A necessary premise, given the topic: this page contains not one affiliate link and I won't tell you which broker to use. 90% of the "best broker rankings" online are advertising dressed as reviews: the writer earns a cut on every account opened. Here you get the method to evaluate them yourself — worth more than any ranking, because conditions change and the method doesn't.
Level 0 — Regulation (eliminatory)
An unlicensed broker isn't evaluated: it's discarded. Verify yourself, in the authority's register (not on the broker's homepage):
- Europe: authorization from a national authority under the ESMA framework — with negative balance protection and mandatory segregated funds.
- UK: FCA. Australia: ASIC. USA: NFA/CFTC (very different rules).
- Check your regulator's warning lists of abusive sites: continually updated, and the first place scam brokers appear.
"Offshore" entities (assorted islands, bought licenses) offer sky-high leverage precisely because they answer to nobody. 500x leverage is not worth your unsegregated funds.
Level 1 — Real costs (not advertised ones)
A trade's total cost is: real spread + commissions + swap + slippage. Each is measured, not read off a homepage:
- Real spread: open a demo and measure the spread in the hours you'll actually trade — including 11pm, news, rollover. The advertised "from 0.0 pips" exists ten minutes a day.
- Commissions: on raw accounts, typically $5–8 per lot round-trip. Always add them to the spread: broker comparisons are made on the total.
- Swap: structural for overnight positions (with the weekly triple swap). On metals and exotics it can erode an entire edge.
- Slippage and execution: only measurable live: difference between requested and executed price, requote frequency, behavior on news. For automated systems, often more important than the spread.
Why I insist on costs has a number: −$127.02 over 50 trades, $118.48 of it commissions. My bot wasn't losing to the market: it was losing to its cost structure. Simulate yours with the dedicated calculator.
Level 2 — The execution model
Market maker: the broker takes the other side of your trade. Not automatically evil (often steadier spreads, same regulation), but the structural conflict of interest exists. STP/ECN: orders go to external liquidity providers; the broker earns from flow. In both cases remember the constant: the broker always earns from your transaction costs — which is why the more you trade, the happier they are, and overtrading is the gift you give them.
Level 3 — The practical test
- Small deposit, immediate withdrawal: before committing real capital, test the full cycle. Withdrawal problems are THE definitive red flag — and the moment you discover them must not be when all your money is inside.
- Support: ask a specific technical question (e.g. "at exactly what time and in which timezone do you calculate swap rollover?"). The answer's quality tells you plenty.
- Platform and API: if you run EAs, check MT4/MT5 compatibility, VPS hosting, and the terms-of-service rules on scalping/arbitrage — some strategies (like latency arbitrage) are explicitly restricted, and finding out afterwards means seeing your profits voided.
Red flags worth an immediate no
- They contacted you (phone, social media, a personal "account manager").
- Deposit bonuses with volume requirements (banned in Europe: whoever offers them isn't ESMA-regulated).
- Return promises, "managed accounts" that double, pressure to top up.
- Withdrawals requiring "taxes paid first" or endless "verifications".
- Untraceable legal seat, convenience license, a name resembling a famous broker's.
