ECN brokers are financial intermediaries that connect traders directly to the market, allowing them to buy and sell assets like currencies and stocks without the interference of a traditional market maker. This means that trades are executed at the best available prices from multiple liquidity providers, leading to tighter spreads and more transparent pricing. Unlike traditional brokers, ECN brokers charge a commission on trades instead of marking up the spread. This model benefits traders by providing access to real-time market data and faster execution speeds, making it an attractive option for those looking to engage in forex trading or other financial markets.
