Max Pain & Gamma Walls: Options Expiry Price Magnets

Max pain is the strike price at which the largest total value of outstanding options (both puts and calls) would expire worthless - in other words, the price point that causes maximum financial pain to options buyers as a group. There's a long-standing (and debated) theory that price tends to drift toward max pain as expiry approaches, since options sellers (who are often better-capitalized) have an incentive to hedge in ways that pull price there. Gamma walls are price levels where market makers hold heavy options exposure that requires them to buy or sell the underlying to stay hedged as price moves. An upside gamma wall can act as resistance (hedging flow sells into rallies toward it); a downside gamma wall can act as support (hedging flow buys into drops toward it) - though once a wall is broken with force, the same hedging flow can accelerate the move instead of cushioning it. BTCWEAPON.COM shows max pain and both gamma walls together with how far they sit from the current price and how many days remain to that expiry, since their pull is strongest close to expiration and weaker weeks out.
