The Trader’s Nervous System: Executing Under Uncertainty

Most traders don’t blow up because they lack a model. They blow up because their state collapses when risk is real.

Common nervous-system traps

• Chasing: Over-trading to escape discomfort.

• Avoidance: Skipping valid setups after a loss (freeze).

• Revenge: Size up to soothe ego (fight).

• Leakage: Moving stops, early exits, late entries—micro acts of fear.

Pre-market protocol (15 minutes)

1. State check (2 mins): Scale 1–10—fatigue, stress, urgency. If >7, reduce size or stand down.

2. Bias build (5 mins): One directional bias, two invalidation points. No second bias.

3. If/then plan (5 mins): “If price reclaims X and holds, I do Y. If it fails at Z, I stand down.”

4. Boundary set (3 mins): Max trades, max loss, time cut-off. Write it. Honour it.

In-trade protocol

• Rule of one: One decision at a time. Enter or manage—not both.

• Breath anchor: 4 seconds in, 6 out. No decisions on the inhale.

• Stop sanctity: Stops are not suggestions. They are the price of staying in the game.

Post-trade debrief (5 minutes)

• Fact: Entry, exit, stop, R multiple.

• State: What I felt; where I deviated; what triggered me.

• Fix: Precise behaviour to test next session (e.g., “break even only after HTF reclaim”).

• Forgive: Close the loop so the next trade isn’t a reaction to the last.

Metrics that actually move performance

• Execution score (0–5) independent of P&L

• Deviation count (stops moved, late entries, early exits)

• State journal correlation (what emotions precede errors)

• Time in chair vs. valid opportunity time (reduce idle risk)

When to step back

Two consecutive max-loss days, or rising compulsion, means stand down and reset. Professionals protect capital and state first; amateurs protect ego.
