ECN

Market Structure

What it means

Electronic Communication Network: a system that matches buy and sell orders directly between traders, with no dealer in the middle. It often offers tighter spreads.

Example

On an ECN, your buy order for EUR/USD can be matched directly with another trader's sell order at 1.10500, with the ECN charging a small commission instead of widening the spread.

Mistake beginners make

Beginners assume "ECN = always cheaper." ECNs charge commissions that can outweigh the tighter spread on small trades; do the math on total cost, not just the spread.
