You beat me to it, just didn't realize. Go back and look at your FAS/FAZ post from 3/16 in daily market talk, they're there. I've looked at Aroons and Aroon Oscillators before but couldn't make head nor tail out of them just staring at them, kinda like Ichimokus which are coming fairly natural to me at this point, tho fine points still to be learned.
When in doubt, always read the instructions (they are there for Aroons and Aroon Oscillators in Stock Charts, I just never dug in on them til this week when I read some article that used them in the analysis-finally making sense to me, similar to ADX but not the same. Look at the Aroons same time as you look at ADX, comparison provides additional information.
