The euro may extend its rally from a two-month low against the yen, according to Gaitame.com Research Institute Ltd., citing trading patterns. The 17-nation currency formed three-consecutive white bars on its candlestick chart and exceeded the colored bar formed on April 13, signaling “the euro is bottoming out,� said Takuya Kawabata, a researcher at Tokyo-based Gaitame.com. White bars show that the currency’s closing price is higher than the opening level, while the colored ones indicate the opposite. The euro may be headed for a high reached on Feb. 27, a most that would form a so-called head-and-shoulders pattern with a March 21 high being the head, said Kawabata, whose company is a unit of Japan’s largest foreign-exchange margin firm. A head- and-shoulders pattern appears when a currency makes three consecutive peaks, with the middle the highest. The euro was little changed 107.25 yen as of 10:45 a.m. in Tokyo after touching 104.63 on April 16, the lowest since Feb. 20. The common currency reached 109.93 on Feb. 27 and advanced to as high as 111.44 on March 21, a level unseen since October.
