How to Choose a CFD Broker: 11 Filters That Actually Matter
Most broker comparison sites rank by affiliate payout, not by what matters to traders. Here are 11 filters that actually affect your trading experience — and how to evaluate them.
1. Regulation
This is non-negotiable. A regulated broker is accountable to a financial authority. Look for: FCA (UK), CySEC (Cyprus), ASIC (Australia), FSCA (South Africa). These bodies enforce capital requirements, segregation of client funds, and dispute resolution.
Unregulated brokers can refuse withdrawals, manipulate prices, and disappear overnight. No regulation = no recourse. Don't trade with them regardless of how good their spreads look.
2. Leverage
EU/UK regulators cap retail CFD leverage at 1:30 for major forex, 1:20 for indices, 1:2 for crypto. Non-EU entities offer up to 1:500 or even 1:2000.
More leverage = more risk. A 1:500 leveraged position moves 5% when the underlying moves 1%. A 2% adverse move wipes out your entire margin. High leverage isn't a feature — it's a loaded gun.
3. Spreads
The marketing trick: "spreads from 0.0 pips." That's the raw spread, available only on ECN accounts that charge a separate commission. The all-in cost = spread + commission. Always compare total cost, not just the spread number.
Fixed spreads are higher but predictable — good for news trading. Variable spreads are lower on average but can spike to 10-20x normal during volatility. Know which type you're getting.
4. Platform Type
MT4/MT5 — Industry standard, massive ecosystem of indicators and EAs. If you want automated trading or custom indicators, you need MT4/MT5. The interface is dated but functional.
Proprietary platforms — Cleaner interfaces, better mobile apps, often simpler for beginners. But you're locked into one broker — your strategies and indicators don't transfer.
cTrader — The middle ground. Modern UI with EA support. Growing but smaller ecosystem than MT4/MT5.
5. Minimum Deposit
Ranges from $1 (Exness) to $500+ (premium brokers). A $1 minimum deposit signals the broker targets high-volume, high-leverage traders in emerging markets. A $500+ minimum signals a focus on serious traders with capital.
Low minimums are good for testing — but don't judge a broker by this alone. A $5 minimum deposit broker can have worse execution quality than a $100 one.
6. Instruments Available
Forex-only brokers give you 30-50 currency pairs. Multi-asset brokers offer forex + indices + commodities + stocks + crypto. If you trade across asset classes, you need a multi-asset broker — running accounts at 3 different brokers fragments your capital and complicates risk management.
7. Swap-Free Accounts
Also called Islamic accounts. No overnight financing charges — required for traders following Sharia principles. But some brokers compensate by widening spreads on swap-free accounts. Check whether "swap-free" actually means "cost-free" or just "no swap, wider spread."
8. Copy Trading
eToro built a business on this. Some brokers integrate with copy trading platforms (ZuluTrade, Myfxbook). Useful if you want to follow verified traders — but verify their track record yourself. Past performance ≠ future results applies to copy trading too.
9. Crypto Trading
CFDs on crypto are restricted in many jurisdictions. In the US, they're mostly banned. In the EU/UK, leverage is capped at 1:2. Some brokers offer crypto CFDs, some don't, and the regulatory landscape shifts. Check your local rules before trading crypto CFDs.
10. Education Resources
Most broker "education" is marketing dressed up as content — basic articles about what forex is, followed by a "open account" CTA. Genuine education means: webinars with real traders, platform tutorials, market analysis that isn't just "BUY EURUSD because our analyst said so."
Few brokers do this well. Don't choose a broker based on education — use independent resources instead.
11. Customer Service
24/5 is standard for forex brokers (markets close on weekends). 24/7 is rare and usually means outsourced weekend staff who can only handle basic queries. What matters: live chat availability, response time on emails, and whether phone support actually connects to someone who can fix problems — not just open a ticket.
Test this before depositing. Send a question. Time the response. If it takes 48 hours for a simple inquiry, you don't want to rely on them during a margin call.
The Bottom Line
TradeTestr lists 20 brokers with all 11 of these filters. No recommendations, no "best broker" rankings — just the data to compare and decide for yourself.
Choose based on your trading style: day traders need tight spreads and fast execution, swing traders need wider instrument access, beginners need regulation and low minimums. There is no single best broker — only the best broker for you.
