The trading pit that electronic trading replaced had far more potential information leakage. You can see which broker is demanding what. Also in order to get the "direct feed" you had to be an exchange member, or rent a seat from

Also because it is not front running. Front running has a technical and legal definition that someone looking at a public feed does not meet.

If teaching were as competitive as market making major cities might graduate more than half their students from high school while simultaneously driving down costs. Non profit is not a badge of honor.

So you were involved in illegal activity? Maybe you should call the SEC and pickup the whistleblower percentage?
