What you put in
Money and entered positions — one figure. An external withdrawal reduces it, and every non-base amount is converted at the operation's own date, not today's.
Fix one old row, and the spreadsheet stops being true.
Reckon keeps one ledger of what actually happened. Average cost, cash & equivalents, what is still at risk — every figure is derived from that ledger, not maintained by hand.

Three numbers, and where they come from.
What it's worth now
Positions at market price, cash & equivalents, and what remains at risk. If a price was missing for something, it shows — it is never silently swapped for zero.
What the coins cost you
The average purchase price is derived from a single event ledger, not entered by hand: correcting any operation recalculates everything that follows from it.
What a spreadsheet cannot do for you.
Correcting an old row breaks everything below it.
One event ledger. Correct any operation and everything downstream recomputes.
Prices are typed in by hand, and go stale the same day you type them.
Market prices are fetched per asset per day. When a price is genuinely missing, the figure says so instead of quietly becoming zero.
A deposit in another currency is converted at whatever rate you remembered.
Every non-base amount is converted at the rate of its own date, not today's.
Average cost is a formula you wrote once and no longer trust.
Average cost is derived, never entered, and recomputed from the ledger every time you read it.
A missing price is shown, not swapped for zero.
Length is the size of the position; the tail is which way it went. When there is no price at all, the bar is hatched — the far end is unknown, and the figure beside it says so.
