Guess the OP-EX Pin????

I just looked at the SPY options chain and the pin that looked like $120 has shifted, here are the calls and puts.

Calls

There's decent open Interest at $121.00 and $122.00


PUTS

Here the Open Interest is $120 and $122. So the two most likely areas would be $120 and $122. I'm guessing around $120 with some volatile chop.
