The Total Value tile on the book in the capture reads 51,715.70 USD, labelled USD equivalent, above a table whose type filters separate SPOT CRYPTO from PERP CRYPTO. Those two filters exist because the rows behind them are economically different objects, and the moment both populations are present, a single total is adding a quantity of owned assets to a quantity of financed exposure.
That sum is not slightly imprecise. It is a category error, and it is the one that produces the worst thirty seconds of an allocator meeting, when somebody asks what your gross exposure is and the only number on the screen is a total that answers neither gross nor net nor equity.
What each row type actually contributes
A spot row is straightforward. You hold the asset, you paid for it in full, the value is both what you own and what you are exposed to, and the worst case is the asset going to zero.
A perpetual row is a derivative position with three separate quantities attached to it, and any one of them could reasonably be called its value. Notional exposure, which is contract size times mark price and is what moves when the underlying moves. Margin posted, which is the capital committed against it. And unrealised profit on the contract, which is the mark to market since entry. Those three can differ by an order of magnitude on the same position.
Before you build anything on top of a mixed table, establish which of the three your Value column is carrying for a perp row. Do it empirically rather than by assumption: take a single position whose contract size, mark and margin you know from the venue, and compare each of the three candidate figures against what the row displays. It takes one position and five minutes, and it determines whether every aggregate you have been quoting is an exposure number or a capital number.
The three lines that replace one total
A mixed book needs three numbers presented together. Any one of them alone is misleading, and the relationships between them are what a professional reader is actually looking at.
| Line | What it sums | What it answers |
|---|---|---|
| Gross exposure | Spot market value plus absolute notional of every derivative position, long and short alike | How much market is this book touching |
| Net exposure | The same set, signed, so shorts offset longs in the same underlying | Which way does the book lean |
| Equity or NAV | Owned assets plus cash plus margin balances plus unrealised on open derivatives | What is actually ours |
Gross divided by equity is leverage, and it is the number that tells the reader whether the book can survive a shock. A book with 51,715.70 of equity and 40,000 of gross exposure is unlevered and boring. The same equity carrying 300,000 of gross is a completely different institution, and no single total value figure distinguishes between the two.
Net alone hides the same information in the other direction. A long spot position offset by a short perp on the same underlying nets close to zero, which is accurate about directional risk and silent about basis risk, funding cost, liquidation risk on the short leg and counterparty exposure on both. Net without gross is how a book that looks flat carries a position that can still cost you a large fraction of equity.
Where funding, margin and liquidation land
Three things live in a perpetual position that have no spot equivalent, and each of them needs somewhere to sit in your reporting or it will surface as an unexplained drift in equity.
- Funding. A perp position pays or receives funding on a schedule, and over a long hold that flow can dominate the price move. It is a carry line, not a price line, and burying it inside unrealised profit removes your ability to attribute a return to the trade rather than to the financing.
- Margin. Collateral posted against a derivative is not free capital, and any dry powder figure that counts it is overstating what you can deploy. If the collateral is a volatile asset rather than a stablecoin, it is also a second exposure, which means a market fall reduces both the position value and the collateral supporting it at the same time.
- Liquidation. Spot positions decline. Derivative positions can cease to exist at a price the venue chooses. Distance to liquidation belongs in the risk pack as a live figure per position, because it is the mechanism by which a bad week becomes a permanent loss rather than a drawdown you can sit through.
None of the three shows up in a table that reports one value per row. They have to be carried alongside, and the desks that do this well keep them at position level rather than only in aggregate, because the aggregate hides which single position is the one that will be closed for you.
Sizing rules break under the same arithmetic
Position limits expressed as a percentage of the book inherit whatever denominator confusion is in the total. A 10 percent limit against a total that includes perp notional is not a 10 percent limit in any risk sense, because a perp position sized at 10 percent of that inflated total might consume a small fraction of capital while carrying a multiple of it in exposure.
Express derivative limits in the units that constrain them. Notional as a share of equity, which is the exposure constraint. Margin as a share of free capital, which is the funding constraint. And distance to liquidation in percentage terms, which is the survival constraint. A single position can be inside two of those and outside the third, and the one it breaches tells you exactly what to reduce.
The same applies to concentration. Two rows on the same underlying, one spot and one perp, are one bet as far as a risk committee is concerned, and any concentration figure computed row by row will understate it. Aggregate by underlying before you compute concentration, then present the split by instrument type underneath.
Presenting a mixed book so the question does not come back
What survives review is a presentation where the reader never has to ask which number they are looking at. In practice that means four things stated together on the front page of any exposure pack.
- Equity, with its composition broken into owned assets, cash and stablecoins, margin balances and unrealised on open derivatives. This is the anchor and every ratio underneath refers to it.
- Gross and net exposure, each split by instrument type so the reader can see how much of the gross is derivative rather than spot, and by underlying so the netting is visible rather than assumed.
- Leverage as gross over equity, with the prior period figure beside it. The level matters less than the direction, and a rising leverage line with flat equity is the pattern that gets asked about.
- The financing lines, meaning funding paid or received over the period and margin utilisation against the venue requirement, with the closest liquidation distance in the book named explicitly.
The discipline behind all four is refusing to let one figure serve two purposes. The consolidated total on the screen is a legitimate number for the question of how much value is connected. It is not an exposure figure, it is not equity, and the fastest way to lose an allocator's confidence is to present it as though it were either.
