One of the biggest misconceptions about markets is that the most recent trade price is the current value. But that's not actually true – it's approximately true in heavily traded m…

"Practical" is right – a seemingly "theoretical" exploit turns out to have serious practical implications. This is a really well-written article with lots of examples. Excellent wo…
