[amibroker] simplest way to detect a reversal of direction in an indicator

["Dave Merrill" <dmerrill@xxxxxxx>]

what's the simplest way to detect a change of direction in some indicator by
more than a certain amount? it's easy to see on a chart, you just look for
peaks, and find the places where the indicator has moved the required amount
from there.

I have a working version that requires crossing an absolute level first,
before the change in direction will be honored. that's doable because you
can use HighestSince(AbsoluteLevelCrossed), but I can't see how to build a
similar thing without that absolute level crossover. what you really mean is
HighestSince(CrossoverInTheOppositeDirection), but that makes the level your
looking for dependant on the crossovers that came before it.

you could step through the indicator array one bar at a time to do this, but
it seems like there's got to be a better way.

any ideas? is my question clear?

thanks,

Dave Merrill
