Quote from cdcaveman:
What is that volume thing!
As I understand, it's volume profile (Volume traded at specific price within defined period of time). I use other volume indicators, but following his chart
The highest volume was traded within 571-604. During this time the biggest number of shares was bought/sold. Respectfully, those who bought during that period, are still comfortable, as they are still in profit and we are not going to see any panic selling until AAPL hit this range. However should AAPL drop in that range and should these trader to start panic....
