As I understand it, with Aroons,It's like watching the tic by tic evaluating the percentage of change, in time, occurring between high trades (buys)and low trades (sells).
Thus if 4 asks trade, then 2 minutes later 4 bids trade, then 5 asks and 10 bids with 5 minutes between. It calculates the 2 minute and 5 minute differences over a period of time. referencing the number of buys/sells and finds the given interest level of buyers and seller over time.
AS this interest changes the up line (ask) and the down line (bid) reflects the change to generate a trending indicator.
At any rate I'm only into these arron for 2 weeks and still learning myself, but that's how I understand it to work. Not using levels of PPs change, kind of cuts out the MM playing with it. Running PPs up 6 cents or down 6 cents means nothing. How many buy & sell vs how often, shows a sideway perspective rather that an up & down one.
Why I think it works well with manipulated stocks.
Success!
