Forex technical analysis: GBPJPY has a rare down day. Is it telling us something?

15 of 18 days higher. Not today…
By my count the GBPJPY has been higher 15 of the last 18 trading days. That has taken the price from a low of 135.57 to the high yesterday of 148.10.  The high price yesterday got close (for this pair at least) to the December high of 148.447.  Today we are seeing a pretty good down day. The pair is currently down about 125 pips. At the lows, the price was down about 170 pips.
