About this desk
One topic, covered once: the market that does not exist until a customer asks for it, and the arithmetic that decides what comes back. This page says how the figures were made, what the desk refuses to do, and how it sits beside the rest of the series.

This desk explains how a composed market - a same-event combination or a bespoke market priced on request - is built, priced, refused and repaired. Every figure derives from ten invented samples and no real operator, sport, player, market or terms page is described. It is 1 of 76 desks in a series that each take one mechanism and explain it.
How the figures were produced
Ten samples were defined first, on the overview page, and every other number on the site is derived from them: a three-leg combination, a month of requests, a set of combination rules, a void leg, the limits, a set of terms pages, a month of turnover, a queue cost, the refusal reasons and a model band. Nothing is quoted from a live operator, and nothing is observed. Where a figure could be read two ways - the difference between a composed price and the product of its legs, for example - it is presented both ways and the arithmetic is shown so a reader can re-derive it.
What the samples show
| Question | Answer |
|---|---|
| What is the subject? | The market a customer composes and the operator prices on request |
| How many samples? | 10, invented, defined on the overview page |
| How many pages? | 17, including this one |
| How are figures sourced? | Derived from the samples; no live operator, market or terms page |
| How is it funded? | One disclosed sponsored partner link, disclosed on every page |
| How many operators are named or rated? | None, anywhere on the site |
What this desk is not
It is not legal advice, and it is not a substitute for the terms of any account. It is not a complaint service: the routes for a dispute are a separate desk in the series. And it is not a guide to composing a market more cleverly - the figures on it are the operator's arithmetic, published so a reader can recognise what they are being shown rather than to help anyone find an edge.
- Defines ten invented samples, with every count and price, on the overview page.
- Derives from them the relationship between the product of a set of legs and the joint chance the model measures.
- Follows a request from the queue to the answer, and counts what happens to it.
- Tests what the terms of a composed market actually state, against the rules a reader needs.
- Puts one month of those markets through the arithmetic, so the price in the product can be read against the cost of producing it.
- The price of a composed market is a joint chance, not a product, and the difference is not a fee.
- A request is a question with five possible endings, and more than half end without a usable price.
- A void leg is re-priced from the remaining legs, and dividing is wrong by 6.7% on the samples.
- The stake limit on a long combination is the payout ceiling divided by the price, not the number in the box.
- Keep your own record: the operator's request log is not published, and 11.0% of accepted markets are never published either.
