Psychology as Process, Not Motivation
You cannot “try harder” under stress. You need constraints.
Most psychological trading problems show up as process drift: - entry timing gets worse - size creeps - stops become negotiable - re-entries speed up
The fix is to measure execution separately from outcome. A losing trade can be high quality. A winning trade can be poor quality.
If your journal cannot answer “was this in-plan?”, it cannot help with psychology.
Key Points
- •Psychology shows up as rule drift.
- •Grade execution quality independently from PnL.
- •Constraints beat willpower.
Guardrails That Actually Stop Bad Sessions
Guardrails are stop conditions you pre-commit to.
Use at least two: - Max loss (daily/session) - Max trades (session) - Max time (session)
Then add one behavior guardrail: - Post-loss cooldown - Half-size after rule break - No re-entry without new evidence
Your goal is simple: prevent a bad state from getting “more time and more size.”
Key Points
- •Use a hard stop plus a behavior stop (cooldown or size rule).
- •Make the guardrail visible before you trade.
- •If it is optional, it will not exist when you need it most.
How to Review Psychology Weekly
Review by tag, not by coin.
Weekly review: - Group trades by state tag (tilt/FOMO/fatigue) and compare outcomes. - Identify the highest-cost trigger. - Install one constraint that targets that trigger.
Examples: - Tilt trigger: rapid re-entry after loss. Constraint: cooldown + no re-entry rule. - FOMO trigger: late entries. Constraint: entry window + reduced size on late entries.
Make only one change per week. Consistency wins.
Key Points
- •Sort by behavior and condition.
- •Change one thing per week.
- •Measure whether the constraint prevents a trade, not whether it “feels good.”
