Max pain is the closing price at which option holders, as a group, would collect the least. Think of it as the price where the most tickets would expire worthless.
For Oct 13, max pain is $772, $3.71 below today's price. If the stock closed there on expiry day, option holders would collect about $6M in total, less than at any other strike. The theory is that dealer hedging pulls the price toward it near expiry. In practice it is a loose tendency, not a forecast.
This curve shows how likely each closing price is, based on today's at-the-money IV. Taller means more likely. The shaded band holds the middle 68% of outcomes.
There is no at-the-money IV for this expiry, so the curve can't be drawn.
