i like to have that bigger in my TWS:

That are all outstanding options. As every option represents 100 shares you can say "The Market(tm)" has to pay 4.320.000$ to those options-buyers for EVERY DOLLAR over $800 for the 800-calls alone!
Thus it makes sense for sellers to short for some days (current borrow-rate is 0.26% - so basically free) to get the price below & buy back on monday.
A second problem: If you have to deliver on that call you actually have to own those shares! If you have a short-position then maybe the person lending you those shares wants them back - yielding higher rates and other nasties.
The puts are exactly the opposite.
If you calculate the integral over everything "The Market(tm)" has to pay you get those nice diagrams with red "cost of puts" bars left & green "cost of calls" bars right & max-pain in the middle.
But Max-Pain is just an average for "The Market(tm)" and does not include individual institutions.. Gordon may hold onto his $20-puts & skew the max-pain in that way. That is why some of us look at the chart and identify "line of defenses" for those big players. In this case: 700, 730, 750, 800 calls. On the other hand we have also a high number of puts at 800 - where other institutions may be interested in getting the price higher. So the 700s basically cancel each other out, everything below 700 is out of reach & because of the high 800-spike over 850 should be unrealistic.
the 800 puts nearly cancel the 730 calls - so the line should be somewhere between 750-800 according to this theory (more towards 750).
This theory is ONLY valid if
- manipulation is easy (e.g. low volume)
- no breaking news
- macro-assist in the right direction (i.e. macro up/down-movements in the "right" direction get enhanced)
- no crash or similar marketwide things.
At least that is my view of it
hope that helps & clears things a bit up.
