October 1987 cycle overlay and the loss-trap

After a September low and an early-October freeze on a held loss, a day of analog work produced an accidental cycle-overlay of 1920s Dow and 1980s Major Market Index charts. Editorial reading: that overlay is a forecast only when equivalent-time alignment, a written break from the loss-trap, and size rules under quote-latency are tested as one procedure.

  • After the August 1987 peak, a stated view looked for a fall-equinox low, and a low printed on September 22.
  • A 100-point drop then left a held loss and a loss-trap freeze until prior trades were flattened and a day was reserved for the 1929 analog.
  • Gear-locking-cycles and several equivalent-time candidates preceded an accidental cycle-overlay that was read as peak-in, then used to list Dow paths near 1750 and 1623.
  • Editorial view: listed levels and index-put timing do not complete the forecast; equivalent-time, the written break from freeze, and size rules under quote-latency have to be tested as one procedure.

A classroom for an operational analog

The paragraphs that follow restate one 1987 workflow: a stated equinox low, a freeze on a held loss, a day of analog work, a cycle-overlay, listed Dow levels, index puts, and a stand-down. Any lesson about what makes the overlay a forecast is marked as editorial.

A stated low after the August peak

After the August 1987 peak, a stated view looked for a low around the fall equinox. A low printed on September 22.

The loss-trap

In early October a 100-point drop produced a held loss and a freeze driven by incomplete information plus concern about family capital. Editorial label: that stance is a loss-trap, a held losing stance in which fear of being wrong and fear of harming others block exit and fresh analysis.

Gear-locking-cycles and equivalent-time

Prior trades were flattened and a day was set aside to re-examine a 1929 analog and a 60-year cycle that a caller had placed in 1989. The reply was that the cycles would be similar rather than identical.

Astrophysical cycles from each era were screened for gear-locking-cycles, cycle components from two eras treated as meshed so that phase in one period can be mapped onto phase in another. Separate 1980s Major Market Index and 1920s Dow charts were searched for an equivalent-time match among several candidate alignments. Equivalent-time is a chosen alignment that places two historical price paths on a shared cycle clock for comparison.

The accidental cycle-overlay

On October 8 an accidental overlay of those two charts was read as showing the peak already in and a crash-scale decline next. The reading was one of several possible alignments. After daily price was judged to be tracking the overlay, recipients were given a Dow path near 1750, with 1623 listed as another possible level from index-ratio conversion and a third-wave acceleration point.

Listed levels, puts, and quote-latency

Index puts were opened on October 14, adjusted on October 16, and the following session was reserved for the expected crash day. On that session, delayed quotes and a square-of-nine turning grid were used while size was cut on the first large rally and later re-entered more timidly as fear returned. Quote-latency is the gap between pit prices and the prints a trader can actually use during an extreme session.

The next morning an entry was canceled after the trading pit closed, and trading was then suspended for months.
