    Need help to see if someone have answer for this:

    asking is 3.9
    bid is 3.7
    Trade 12:00:01pm 1000s @ 3.7
    immediately a same quantity trade 12:00:01pm 1000s @ 3.8
    Trade 12:30:01pm 2000s @ 3.7
    immediately a same quantity trade 12:30:01pm 2000s @ 3.6
    etc etc...

    duplicate same quantity and same trading time but different

    I heard of same price (double print), same qty and same time due to the computer
    system program or maker matching delay. Never heard of different price.

    Thank You
