1. First x is a markdown bar lots of showing selling.
2. Second x, vol obviously from apple announcement day but still, a strong market could have be used for lots of distribution.
3. Red Bar: market reaches high of high day, rejected and closes on lower. Also of note are the narrowing spreads over the previous three days on average , showing kinda lack of interest in following prices up after what could be seen as heavy selling
$100 price level usually is very psychological number that leads to selling by good traders in response to poor traders buying the market. Apple looks like it's gone through a bull campaign to top out on announcement day
