Hi Craig
Its a function of the volume on both sides of the equation.
Take HDR @ the moment
On the sell side ya got 2@50c v 4250
2@51 v 170393
and on the other side ya got 1@51 v1000
and 17@50 v 317715
Match price is 51 with surplus V 164643 on the Ask
AOT gives ya all the match price onscreen - pretty handy
