Haim Bodek, one of the key figures of Dark Pools, is profiled today in a page one The Wall Street Journal article (written by me and my colleague, Jenny Strasburg). The story dives deeper into Bodek’s odyssey at the high-frequency firm he helped run, Trading Machines, and reveals more about his role in a sweeping SEC probe into ties between stock exchanges and some computer-driven funds.

The story also reveals more of the inner workings of an “order type” that Bodek learned about at Trading Machines, one he came to believe gave HFTs the ability to step in front of other investors’ orders. It’s name: Hide Not Slide, provided by Direct Edge. (For more on Direct Edge’s order types, read the following.)

For anyone interested, here’s Bodek’s web site.
