False. If there were no risk, it would be illegal, and your'e still tossing out that incorrect term without explanation as to what you mean by it since you clearly can't mean the illegal practice of front-running that we've already agreed they aren't doing.

Not relevant.

False.
> And not sure how what I'm claiming is wrong.
Because it's simply not true. Once again, you've ignored my question, you still cant' explain what HFT's are doing wrong, my guess is because you don't actually know what you're criticizing so you toss out flash boy hyperbole like front-running without actually being able to explain what you mean.
> This has been the entire reason why IEX exists.
The IEX exists as a reaction to traders who were displaced by HFT creating a desire for an exchange that doesn't allow it; it in no way proves HFT is doing anything wrong. It's nothing more than marketing capitalizing on fear to establish a new exchange, perfectly legal, but it doesn't make the irrational fear against HFT legitimate.
