ECN vs STP Broker Execution: Raw Spreads, Commission & Depth of Market
True ECN brokers connect traders directly to an interbank order book with visible Level 2 Depth of Market (DOM), passing raw interbank spreads (from 0.0 pips on EUR/USD) while charging a transparent fixed commission (e.g., $3.50 per lot). STP brokers route orders to liquidity providers without DOM, embedding their profit into an invisible spread markup (1.2+ pips).
Broker execution model directly influences trading profitability. For high-volume scalpers and intraday algorithmic systems, spread markups on STP brokers create thousands of dollars in drag compared to raw-spread ECN environments.

The Hidden Cost of "Commission-Free" STP Trading
A broker advertising "Zero Commission" charges a 1.5-pip spread ($15 per standard lot). An ECN charging 0.1 pip spread ($1) plus $7 commission costs only $8 per round trip, saving active traders $700 per 100 lots executed.
