1/ Four key moments from the ARG-ESP World Cup finals, starting with Spain's goal at the 106' mark:
Argentina-win book (crashed from 40% --> 12%) - 25k shares resting within 5c when the ball crossed the line - First cancel occurred 70ms before the ball crossed, removing liquidity at the point of foot contact - 80% of all cancels landed within 262ms of each other, 95% of size removed from the book before takers landed
Spain-win book (ran from 60% --> 88%) - 15k shares resting within 5c when the ball crossed the line - Only 15% of cancels landed in time - A 10k limit order from one maker failed to remove in time and was executed at 60.3c, accounting for the majority of the Spain-book losses associated with the goal
