Month-turn window, posture, and an open menu

The archive treats a month-turn seasonal effect as something that can be defined several ways, then handled through posture, an opening print, and later chart conditions. In this editorial reading, that workflow is taught as one locked turn-of-month-window, a seasonality-posture set in advance, and a short menu that includes skipping the open.

  • The archive lists several last-days and first-days windows, plus a last-close to second-or-third-day-open window, as alternative definitions of one turn-of-month-window, and states that the effect can be observed under any of those choices.
  • Window choice is tied to other methods and to whether seasonality-posture applies to every window, one consistent window, or a selective window given extra signals.
  • A mid-month run of five consecutive down days on sessions labeled -12 through -8 is used as window-entry-state for a last-seven / first-five window and to start planning for the next open.
  • Editorial reading: convert that next open into an open-participation-menu and after-open-chart-condition list, and keep a calendar-window-risk-plan, because flat months, selloff months, and a failed reversal are treated as expected.

One effect, several window definitions

The archive lists several last-days and first-days windows, plus a last-close to second-or-third-day-open window, as alternative definitions of one month-turn seasonal effect. It states that the month-turn effect can be observed under any of those window choices.

In the language of this article, each of those choices is a turn-of-month-window: a calendar interval spanning the last sessions of one month and the first sessions of the next.

Seasonality-posture before the window

Window choice is tied to the trader’s other methods and to whether posture is applied to every window, one consistent window, or a selective window given extra signals.

Seasonality-posture is the stance chosen before any candidate window opens, including how strictly that window will be traded. Editorial note: locking the definition first keeps later open rules from rewriting the calendar interval after price has already moved.

Window-entry-state in a mid-month case

A mid-month case of five consecutive down days on sessions labeled -12 through -8 is used to mark entry into a last-seven / first-five window and to start planning for the next open.

That observed price action is the window-entry-state. It is used to decide whether to engage or wait once the calendar window begins.

The open-participation-menu

Open-handling options include a market-on-open buy, a limit-on-open order when a specified price is allowed, and skipping the open entirely.

Editorial reading: those options form an open-participation-menu, a short list of mutually exclusive ways to take, limit, or skip the opening print.

After-open-chart-condition list

After-open plans include a down-open reversal aimed at a gap fill, a prior-close crossover higher, a pivot crossover toward first resistance, a pullback-to-support reversal after an up open, and a first-resistance crossover toward second resistance after an up open.

Editorial reading: each item is an after-open-chart-condition, a price-structure trigger used only if the open itself is not transacted.

The same open and after-open scenarios are described as usable with a broad-market or sector hedge if selected names fail to rally.

Calendar-window-risk-plan

Flat months and selloff months inside the same windows are treated as expected variation that requires a failure plan. That reserved set of actions is the calendar-window-risk-plan.

The write-up states there is no guarantee of a reversal even when the month-turn window and its alternative timeframes are understood.
