OVER 200 SELLERS POPPED UP JUST ABOVE CURRENT PRICE
THEN DISAPPEARED. DIDN'T CATCH THE PRICE, BUT IT WAS
AROUND 979 OR JUST LOWER.
These large blocks of bids and asks seem to show up then disappear.
They must be getting handed off to a floor trader who deals in large
blocks of contracts, although sometimes the number just sits there
on my bid/ask window.
