Regulatory Verification
Start by verifying the broker's license directly on the regulator's website. Every licensed broker has a registration number searchable on FCA, CySEC, ASIC, or other regulatory databases. Check the license scope to ensure it covers the services offered. Be wary of brokers claiming regulation but not appearing in official registries or listing expired licenses.

Financial Health Indicators
Regulated brokers publish annual financial statements. Review net capital adequacy, client funds segregation practices, and profitability trends. A broker consistently operating at a loss or with declining capital reserves poses elevated counterparty risk. Check if the broker participates in investor compensation schemes that protect client funds in case of insolvency.
Practical Testing
Before committing significant funds, perform practical tests: open a small account, execute trades during volatile markets to check execution quality, and process a withdrawal to verify speed and smoothness. Monitor slippage rates, requote frequency, and whether the broker honors advertised spreads during news events. These real-world tests reveal more than any marketing material.
