The key idea

Worked example

Each closed trade logs its worst adverse excursion and best favorable excursion. The lab plots them into quadrants and pairs the picture with capture efficiency, giveback, and fee drag - then the EV Driver Diagnostics rank which repair (entry location, coefficient, trail logic, cost avoidance) would move net expectancy most.

Every trade plotted by pain taken (MAE) versus opportunity generated (MFE). The four quadrants diagnose entry precision and exit management at a glance.

The chain in order

Eight steps, each conditional on the last.

The session check passes — inside the London window. The ATR BE Assistant's pane is shaded with the ATR line green: Trend regime, so the branch family is trend and BE doctrine is 1.6R. The EW HUD shows the higher frames lime while 5m and 15m finish a corrective — a ★-grade alignment. The continuation HUD scores 5/6 with directional consensus: A-grade. The Distance Matrix converts live ATR to 9.5 pips; at the 2.0 coefficient that is a 19-pip stop, in a Normal-to-High London zone against a Developing baseline. The throttle's authorized per-trade risk accommodates that distance. Trend Partial executes: 50% banked at 1R, break-even at 1.6R, ATR trail on the remainder. And capture writes all of it down.

Where it could have died

Five vetoes, any one of which ends the trade politely.

The same chain, read as exits:

Out of session → Normal handling regardless of ATR state; the trend thesis never starts.
Pane unshaded or ATR red → Normal rules or heightened selectivity; no 1.6R doctrine.
Convergence below MinN, or split across sides → structure disagrees; the setup loses its grade.
Continuation score 4, or high-but-split → B-grade; wait rather than enter.
Insufficient baseline or stop distance unsizeable inside authorized risk → conservative coefficient, or no trade.

The reverse read

On Saturday, the chain runs backward.

Review inverts the flow: weak capture on the runner traces back to the coefficient decision and its zone context; a stop-out traces to whether the exit was structural or noise inside a 19-pip envelope; a missed continuation traces to which engine's veto fired and whether it was right. Because every step wrote its field at decision time, each question has a recorded answer — the week's trades become a dataset instead of a memory.

The paper trail test

A stranger could reconstruct this trade from its records.

The worked example's quiet point is auditability: every decision — the convergence grade, the ATR distances, the clearance checks, the management flags — exists as a logged value a third party could follow without asking the trader anything. That reconstruction test is the standard every MARS trade is held to.

The decision log, step by step

Step	Tool	Read	Consequence
1	Session window	London, in-window	Trading is permitted at all
2	ATR BE Assistant	Shaded, ATR line green	Trend family · BE 1.6R · trail doctrine armed
3	EW Convergence	Higher TFs lime, lower TFs finishing corrective — ★	High-conviction structural agreement
4	Trend Continuation	Score 5/6, consensus long	A-grade regime — arrow tradeable
5	Distance Matrix	9.5 pips × 2.0 = 19-pip stop · Normal/High zone · Developing baseline	Distance known, reliability graded
6	Throttle authority	Per-trade risk accommodates the distance	Position sizes inside authorized risk
7	Execution	Trend Partial: 50% at 1R · BE 1.6R · ATR trail	Doctrine runs as armed
8	Capture	Every read written as a Journal field	Saturday can grade the whole chain

Deep dive — 01

Run the same trade with the switch reading Normal, and the paths are identical until 1.4R.

One field changed, nothing else. The two trades are the same trade until the first protection level.

Deep dive — 02

By the time the entry prints, almost every decision in the trade is already fixed.

Six of the seven decisions are locked before the entry bar. The bar chooses only the moment.

Deep dive — 03

Several fields this trade wrote will not be read by anything for months.

The cost is paid this week. The payoff needs a sample. That asymmetry is what erodes the record.
