As you can see, I'm in a short. My take profit is the support, and lines on my chart below. The SNB will intervene yes, however I think that'll be as the EURCHF approaches the 1.20 floor. I'm favouring the GBP in strength and have the bias that the EUR/GBP will drop.

There is definitely room for price to drop to this level before the SNB step in.
