What Is a Broker?

Quick answer

A broker is an intermediary that provides traders and investors with access to financial markets. In exchange for this access, brokers charge a fee — typically via spreads, commissions, or both.

Retail traders cannot directly access interbank forex markets or most stock exchanges without going through a licensed intermediary. A broker provides the trading platform, market access, order routing, and often educational resources and analysis.

There are several common broker models. A market maker quotes its own bid/ask prices and takes the other side of client trades, managing its risk internally. An STP (Straight-Through Processing) broker routes orders directly to liquidity providers. An ECN (Electronic Communication Network) broker aggregates quotes from multiple providers, often giving raw interbank spreads plus a commission per lot.

The choice of broker model has implications for pricing transparency and conflict of interest. ECN/STP models are often preferred by active traders for their tighter spreads and because the broker profits from commissions rather than from client losses.

Key factors in evaluating a broker include: regulatory status (is it licensed by a reputable authority?), fund safety (segregated accounts, compensation scheme), trading costs (spreads plus commissions), platform quality, and customer support.
