I can tell you that about 20,300 July 19 $20 calls traded on April 24 between $2.10 and $2.34. That accounts for most of the current open interest in that strike which is the only call strike at that expiration with such a large open interest. I don’t know if those were buy to open or sell to open contracts that traded on 4-24. Today About 5500 contracts at that same stroke or trade between $.84 and $1.12. I won’t know until tomorrow if they were opening or closing trades.

On April 26 10,000 contracts of the July 19 $18 put were traded between $1.90 and $2.08. Those contracts account for most of the current open interest in that strike, and again I don’t know if they were buy to open or sell to open.
