Pinning is coincidence. Reuters just a story written about a strategist who said that we'd pin SPY at 110 due to OI. If it's an edge, please let us know a week in advance so we can exploit it.
Quote from volente_00:
gaps at 1069 and 1101 cash
don't see us going over 1130 cash before moving down
Quote from volente_00:
As long as you can handle the heat to 1069 cash when they do decide to fill the gap
We are on the high end of the range here and spy options indicate a move back down to fill those gaps.
I'd put a top on cash at 1140, with 1130 being more likely before this happens.
Quote from atticus:
Think of looking at OI as volume in profile (market profile). The atm strikes will be the high volume as we approach expiration. It's a convergence on price and volume. It's often self fulfilling, but of no predictive value. We'll have to agree to disagree.
Quote from volente_00:
I don't follow market profile.
How can you say no predictive powers when I posted the range spy options gave me on August 2 and 3 were 1069 to 1130-1140 and since then we traded 1129 to 1063?
I will say that my reads on spy are only correct about 80% of the time.
You may call this just coincidence or luck but I have profited very well from using spy options to gauge market ranges.
Another thing I find interesting is when it does close with a high strike ITM, it often reverts back to it the following monday. My hunch is this has to to with assignment.

Quote from atticus:
No, it really isn't. It was, like 20 years ago. The volume in the options is so small relative to the volume in the underlying.
