sati

Mindfulness.

Know, at every moment, the position you are in.

ISutra

Furthermore, when a mendicant is walking they know: ‘I am walking.’ When standing they know: ‘I am standing.’ When sitting they know: ‘I am sitting.’ And when lying down they know: ‘I am lying down.’

Whatever posture their body is in, they know it.

— MN 10:6.1–6.2 · Mindfulness Meditation · Middle Discourses (Majjhima Nikāya)

IIPrinciple

Continuous, real-time risk monitoring.

Whatever position the book is in, the system knows it: exposure, drawdown, correlation and the gap between live and backtested behaviour, recomputed as they change.

Limits are set in calm and enforced in motion. Monitoring is not a report read the next morning — it is attention that never leaves the present tick.

Above: a simulated equity curve. Below: the same path as distance from its last peak, DDt = 1 − Vt / maxs≤t Vs, recomputed on every tick. The limit is set before the strategy goes live; the moment the line crosses it, the system acts — not when someone happens to look.
