sold sharply as market players factored in the prospect of more quantitative easing after the Fed's rate-setting meeting on Sep. 21, when the central bank said it stood ready to provide more support for the economy and expressed concern about low inflation. more
