To see at which prices most of the trading happened, ask LargeTrader A.I.: show me the volume profile of AAPL. It asks which period to calculate it over: for example, the last month.
In the answer you'll find the main values, and on the right, the chart with the volume profile. The horizontal bars on the right show how much volume traded at each price level: the green part is the volume of the up moves, the red part the volume of the down moves. The orange line is the POC, the point of control: the price where the most trading took place in the period. The two dashed lines, VAH and VAL, mark the edges of the value area: the price band where seventy percent of the volume traded. At the top, the label shows the period of the calculation: here, from October fourteenth to November tenth.
When the price leaves the value area, it moves into a zone with little trading in the period: useful information for reading the levels.
