Primary-cycle windows, then stochastic confirmation

The archive workflow names a roughly 17-week primary cycle, opens a four-week window around expected troughs and crests, and then looks for stochastic or intermarket nonconfirmation. Editorial reading: treat the cycle as a calendar first, and use the oscillator only to decide whether a turn is forming.

  • Name a roughly 17-week primary cycle first and treat its four-week window as a calendar around expected troughs and crests, not as an automatic trade.
  • Inside that swing, label three six-week phases, two nine-week phases, or a mix of both, and time those nested phases on daily index charts.
  • In the S&P futures sample, bullish stochastic divergence appeared at 25 of 44 primary bottoms, and bearish oscillator or intermarket nonconfirmation appeared at most documented primary tops, but not at every turn.
  • Editorial reading: the cycle supplies the when; use stochastic disagreement, and multiple-time-frame alignment, only as the whether.

Name the primary cycle first

The study treats a roughly 17-week primary cycle, with a four-week timing window, as the trader's comfort-zone cycle. That rhythm links shorter nested phases to a longer 50-week cycle. Expected troughs and crests are first marked as calendar windows on that primary rhythm.

Editorial reading: treat the named dominant cycle as a calendar window first. The window tells you when a turn is due. It does not, by itself, tell you whether to act.

Time the nested phases

Inside that primary cycle the author looks for either three six-week phases, two nine-week phases, or a mix of both. Troughs and crests are labelled so each subcycle phase can be timed on daily index charts. The shorter rhythm is a timing tool within the larger swing, not a substitute for the primary window.

Wait for the shorter chart to agree

Cycle work is paired with multiple-time-frame alignment. A shorter interval is used for entry only after it starts moving with the trend of the next longer interval.

What the historical sample recorded

In the S&P futures sample, bullish stochastic divergence appeared at 25 of 44 primary bottoms. That setup is price making a new primary-cycle low while the stochastic oscillator does not.

Bearish oscillator divergence at primary-cycle crests was more frequent than the bullish counterpart at troughs. It occurred in 33 of 44 S&P futures crests.

Across 45 crest cases, 41 showed either intermarket bearish divergence or oscillator bearish divergence. Intermarket divergence is a nonconfirmation between two related markets, such as S&P futures and the Dow Jones Industrial Average, at a candidate cycle turning point. At least one of those nonconfirmations was present at most documented primary tops.

S&P 500 futures primary-cycle lengths, 1982–1997

Each point is one trough-to-trough primary cycle on S&P 500 futures, taken from the article’s dated 1982–97 list. A trader should see a calendar that clusters near 17 weeks, with most turns inside a 13–21 week window and the longest readings often landing on four-year-cycle dates.

Parentheses in the source list are weeks from the prior primary trough, not months. Asterisked cycles coincided with a four-year cycle. The author counts 36 of 44 cases (81.8%) in the 13–21 week interval; six of the eight distortions lasted 23–28 weeks. The first printed date, August 1982, is the start of cycle 1 and has no length of its own.

How the pieces work together

Editorial reading: keep the jobs separate. The primary cycle supplies the when. The stochastic oscillator supplies the whether, and only when price and the oscillator disagree inside the open window. Intermarket nonconfirmation can play the same confirmation role at a candidate crest. Even then, wait until the shorter chart begins to move with the next longer chart.
