buy followed by an immediate sell ..., page-2

sorry accidentally sent the post early ...

I'm wondering if it is normal to follow-up each buy with a sell and how it can happen that they get the exact same time stamp!?!?

A couple examples of what I'm talking about:
Course Of Sales Last 20 Trades|All Trades
Time Price ($) Volume Value ($) Condition
12:05:15 PM 0.086 24,481 2,105.366
12:05:15 PM 0.087 90,000 7,830.000

11:57:31 AM 0.086 21,192 1,822.512
11:57:31 AM 0.087 115,000 10,005.000
