I think that Le Pen is a couple of rungs too far up the extreme ladder for the French to vote for her but they could protest vote her in the 1st round, and blow her out in the second. It's all so very close though so on balance I'm going with a market favourable result and EURUSD opening up at 1.0820.
Guessing a price is one thing, trading is another, so I think I'm going to cover some of my EURUSD longs with some OTM puts around 1.0550.
