Quote from Lawrence Chan:
The key to whether right below 860 or 847 is the combined size and puke point of the long positions built from the breakout crowd at the top, and the dip buying crowd from friday.
I see 1 mil contracts up there, 75% open interest.
So most overnight contracts are net long from WAY ABOVE.
That does not include the underlying stocks.
Edit: should be 50% open interest.
