Has the signal ever "inverted." For example trading with cycle periods,
every so often (perhaps 1 in 5 times) the cycle "inverts". An expected low becomes
a top or vice versa, and the present trend extends into the new inverted top/bottom.
There is no way to recognize it except by hindsight after we've gone through
it. From that point forward the cycle may have shifted 1/2 cycle or sometimes
reverts back to its prior periodicity. In any case, this is an example of what
I am referring to. Has your system ever "inverted" this way, so that the top
we're expecting in this time range doesn't occur?
