Charts suggest a new upside target for the dollar-yen after fresh stimulus measures from the Bank of Japan (BOJ) pushed the pair to seven-year highs in early November.

The BOJ surprised markets with second round of monetary easing on October 31, pledging to step up purchases of exchange-traded funds and real estate investment trusts, extend the duration of its portfolio of Japanese government bonds, and increase the pace at which it expands its monetary base.

The BOJ's move accelerated the dollar-yen's breakout above the peak resistance level near 106. The behavior of this fast rally is constrained by the pattern of trading band activity that has dominated the market since June 2013.

Starting June 2013, the dollar-yen traded within a broad sideways pattern between 97 and 106. A support and resistance level developed in the middle of that trading band near 102.

The width of this trading band allows us to set upside targets for the current rally breakout.

The first projection target for the breakout above 106 is set at 110. This was achieved and the market retreated and tested 106 as a support level. The rebound from 106 pushed above 110 and rapidly reached the next trading band projection target near 114.50. Traders will now watch for consolidation around this level and a potential retreat and retest of 110 as a support level.

A successful breakout above 114.50 has an upside target near 119. This is a major long-term resistance level. It dominated market behavior from 2001 to 2003 and again from 2005 to 2007. The market oscillated around the 119 level so there is a high probability that a significant consolidation pattern will again develop in this area.
