Was this a scalping strategy or something? Back when I worked at the CBOT (upstairs, not downstairs), I'd talk with the floor traders about this sort of thing. Since everyone basically knew everyone, it was very obvious who the good traders and bad traders were (and who the FBI agents pretending to be traders were!), and a lot of times when you were bored and didn't know what to do, you'd just fade the losers and make a few ticks. But no one actually went after those bad traders to "get" them, as in pushing the whole market around just to make sure one guy takes a loss. It was more like taking advantage of a really accurate contrary indicator.
I like Al a lot, and respect his work, but in this case, it sounds like he might have read one too many of the Wall Street conspiracy books that are so popular these days. As long as you're not risking your whole account on every trade or something stupid, then just run the account up until you're so huge that you can't help but get noticed. Then, if you ever get taken out by a Flash Boy

, you'll have taken one losing trade, but will be so far ahead at that point it won't even matter.
I'm sure the reference he was making was to the "Flash Boys" book, which was about getting poor slippage due to HFT shennanigans in the stock market. So rather than buying at 100.00, some sneaky bot sits there and bids the market up a penny right before your order gets in, they sell to you at an inflated price (100.01), and then cash out immediately after back at 100.00. Not exactly the same thing as someone targeting you personally though, unless that someone can recognize your trade and take action in the matter of microseconds. And if you are trading with one penny stops, then yeah, you're probably going to get taken out in the end, but it won't be anything personal - it will just be market noise that does it.
