Jean- Claude Trichet, European Central Bank President, said that excess of volatility in exchange rates is bad for global economic stability. Mr. Trichet agrees with U.S. economic policy makers about the importance of a strong U.S. dollar; usually, his announcements are reliable in Forex Trading.

The greenback rose above its four-week moving average last week, signaling the U.S. currency will make further headway, said Masashi Hashimoto, a senior analyst in Tokyo at the unit of Japan’s biggest publicly traded bank. Momentum indicators, such as the stochastic oscillator, also show buy signals, he said.

The U.S. dollar may extend its advance against Japanese yen to reach the strongest level in a month. The USDJPY closed at 90.542 last Monday; some traders predict an uptrend in some days.
