Reference

Every governing metric is tracked as a rolling series with stability bands and a z-score against its own history. Readings inside the band are treated as variance and left alone; sustained drift toward the outer bands raises a structural flag that outranks the P&L column.

A rolling metric leaving its normal band: inside ±1σ is weather; a sustained walk toward −2σ is climate - and climate gets flagged.

Session interplay

Regime plus session decides everything downstream.

The switch is deliberately binary, but its output cascades: it selects the branch family, the break-even level, whether trailing logic activates, and which volatility tools engage.

Trend classification requires both conditions: elevated ATR regime AND in-session — never one alone.
The regime read is captured into the Journal as ATR State, making regime-conditional performance auditable later.
Downstream chain: regime → branch → BE level → coefficient tools → checkpoint flags — one switch, five consequences.

Session gating

The open is where the switch earns its keep.

The assistant gates entries around the two operating windows — London 02:00–07:00 ET and New York 07:00–11:30 ET. The manual's read on session dynamics is specific: shading that flips ON shortly after a session open with the ATR line green is prime continuation territory — volatility momentum building exactly when participation arrives. Shading that flips OFF mid-session is the opposite instruction: downshift to Normal management and favor mean-reversion entries only if the other tools align.

The gray zone

Between the yellow line and the orange line, nothing has been confirmed.

ATR above its SMA but below the threshold is the watch zone: volatility is above normal but hasn't cleared the multiplier that confirms a Trend regime. It is often a warming-up phase — a buildup before a session open. The doctrine's instruction is precise: keep applying Normal rules, and stay alert, because a break above the orange line can flip the regime quickly. The speedometer metaphor from the manual: below yellow is under the limit, between yellow and orange is cruising faster, above orange is racing — and only racing changes the rules.

MTF stepping

The pane updates on the regime timeframe's close, by design.

With atrTF set to 60, a trader on a 5m chart is reading hourly ATR — so the pane updates on the hourly close and moves in visible steps within the hour. The manual calls that behavior normal and desired: regime stability over responsiveness. A regime that repainted every five minutes would generate exactly the management flip-flopping the switch exists to prevent. Traders wanting faster updates lower atrTF deliberately, accepting more regime noise as the price.

The two-key lock

Regime and session must both turn before doctrine applies.

An Expanded reading during the London open and the same reading in the Asian drift are different management environments, and the assistant treats them so: doctrine selection keys on the regime-session pair, not the regime alone. The two-key design prevents the classic error of applying high-energy management to low-energy hours.

Reference

Reading the pane — the three-position read

ATR position	What it means	Management
Below the yellow ATR_SMA	Volatility below average — flat or choppy	Normal rules, no anticipation
Between yellow and orange	Above average, below the k threshold — warming up	Normal rules, alert for a breakout flip
Above orange, pane shaded	Confirmed Trend regime	Trend rules: BE 1.6R, ATR trail

Edge cases & failure modes

Where it can mislead

!Shading on almost all the time → sensitivity too loose: raise k toward 1.30 or lengthen maLen.
!Choppy, frequent flips → lengthen maLen or atrLen, or raise atrTF (90/120) for a steadier regime.
!Pane looks frozen on low chart timeframes → it updates only on atrTF closes, by design; lower atrTF only if faster updates are worth the noise.
!A flip just happened → don't chase it; wait for the next pullback or structure confirmation.

Operator briefs on this territory.

Deep dive — 01

Trend classification requires elevated volatility and session participation. Either alone is not a partial answer.

Same ATR reading, two different worlds. The switch requires both keys because one key describes nothing.

Read the full brief →

Deep dive — 02

A binary switch with a five-deep cascade makes the classification the most expensive decision of the day.

One field, five consequences, none of which can be corrected once the trade is running.

Read the full brief →

Deep dive — 03

Out of session defaults to Normal regardless of what the volatility reading says.

No exception clause. The switch fails toward the branch that cannot be hurt by being wrong.
