That's almost impossible with noisy indicators, and almost all
indicators have noise because the underlying data used to create
them is noisy. You might have good luck using indicators having a
long lookback, though.
For smooth functions, finding the inflection is easy. You have an
inflection point if an increasing slope becomes a decreasing slope,
or if a decreasing slope becomes an increasing slope. If foo is the
return value of your function then
if foo[3]-foo[2] > foo[2]-foo[1] and foo[1]-foo[0] > foo[2]-foo[1]
then you have an inflection point where the slope has started to
increase.
Exchange '>' with '<' to test where a slope has started to decrease.
