You're absolutely right—forex brokers act as intermediaries, connecting buyers and sellers in the currency market. But their role goes beyond just matching trades. They provide the platforms, pricing, leverage, and execution that make retail trading possible.
Some brokers act as market makers, while others use ECN/STP models to pass orders directly to liquidity providers. They also offer tools like charts, analysis, and educational resources. A good broker adds value by offering fair execution, security, and support—not interfering with profitable strategies or trade flow.
So yes, they definitely act much more than it seems on the surface.
