While self - publishing has enabled genuine talents like Amanda Hocking to rise to the top, the general lack of editing and selection means that there's a much worse noise - to - signal ratio among self - published works than among professionally published writing.
However, signals on the lower time frames are naturally less reliable than signals on the daily chart because the daily chart works to «smooth» out the noise and randomness that can occur on time frames below it, thus showing you a more accurate picture of the market.
For a variety of reasons, it is difficult to distinguish signal from noise over periods of less than a year.

It's also clear that the data contains both noise and signal, so the autocorrelation of the data is greater than that of the noise.

This is what the discussion should focus on — the signal rather than the noise.
that some level of statistical significance can be achieved for periods shorter than 30 years, but not 15 years because fluctuations in things like solar + ocean - atmosphere heat exchange make it hard to say with high confidence what's signal and what's noise.
