What the crowd's watching, and what dealers have to do about it

How to read it

Bullish % is the StockTwits crowd — retail sentiment, straight from the source, with the 7-day change so you can see which way it's moving.

The flip is the price where net dealer gamma crosses zero. Above it dealers hedge by damping moves — they sell strength and buy weakness. Below it that inverts and they amplify: selling into weakness, which is what turns a dip into a slide.

The call wall is the strike holding the most dealer gamma above spot. On the way up it acts as a magnet, because dealers buy stock as price rises toward it. Once price is through it, that mechanical bid is spent — which is why "past wall" plus an excited crowd is the most common trap on this board.
