Forex futures market positioning data as of the close of the markets on  Tuesday, January 10, 2017
The largest change came in the the JPY where shorts in that currency were trimmed by 7K. The position is still somewhat elevated historically at short 80K (see chart above). That net position also represents the largest open position of the major currencies.  Nevertheless, the decline is reflective of some profit taking near the highs of the USDJPY.
