Choosing a broker as a beginner: what actually matters

A broker is the intermediary between you and the market. It shows you prices, executes your orders, locks up your margin and computes your costs. None of that is neutral: each step is a place where your result can end up slightly better or slightly worse, and over a few hundred trades those gaps stop being slight.

You also need to understand how it earns its living, because that says a lot about what it optimises for. Three sources, usually combined: the gap between the buy price and the sell price it shows you, a commission per transaction, and financing costs on positions held overnight.

So the right way to choose is not to look for the “best broker”, which does not exist in the abstract, but the one whose model suits you, with the capital you have and the way you intend to work. A broker that is excellent for someone trading ten futures contracts a day can be unusable with two thousand francs.

This is the only knockout criterion on the list. Everything else is a trade-off; this one is not. Before looking at a single figure, identify the authority supervising the entity you are opening the account with, and check the registration directly in that authority’s public register — not on the broker’s own site, where displaying a logo is easy.

Watch out for a detail that catches many people: a group can run several entities in several jurisdictions, and depending on your country of residence you may not be contracting with the one whose reputation attracted you. The exact question is: which legal entity is my contract with, and who supervises it? The answer is in the terms and conditions, and a serious firm does not hide it.

Then check segregation of funds: your money must be held in accounts separate from the company’s own, so that trouble at the broker does not become trouble for you. Finally, look at whether a deposit guarantee scheme exists, what it covers and up to what amount — this varies a great deal between jurisdictions, and many leveraged instruments fall outside all of them.

If those three pieces of information cannot be found in ten minutes, the question is settled and you do not need to look at the fees.

Advertising leads with a minimum spread, usually shown as “from”. It is the least informative number on the page: it corresponds to the best moment of the best day on the most liquid instrument — that is, to a situation you are not necessarily trading in.

The figure to compare is the total cost of a round trip on the instrument you actually intend to work, at the hours you will be at the screen: the average spread observed then, plus any commission on the way in and on the way out. A commission broker with a tight spread and a no-commission broker with a wider spread can land on the same total — or not, which is exactly why the calculation is worth doing.

Add financing costs if you intend to hold positions for several days. Over a few hours they are negligible; over three weeks they can be a serious share of what you were aiming for. Those schedules are published and are read before opening the account, not after the first surprising statement.

Finally, look at the costs that have nothing to do with trading: inactivity fees, withdrawal fees, currency conversion when your account is denominated in one currency and the instrument in another. That last one is regularly the largest hidden cost for a Swiss resident trading dollar-denominated products.

Here is the point that should top every comparison and never does. The basic risk-management rule is never to put more than 1% of your capital at risk on one position. That rule is only applicable if your broker accepts positions small enough for that 1% to be respected given your stop distance.

The arithmetic is simple and worth doing before opening anything. On capital of 2,000, 1% is 20. If your stop sits 30 pips away and the smallest available position loses roughly 1 per pip, your minimum risk is 30 — you are already over the limit at the smallest possible size. In other words, that broker does not let you work properly, whatever its spread.

This is why the availability of micro lots, or of fractional instruments, matters more than almost anything else when capital is modest. A slightly more expensive broker that lets you size finely beats a slightly cheaper one that forces you to risk three times too much.

Do that calculation with your own numbers: your capital, the stop distance your way of working implies, the instrument you are targeting. It takes five minutes, and it often eliminates half the candidates.

Some brokers pass your orders to the market and are paid for the routing. Others take the other side of your positions themselves: when you lose, the house collects. Both models exist legally and are run by serious firms, but the second creates an interest that is not yours, and you have the right to know which one you are in.

This is not an accusation and should not be turned into a theory: a properly supervised market maker hedges its exposure and lives on volume, not on your individual losses. But the information changes how you will read certain situations, and it is published in the execution documentation every regulated broker must provide.

In the same documentation, look for the order execution policy and what it says about slippage and stop orders. A stop is triggered at the level you set but executed at the price available: knowing in advance how your broker behaves during news releases and at the weekend re-opening saves you from discovering the answer at the worst moment.

Welcome bonuses and deposit credits. They come with volume conditions that push you to trade more than is reasonable, which is exactly the behaviour to avoid as a beginner — and that is precisely why they exist.

The maximum leverage offered. High leverage is not an advantage: it defines the largest size you may open, not your risk, and a trader working properly uses only a tiny fraction of it. Choosing a broker because it offers more leverage is like choosing a car for the top number printed on the speedometer.

Referral links and sponsored rankings. A significant share of online comparisons is paid on account opening, which does not invalidate their content but does explain why the same names appear everywhere in the same order. Cross-check with the regulator’s register and with the contractual documentation, which are not paid for.

Finally, how the platform looks. You will be doing your analysis elsewhere, on a charting tool, and using the broker only to place orders and manage positions. An austere but reliable platform beats a flattering interface that freezes at the moment you need to get out.

Shortlist two or three candidates on the regulatory criterion alone, without looking at fees. Open a demo account with each: it is free, it commits you to nothing, and in an hour it teaches you what no comparison will — is the platform clear, is sizing easy to compute, is attaching a stop to the order straightforward.

Then run the minimum-size calculation with your own numbers, followed by the total round-trip cost on your instrument at your hours. By that point there is usually one candidate left, and the choice makes itself.

And bear in mind the choice is not permanent. Changing broker is an administrative formality of a few days, far less costly than spending two years with an intermediary that prevents you from sizing your positions correctly.
