The measured-cost table

In plain words: what trading has actually cost, measured from each fill’s own quote receipt — never estimated, never modeled after the fact. Costs are the quiet killer of most trading ideas, which is why this table is a standing exhibit rather than a footnote.

Measured from each FILL’s own quote receipt: both legs valued in USD at the fill’s mark, the gap being the quoted LP fee plus price impact actually paid. A negative total means the quoted route beat the mark used to value the legs — price improvement, recorded as-is. Paper mode charges no router or priority fee, and says so on every receipt (§5). Costs are facts, not verdicts — the referee already nets them.


Compiled from the ledger’s fill receipts by the press; re-rendered at boundaries and closes, never live.
