Who sets your price: central order book versus counterparty model

Before comparing, it is worth establishing that the market maker role is legitimate and necessary. Without someone willing to quote a bid and an ask continuously there would be no continuous liquidity, and trading would be far worse for everyone. The problem is never the role. It is who performs it, and against whom.

In the first architecture the broker routes your order to the best available price and charges for the service. In the second, the broker is the market. These are different business models, both legal, and both advertised in surprisingly similar language.

In a central book there is a possibility that disappears entirely in the other model: you can choose which side of the spread to be on. By posting a limit order you supply liquidity, and then you do not pay the spread — you earn it.

This is not a technicality. For any strategy whose edge is measured in a few basis points — and almost every real, demonstrable edge is of that size — the difference between paying the spread and earning it is the difference between a positive and a negative result. A basis point is one hundredth of a percentage point.

• The price is public and identical for every participant.
• The counterparty is anonymous and does not hold your account.
• Execution is recorded and can be audited afterwards.
• You can supply liquidity instead of taking it, flipping the sign of the cost.

That the counterparty is anonymous looks like the smallest item on the list and is the most valuable one. A central market does not know who you are, how much capital you hold or where you placed your protective order. Whoever is both your platform and your counterparty does.

There is a family of leveraged products in which you acquire absolutely nothing of the underlying asset. What you sign is a bilateral contract with the provider: if the index rises, the provider pays you the difference; if it falls, you pay them.

Put plainly: someone who believes they are buying a stock index of a hundred companies may own not a single share, no fund unit and no exchange-traded contract. What they own is a payment promise from the firm that sold them the product, whose value depends on that firm remaining solvent and continuing to honour the contract. Counterparty risk stops being an abstract concept and becomes the principal risk.

The figure providers are required to publish themselves

In the European Union and the United Kingdom, supervisory intervention on these products requires every provider to display, alongside its advertising, the percentage of its own retail accounts that lose money. It is not an outside critic's estimate or the result of an independent study: it is the house's own figure, computed on its real clients and published by regulatory mandate. The figures the sector declares typically sit between seventy and eighty per cent.

That warning has been on screen for years and almost nobody processes it for what it is: the aggregate result of the product you are about to buy, published by the party selling it to you and verifiable on their own page.

When a single entity holds your account and is also the counterparty to your trades, information asymmetry stops being a suspicion and becomes an unavoidable consequence of the architecture. That entity knows, out of operational necessity and in real time, things about you that no other market participant knows.

• The exact level of your resting protective orders, because they live in its system and not in a public book.
• Your margin level and how far you are from a forced liquidation.
• The full result history of your account, and therefore your statistical profile as a counterparty.
• The aggregate distribution of resting orders across its entire client base: a map of where the pain concentrates if the price moves.

Precision matters here, because precision is what separates analysis from an outraged video. That this information exists and is available to one party does not prove it is used against the other. What can be stated without argument is that the asymmetry exists by design, that whoever holds it has an economic interest opposed to yours, and that there is no mechanism allowing you to verify from outside what is done with it.

The conflict of interest requires no bad faith: it is structural. When your position lives on the house's own book, the house's result is the mirror image of yours. That is arithmetic, not accusation. Which is why the right question is not “are they cheating me?” but “who is my counterparty, and who decides that?”.

None requires advanced knowledge or privileged access. All are answered with public documentation, and all should have an answer in under half an hour. They are the difference between trading and knowing where you stand.

1. Which authority is the entity signing your contract registered with, and under which category? Both are public. The contracting entity may not be the brand in the advertising.
2. When you trade, do you acquire the asset, a fund unit, an exchange-traded contract, or a bilateral contract with the platform itself? If it is the last one, the platform's solvency is part of your risk.
3. Where is the mandatory notice with the percentage of retail accounts losing money, and what is that house's actual number? If the product requires it and you cannot find it, that is already information.
4. Does the firm publish where it routes orders and whether it receives payment for that flow? In jurisdictions where it is mandatory, that report exists and sits on their website.
5. Are your funds segregated from the firm's own assets, and which compensation scheme covers the balance if the firm fails? The coverage limit is a specific figure, not a marketing promise.

If the answers turn out to be that your platform acts as an agency broker, with exchange-traded instruments and segregated funds: perfect, now you know with certainty instead of assuming. The point of this report is not that you change platform. It is that you do not trade one more day without knowing who you are trading against.
