I would imagine the algos will hammer ES very quickly (up or down), a lot faster than a unexpected UK vote. They will be all over the news feeds for exit polls and things like that. I bet will be a nightmare to delta hedge through thatThe ES will already be open. Similar to Brexit, I think a binary event like an election can be managed through the night. The ES didn't gap down--it was a drop over a few hours until it hit limit. If Trump is elected, I would imagine the drop will be of a similar character.
