There are quite a lot of stops building below 1.5120 and again below 1.5100 in EUR/CHF. Dealers often try to take advantage of thin twilight-zone markets to try and trigger such stops. The expectation in the market is that the SNB or BIS will appear on the bid but I have no information at present as to what level they are sitting on.
I’m also hearing of a decent sized sell order in the NZD/USD between .7075/.7100.
