Interestingly, on a daily cart it shows the Open to be outside the High-Low spread of the day...

There are several ticks at the open of each of those days that are out of the range. (See Omega.15 picture)

For example, on 9/7 there are two trades shown at 9:30AM ($11.97 and $11/98)

They also show up in the Time & Sales Window (See Omega.16 picture).

The market Depth chart shows several orders way outside the range, no doubt trying to pick off market orders... (See Omega.17 picture)
