200 day MA and 38.2% retracement

Fundamentally, industrial production surprised to the upside, but that came later.
Technically, the price action supported a move higher with the pair moving outside the box that has confined the pair over the last 7-8 trading days. The pair based against the "remembered area" at the 1.52386–43 level and that was a bullish clue.
