The future can't be fitted.

A backtest can always be tuned to look good. This can't: every organism was locked to its setting, before any of these prices existed, and now trades forward hour by hour with paper money. Recomputed from its first bar every hour; nothing is ever re-tuned.

Hash chain

Every hourly update adds a link whose SHA-256 covers the previous link and this hour's numbers plus the hash of the exact prices used. Rewriting any past hour would break every link after it. Save a hash today and check it later.

live/chain.json · prices used: live/hist-live.json · numbers: live/live.json

Recompute it

The numbers come from the same engine files as the backtest (Data & method). Run server/live/forward.mjs from the source with live/hist-live.json and you get the same live.json.
