The U.S dollar gained ground Wednesday against the EUR and the British  pound, after strong data on orders for new U.S.-made durable goods and  new home sales comforted expectations of an improvement in the economy.  The greenback traded higher after the durable-goods orders report said  orders for July rose by 4.9%, the largest increase in 2 years.  Investors will be watching for the new U.S. jobs report today before  making significant moves.
