prices — the SS5 walk
The daily tape — 13.6 million closing prices and the bars behind them. The last close is what everything else revolves around, so this lane is measured before anything downstream is allowed to lean on it.
One source per sheet; every step CERTIFIED or OWED by BrainTrust Staff, matched against the book’s page.
