## Fatigue makes rules feel optional

A trader can follow the plan for hours and still lose control late in the day. Attention drops, patience thins, and small frustrations start to compound.

Late-day rules need to be stricter because the trader making the decision is not the same fresh trader who wrote the plan.

- Set an end time before the session
- Reduce size after long screen time
- Skip low-volume chop
- Do not start a new recovery campaign late

## Boredom can look like opportunity

When nothing happens for a while, traders may lower their standards just to be involved. That is still overtrading, even if it feels calm.

A good plan names the conditions that are not worth trading.

- Define no-trade conditions
- Take scheduled breaks
- Avoid forcing the last hour
- Review missed trades after the close

## Use fatigue scoring as a stop signal

Tilt Blocker includes session-fatigue scoring because time itself changes decision quality. Long sessions deserve more friction.

If alerts appear late in the day, the best trade may be closing the platform.

- Respect late-session alerts
- End after repeated warnings
- Do not chase the daily target
- Protect tomorrow from today

## Session template

1. Stop touching the order controls for at least 30 seconds after a loss.
2. Require a fresh setup reason before any re-entry.
3. Close the platform when speed, fatigue, or frustration becomes the main driver.

## Mistakes to avoid

- Taking the next trade because the last one hurt.
- Clicking faster when the setup quality is getting worse.
- Treating cooldowns as optional once adrenaline is high.
