The research behind EXIT CODE.

Douglas's framework on the consistency problem: knowing what to do versus doing it under pressure. Foundational text for the execution-gap thesis. The course paraphrases his analysis of probabilistic mindset, the need for risk acceptance before entry, and the journal-as-aggregate-mirror framing.

Cited in course Module 3 (Lesson 3.2, the consistency problem), Module 4 (Lesson 4.1, Gate 2 setup discipline). Paraphrased only; no verbatim quotes published.

Tharp's framework on expectancy, R-multiples, and position sizing as the dominant determinant of trading outcomes. The execution variance > system variance thesis: how a trader applies their system matters more than which system. Direct source for Gate 4's R:R minimum logic and the R-multiple language used throughout the course.

Cited in course Module 4 (Lesson 4.2, Risk-Reward Gate), Module 6 (Lesson 6.3, Position Sizing). Paraphrased only.

Tendler's central thesis is that emotions are signals, not noise: greed, fear, anger, confidence problems and discipline problems each point to a specific underlying flaw to map and correct, not a feeling to suppress. His named in-the-moment failure behaviours (chasing price, cutting winners short, forcing mediocre trades, overtrading) and his five tilt types (Mistake / Hate-Losing / Injustice / Revenge / Entitlement) are the source for Gate 1's cooldown and revenge-trade-window enforcement logic and for the Fear/Greed/Impatience/Revenge override classifier used across the gates.

Cited in course Module 2 (Lesson 2.3, The 30-Second Re-Entry), Module 5 (Lesson 5.1, Cooldown enforcement). Paraphrased only. The "amygdala hijack" framing used in earlier drafts has been removed: that term is Daniel Goleman's (Emotional Intelligence, 1995), not Tendler's; we now describe G1's mechanism in Tendler's behavioural terms instead.

The 5 Ds is a pre-commitment technique documented by Gambling Help Online Australia (the AU government-funded gambling-recovery service) as the standard self-help intervention for managing urges. It is a clinical-context expansion of the older 3 Ds (Delay, Distract, Decide) used in NHS smoking-cessation literature, adding Deep breathe (somatic regulation) and Discuss (peer / community / clinician contact). EXIT CODE's product structure implements all five: Delay (the quiz + Baseline pre-commitments) · Distract (the act of answering 8 questions) · Deep breathe (the EXTEND verdict's somatic block) · Decide (the verdict screen) · Discuss (the Discord #recovery-talk channel for peer contact, plus pinned AU / US / UK gambling-help hotlines for clinician access).

Primary source: gamblinghelponline.org.au · Manage gambling urges with the 5Ds. Cited in course Module 2 Lesson 2.3. The cross-application from gambling-recovery to trading-discipline is appropriate because the DSM-5 / DSM-5-TR Gambling Disorder Criterion A.6 ("'chasing' one's losses") is the clinical pattern the methodology is designed to interrupt. Earlier drafts mis-attributed this technique to Brewer's The Craving Mind; that has been corrected throughout, and the 3 Ds was upgraded to the canonical 5 Ds per the AU public-health framework.

The urge surfing technique was originated by Marlatt (& Gordon) in relapse-prevention literature and is now widely used in DBT and ACT practice. It is the complement to the 5 Ds: where the 5 Ds work by interrupting the urge (Delay, Distract, Deep breathe, Decide, Discuss), urge surfing works the opposite way, by observing the urge as a wave that rises, peaks, and falls on its own without action. EXIT CODE integrates urge surfing into The Delay's EXTEND verdict alongside the somatic Deep breathe instruction: the customer has been told to wait 10 minutes, and urge surfing + deep breathing are what they DO during that wait.

Public clinician worksheet: TherapistAid · Urge Surfing Handout. Brewer's The Craving Mind attributes the urge surfing technique to Marlatt directly. The Delay's EXTEND verdict includes a 3-step adaptation of the technique with the wave-curve visual, attribution, and the explicit "this is not therapy" disclosure.

The DSM-5 / DSM-5-TR Gambling Disorder diagnostic criteria include "After losing money gambling, often returns another day to get even ('chasing' one's losses)" as criterion A.6 (verbatim from the manual). EXIT CODE applies this clinical pattern as the structural identification of revenge-trade behaviour, not as a diagnosis of any trader, but as the documented behavioural mechanism the methodology is designed to interrupt. The phrase "returns another day" makes this a multi-session pattern, which is precisely why the Circuit Breaker (G8) operates as a next-session lockout, not just an intra-day cap.

Referenced in course Module 2 (Lesson 2.2, What Happens in the 3 Seconds Before the Override). Criterion referenced by number, not reproduced verbatim. The course is explicit that the framing is behavioural-analogue, not clinical diagnosis.

Hougaard's argument in Best Loser Wins is the central thesis behind Gate 5: the difference between traders who survive and traders who blow up is losing smaller, not picking better trades. The one-way-stop principle (stops only move closer to price, never further) is the structural application of his argument. Hougaard is a high-stake retail trader who has documented his own account history publicly; the credibility comes from the trading record, not a clinical credential.

Cited in course Module 6 (Lessons 6.1, 6.2, 6.3, a full module dedicated to G5). Paraphrased only. The phrase "Hougaard's cardinal rule" appears nowhere in the book; it was EXIT CODE's earlier framing, since corrected to "the one-way-stop principle Hougaard makes in Best Loser Wins" across all surfaces.

Nekritin & Peters's price action manual contains, in Chapter 12, the diagnosis the course's Module 1 is built on: "The Cycle of Doom", a three-phase pattern verbatim from the book: "The first phase is the search. The second phase is the action. And the third and final phase is the blame." Traders cycle through systems because the underlying execution problem is never tested. Their second foundational concept (used for EXIT CODE's gates framing) is a "just-this resistant" discretionary system: rules so concrete the trader cannot rationalize making exceptions "just this time." The book also documents Worst-Case Planning, the Sleeping Point (size so you can place a trade, accept the risk, and sleep), and the Bank Manager mental model, a "trading-buddy" external accountability layer that maps directly to EXIT CODE's community / UNTAGGED accountability surface. Used with verbatim quotation marks + chapter attribution for the specific passages (M1 + M2 of the course); paraphrased only for the rest.

Cited verbatim in course Module 1 (5 passages, ~280 words across Lessons 1.1–1.5) and Module 2 (8 passages, ~240 words). All verbatim citations bracketed with author + chapter inline. Cumulative ~530 words across the course, within fair-use range for educational quotation of a commercial trading manual; routed through publishing-lawyer review for sign-off.
