We have a Bearish Bat developing  on the GBPUSD 4 hour timeframe

Harmonic Pattern GBPUSD Bearish Bat

Has a bit to do yet to get to its predicted D point , but if it does it could be a good one to take back down to around the 1.57 area.

One to watch for the longer term.

If price breaks 88.6 retracement of XA  to the downside before it gets to D then the pattern is invalid.
