Adding to last idea, where we may have seen this pattern before on 2014/04/15 @ 2100 PST. Back then it was 200 and 400 MAs. This time, last night GBPJPY hit off of 400MA, this morning hitting off of 200 and 100 MAs.
Aiming for 173 and beyond. TP stop placed under ST MAs, waiting for that GBP 1st GDP to come out tonight.
