Why do TWS Line Charts print at odd increments?

Discussion in 'Trading Software' started by achilles28, Apr 16, 2013.

  1. For instance, TWS line charts (tick charts) for ES will show trades occurring at odd levels, outside of regulated quarter point increments - for example 0.34, 0.62, or 0.81. etc.

    How is this possible?

    Same with ym.....mostly odd prints are half a point (0.5), or one quarter point (0.25).

    I don't get it. Is this meant to throw tick traders off, or?
