As an example of why Nanex is worth listening to, here is an article [1] describing how Nanex claimed Monday's ISM manufacturing data was leaked 15 milliseconds early, leading ultimately to an admission by Reuters that it caused the leak. Eric Hunsander, a software developer at Nanex, went so far as to hint to Reuters that they should check their NTP settings since a drift of 15 milliseconds is allowed by default [2]. Eric is very interesting to follow on Twitter [3]. He highlights mysterious HFT related events on a daily basis. My only complaint is that his articles and charts, in particular, are very difficult to interpret. As an outsider to the HFT industry, I don't know where to find the resources to learn enough to interpret most of Eric's insights.
