Your title ' Betting on Brexit Event' doesn't sound encouraging. I'd prefer title like 'Trading the Brexit Event'. Well. Past few days, GBPUSD, UK bonds and Germany bonds are moving alot, and its day range have been very healthy. So these are the great financial instruments for trading over the next few days/weeks.
As it stands right now the probability of an extension of any length is high. No deal which in this case would be the EU rejecting the UK's ask for an extension isn't likely. Brexit will look softer not harder in any case going forward. May chose country over party and rightly so. I still have puts on cable because the default scenario priced in is an extension and the markets are a little too complacent that there isn't an off chance that perhaps Macron will veto. I don't see a massive rally in cable, all these theatrics are just kicking the can down the road. Am up slightly on deltas so will probably scratch the trade on break even.
