Strange for an options expiration day. Just saying.
Volume down too - didn't know this was a 3 day weekend.
Gotta make sure that those 2150 puts are barely out of the money. Close will be $21.50, within a nickle.
Its amazing as to how this all works.
I wonder if one can program HFT to a specific end or expectation.
My original thinking was that High Frequency Trading just took advantage of inconsistencies in minute to minute trading.
Any comments or thoughts will be read with interest. thanks.
