Useless. Figures double count the seeling of QQQ May 22 puts and the buying of April QQQ 22 puts.
One is a bullish bet the other a bearish bet. On the whole the transaction is a total wash. Total OI did not change one iota. Lately more and more of these seem to be occuring.
PC ratio and especially PC moving averages are meaningless after such nonsesne for quite some time IMO.
