The volatility, given the lack of information on overall majority, was quite curious. So I was top and bottom slicing it to get a gross traded total on the market. The seat total on the spread betting markets was creeping up all night, so I lumped all the profit on a conservative majority. When the exit poll was announced, my work was done. So it would have been all or nothing for me. But it seemed fairly clear that, if you ignored the fuss on social media, a clear majority was going to happen.
Dutched the turnout market aiming for slightly higher turnout, so that wasn't a terrible idea. But turnout was lower by about 1%, so the importance of the election didn't seem to shift that as much as I thought.
