ECN (A-book) — pass do banks
Cost comparison

- MM: 1.0 pip spread = €10 (no commission)
- ECN: 0.1 pip spread + €7 commission = €1 + €7 = €8

Najczęstsze pytania
MM/B-book — szczegóły?
Market Maker (B-book) = broker = counterparty trader. Mechanika: gdy trader buy EUR/USD, broker SELLS przeciwna strona. Broker holds position internally, NIE passing do banks. Profit broker: gdy trader traci, broker zyskuje. 80% retail loses → broker stable revenue. Spread: low (0.5-1.5 pips EUR/USD typical). Broker absorbs cost bo profit jest z client losses, NIE spread. Commission: zazwyczaj BRAK. "Free trading" marketing. Conflict of interest: broker incentive trader to lose. Stop-loss hunting possible — slight price spike to trigger SL. Reqkotes during news (refusing fill). Slippage favorable broker. Defense argument MM: "We hedge net exposure with banks." Reality: small brokers don't hedge, profit z client losses direct. Larger brokers hedge partially. Examples MM: most CFD brokers (eToro, Plus500, AvaTrade), big retail (XM standard, FxPro standard accounts). Regulation: B-book legal, ale FCA UK 2018 banned "binary options" related (similar model). MM legal everywhere ESMA. Verification: broker statement "STP/ECN execution" vs "Dealing Desk" = transparency required FCA.
ECN/A-book — szczegóły?
ECN (Electronic Communications Network) / A-book = trades passed do liquidity providers (banks). Mechanika: trader buys EUR/USD, broker matches z liquidity provider (Goldman Sachs, JP Morgan, etc.). Broker NIE counterparty, tylko intermediary. Profit broker: commission per trade. NIE conflict z client. Spread: raw (0.0-0.3 pips EUR/USD peak hours). Tight bo bank-direct. Off-peak wider. Commission: €5-10 per lot round-trip (e.g. IC Markets €7, Pepperstone €7). Total cost = spread + commission. Usually similar do MM total cost. NO conflict of interest: broker wants traders profitable (more trades = more commission). Best execution incentive. Examples ECN/STP: IC Markets, Pepperstone, FP Markets, Tickmill, XM ECN (premium). Verification: (1) Spread tight pre-NY open (0.0-0.2 pips EUR/USD). (2) Commission visible w trade history. (3) Real liquidity providers listed (FCA UK requires disclosure). (4) Volume info CME forex futures matches broker volume (correlation high). Caveats: smaller accounts (€500-5k) often B-book in "ECN" brokers (mix model). True A-book usually €10k+ accounts.
Hybrid model — większość brokerów?
Reality: most brokers HYBRID, NIE pure MM lub ECN. Mechanika hybrid: (1) Small accounts (€500-5k retail): B-book wewnątrz. Broker risk manages own book. Small traders most lose anyway. (2) Larger accounts (€10k-50k): A-book passed to banks. (3) Profitable traders: A-book — broker doesn't want exposure. (4) Losing traders: B-book — kept internal. Why hybrid: optimal broker profit. Profitable traders A-book (NO loss to broker), losing traders B-book (broker captures losses). Detection hybrid: (1) Spread changes between account types. (2) Different execution speed for different traders. (3) "Premium" accounts (€10k+) often A-book. (4) Broker disclosure (FCA UK regulated brokers must disclose). Pure A-book brokers (rare): claim ALL trades A-book regardless account. IC Markets True ECN, FP Markets Raw Account, Pepperstone Razor. Pure B-book brokers: CFD-only platforms (eToro, Plus500). Marketed as "0 commission" but spread wider. Recommendation: large account = explicitly ask broker about execution. €10k+ traders deserve A-book.
