It means: ..."they're able to identify your desire to buy shares in Microsoft and buy 'em in front of you and sell 'em back to you at a higher price...... It all happens in infinitesimally small periods of time..... There's speed advantage that the faster traders have is milliseconds, some of it is fractions of milliseconds..... But it''s enough for them to identify what you're gonna do and do it before you do it at your expense........ So it drives the price up, and in turn you pay a higher price....of which they gain by selling it to you.

Too add, GS, UBS, MS, Pershing(largerst US security clearing firm ) and others have orders executed out of Jersey City, Hoboken or Weehaken becausec of greater and more capable it and fiber optics. A half a second can be a difference maker by 1-1.5 percent return on large volume trading.. A good spread is usually between 70 to 160 basis points. High doped routing can add 20 basis points. That’s huge in relevancy.

Technology is a difference maker. The old NY building don’t have the tech like Jersey city due to age.
