Deribit settles its options and futures book every day at 08:00 UTC. Binance does not settle its perpetuals at all, the position stays open until you close it or get liquidated. Bybit sits in between, resetting every eight hours. Three exchanges, three completely different answers to the same question: when does a gain actually become real. If your reporting process treats all three the same way, and most do, you have already lost the argument with your auditor before the call starts.
That is the part almost nobody outside a live derivatives desk actually understands, and it is also why the mismatch between your trading desk's P&L and your accounting team's P&L is not a bug. A trader cares about one thing: am I making money on this position right now. Ask them for today's number and they will give it to you in seconds. Your accounting team is answering a harder question: what has this position realised, and what remains unrealised, under a method that holds up regardless of who is asking. Ask them for the same position and, if they are doing it properly, they will come back with a different number to the trader's. Both are correct. Neither is a mistake. The reason is not sloppiness on either side, it is that nobody has modelled the fact that Deribit, Binance and Bybit were never playing by the same rules in the first place.
We have sat inside the reconciliation process at exchanges and custodians running live derivatives books, and the same break shows up almost everywhere: an options position where quantity and price match perfectly between systems, but the value does not.
The cause is nearly always the same. The opening position gets revalued in the front office, and that revaluation lives in the spot lines the trading desk sees, but it never flows through to the options P&L the accounting team is reconciling against. Nothing is wrong with either number. They are describing two different moments in the same position's life, and until someone builds the bridge between them by hand, they will keep disagreeing.
The same pattern turns up in a handful of other specific, recurring places:
Most teams handle all three the same way: a spreadsheet, a person, and several days at the end of each period spent explaining the gap rather than closing it. That works until volume, venue count, or a licensing deadline makes several days too slow.
As institutional derivatives activity scales across options, futures and perpetuals, more finance teams are being asked to close daily rather than at quarter end, often against a swap dealer registration or similar licensing requirement rather than a preference. That is where roughly right stops being good enough.
Both numbers can be true at once and still never match, because they were never measuring the same thing to begin with.
The only way to close that gap properly is to stop treating accounting P&L as a derivative of the trading desk's number. It needs its own independent, position-level tracking of realised and unrealised gains, calculated from trade history rather than backed into from a blended equity figure, with each venue's settlement behaviour modelled on purpose rather than assumed to be the same everywhere.
This is exactly the gap Cryptio's derivatives module is built to close, and it does it in three specific ways.
Cryptio has mapped how each exchange actually settles derivatives, Deribit's daily reset at 08:00 UTC, Bybit's eight-hour cycle, Binance and OKX perpetuals that carry unrealised P&L open until close or liquidation, and built a connector and revaluation schedule for each one individually.
That matters because a single reconciliation model applied across all of them, which is what most tooling defaults to, will misstate at least part of the book on any exchange that does not match the assumption. Getting this right also means the opening revaluation problem described above gets caught at source, because the connector already knows which venue it is looking at and what that venue's revaluation behaviour should look like.
Underneath that, we run two separate books. A trading ledger tracks the life of the position itself: when it opens, when it closes, when it rolls into a new contract. A completely separate asset ledger tracks the collateral sitting behind it, the crypto or USDC that is locked up as margin.
Spot, futures, options and perpetuals each get their own accounting model inside this structure, rather than being forced through one generic template, because that forcing is exactly what creates the valuation breaks a lot of teams spend days chasing at period end.
Rather than relying on an exchange's own average-cost output, Cryptio recalculates P&L from trade-level history using FIFO, and reports the realised and unrealised split at the position level rather than as one combined number.
Most platforms collapse this into a single blended equity figure and call it done. That split, calculated from first principles rather than backed into, is increasingly what auditors and regulators want to see, and it is also what makes it possible to explain any residual gap between the desk's view and the books in one sentence instead of a week of manual tracing.
4. Accurate representation of cash balance & unrealised P&L
Because realised and unrealised gains are already tracked separately at the position level, Cryptio can always show exactly how much of a reported balance is actual cash or settled value, and how much is unrealised gain sitting on an open position that has not been realised and could still move the other way.
That distinction is the one most reporting glosses over, and it is often the first question a CFO or auditor actually wants answered: not just what is the number, but how much of it can we rely on as cash today.
A close that holds up under audit does not need the trading desk's number and the accounting number to match. It needs:
That is a considerably lower bar than most teams assume, once the reconciliation is built to expect the gap rather than fight it every period.
Derivatives activity in crypto is only going to get more institutional, and institutional books get audited. The firms that treat the trading-versus-accounting gap as a known, modelled part of the process, rather than a monthly fire drill, are the ones that will close faster as volume grows, not slower.
If your team is still reconciling this gap by hand every close, it is worth a conversation.
