ECN

An ECN connects traders directly to a pool of liquidity providers - typically a mix of tier-1 banks, prime brokers, hedge funds, and sometimes other retail participants. When a trader places an order, the ECN's matching engine finds the best available counterparty price from that pool and fills the order electronically, typically in milliseconds. The broker takes no position and earns revenue through a transparent per-lot commission rather than an inflated spread.

The structural advantage of ECN over dealing-desk execution is the elimination of the broker's conflict of interest. Because the broker makes money on volume rather than on the spread, it has no incentive to slow execution, requote, or widen prices against the client. True ECN brokers also display a live order book (depth of market), allowing traders to see pending orders at different price levels - information that is unavailable with market-maker quoting.

The practical trade-offs are worth understanding. ECN accounts typically carry minimum deposits of USD 200–1,000 or more, and the raw spreads (sometimes as low as 0.0 pips on EUR/USD) are accompanied by commissions in the range of USD 3–7 per side per standard lot. Active traders and scalpers almost always find ECN total costs lower than commission-free market-maker pricing once volume is factored in, but low-frequency traders making only a few trades per week may find the simplicity of a spread-only account adequate.
