ECN (Electronic Communication Network)

An ECN (Electronic Communication Network) is an electronic system that automatically matches buy and sell orders from multiple market participants, including banks, hedge funds, other brokers, and sometimes retail traders. ECN brokers provide direct market access with variable spreads that can be extremely tight during liquid times. They typically charge commissions rather than widening spreads for revenue and do not take the opposite side of client trades.

The key advantage of ECN brokers is transparency. Orders are visible in the aggregated order book, spreads reflect real market conditions, and the broker has no incentive to see clients lose because their revenue comes from commissions per lot traded regardless of outcome. During high-liquidity periods like the London/NY overlap, ECN spreads on EUR/USD can drop to 0.1 pip or even zero, with commissions of $3 to $7 per side per standard lot. The downside is that during news events or thin liquidity, spreads can widen dramatically, and unlike market makers, ECNs will not hold a fixed spread.

For example, an ECN broker might quote EUR/USD at 1.08499 bid and 1.08501 ask during active hours, a 0.2 pip spread, with a $3.50 commission per side per standard lot. Total round-turn cost is about $5, making it very cheap for high-frequency strategies. During NFP, the spread might spike to 5 pips for a few seconds. A trader who clicks market buy during that window pays much more, which is why many ECN users avoid trading around major news.
