The readiness score is a single 0–100 number that summarises whether your body is in shape to perform today. It's built from four ingredients:
- Sleep quality — duration, deep sleep, REM, and how recovered you woke up.
- HRV trend — how your autonomic recovery compares to your personal baseline.
- Recent stress load — cumulative stress events over the last 48–72 hours.
- Resting heart rate — relative to your usual.
Each ingredient is normalised against your baselines, then combined with weights that emphasise sleep and HRV (the two with the strongest evidence for next-day cognitive performance).
How to read the result:
- 75–100 — green light. You're well-recovered. Good day for higher cognitive demand.
- 50–74 — yellow. Reduced capacity. Worth being slightly more conservative — smaller size, A-setups only.
- Below 50 — red. Recovery is genuinely low. Strongly consider paper trading or skipping the session.
The score is not a prediction. It's a probability shift — over many days, your decisions tend to be better at high readiness than at low. You can override it for any individual trade.
