Not yet sure who it was but there was a very serious seller in the cable yesterday starting at 1.5000 and selling in size every few pips. The market was bulled up on the pound in early London and was intent on driving EUR/GBP lower but this seller repelled all advances. I’m also hearing that there are plentiful stops above 1.5050 which suggests to me that lots of traders and hedge funds know about this order and have sold already with stops above.
