A monthly seasonal heatmap as a three-gate regime filter

A calendar of date-linked clusters

A monthly calendar was filled with equities and funds that had historically repeated a directional move on a given date or short window. The screened set was described as about 250 stocks and funds chosen for those consistent date-linked moves.

Those seasonal projections were formed with a look-ahead of about 30 days. Each calendar day was colored so that deeper green or red marked a more one-sided historical bullish or bearish session. That color depth is the calendar heat on the month.

From a date to a trade window

Choosing a date opened a candidate list split into bullish and bearish rows. The rows could be sorted by historical profit, accuracy, average profit, and the window’s end date.

Selecting a symbol showed the implied buy and sell dates together with a 10-year bar chart of that same window’s yearly results. The implied dates define the trade window. The multi-year display is the set of yearly outcome bars.

An unusually large or small yearly bar could be opened as that year’s price chart so the actual path of the seasonal window could be inspected. That inspection is the chart drill-down.

Three gates around one setup

In this editorial reading, the same archive tools are used as a three-gate procedure. The first gate isolates a date-linked cluster: a historically repeating directional move tied to a calendar date or short window rather than to a headline.

The second gate stays on that trade window and reads the yearly outcome bars so a mixed record is visible before any single year is treated as the pattern. A chart drill-down on an unusually large or small bar asks whether that year’s price path still looks like a repeatable chart structure. One standout year is not allowed to carry the idea.

Only then does the third gate open. The month’s green-red mix is read as a regime vote that may confirm, delay, or force abstention on that single setup.

The month as a regime vote

The archive treated the month’s mix of colors as a market-regime backdrop, including around scheduled policy events, rather than as a single-name forecast alone.

A greener monthly map was read as a cue for an upside equity-index regime. A redder or more mixed map was read as a reason not to assume that backdrop.

The editorial use of that backdrop is limited. Calendar heat can support the isolated setup, postpone it, or argue for staying out. It does not replace the yearly check, and it does not turn every name on the day’s list into the same decision.
