The Dollar was up again most major rivals Monday on expectations of continuing improvement in the U.S economy ahead of this week's data release. The Dollar rose to a six week high versus the Yen and traded near a three and a half month high against the EUR. The Dollar Index, which tracks the greenback against a trade-weighted basket of currencies, was at 78.059 from 77.758.

The Dollar has been gaining in recent sessions, as concerns over Greece's government deficit have weighed on the EUR as well as upbeat economic data from the U.S which is prompting investors to reassess when the Federal Reserve will begin tightening the U.S. monetary policy.

While a slow news day is expected today ahead of the Holliday weekend, the release of the Existing Home Sales at 15:00 GMT is expected to provide some volatility to the Dollar, with better then expected results intensifying the Dollar's recent upward trend.
