Constructing a weekly seasonality pivot scaffold

This archive workflow turns one calendar week's average, extreme, and frequency statistics into a five-level pivot-point scaffold. The aim is to judge a single trade inside a historically recurring window, not to treat a seasonal percentage as a forecast.

  • Seasonality work is a calendar map of historically recurring windows, not a prediction engine, and the mapping does not separate economically grounded recurrences from chance alignments.
  • A weekly net change can remain positive when average declines exceed average rises if more sample weeks finished higher than lower, so average rise, average decline, largest rise, largest decline, net change, and rise-or-decline frequency must be read together.
  • The scaffold plots largest rise as R2, average rise as R1, the seasonality-pivot, average decline as S1, and largest decline as S2, then applies those rates to the current week's reference price.
  • R1 and S1 are anticipatory reference levels, R2 and S2 are historical-limit thresholds that can be compared with weekly range, and rise-frequency is only a directional bias when average-loss size does not dominate average-gain size.

A calendar map, not a forecast

Seasonality work is presented as a calendar map of historically recurring windows, not as a prediction engine. Year-long average-return charts and named calendar effects are treated as alerts that still lack the week-level detail needed to become a trading procedure.

Editorial interpretation: the construction that follows is a way to place one trade inside that calendar-aware regime, not a claim that the map forecasts the next weekly close.

Why a single net change is not enough

A weekly net change can remain positive when average declines exceed average rises if the sample contains more up observations than down observations. Reading a seasonal window therefore requires jointly inspecting average rise, average decline, largest rise, largest decline, net change, and rise-or-decline frequency rather than relying on a single net-return figure.

Building the five-level scaffold

Seasonality support and resistance are constructed from historical average and extreme percentage moves. The seasonality-pivot is the midpoint obtained by averaging the week's average change with its median return, then scaling that blended rate onto the current week's reference price.

The scaffold plots five anchors: largest rise as R2, average rise as R1, the blended pivot, average decline as S1, and largest decline as S2, together with the historical share of up and down weeks.

Those percentage rates are applied to the current week's reference price by multiplying it by one plus the historical rise rates and by one minus the historical decline rates.

How the anchors are read

Average-based R1 and S1 are described as anticipatory reference levels, while extreme-based R2 and S2 are described as historical-limit thresholds that can be compared with weekly range.

Historical rise-frequency is treated only as a directional bias, and only when average-loss size does not dominate average-gain size.

From map to a testable procedure

Editorial interpretation: seasonal-analysis maps the historically recurring window so a single trade can be read inside a broader regime. The pivot-point is the falsifiable weekly scaffold built from those average and extreme percentage moves. seasonal-trading turns the calendar-derived levels and frequencies into entry, exit, or abstention rules for the system holding period.
