Broker Models: A-Book, B-Book & Hybrid

A-book (STP/ECN): Orders route to external liquidity providers (LPs). The broker earns via commission/spread markups. Execution quality depends on LP depth and routing.

B-book (Market Maker): The broker internalizes client flow. Pricing mirrors the interbank market but fills are internal. Risk is hedged dynamically. This can enable tight spreads and fast fills.

Hybrid: Many brokers segment flow—profitable or high-volume clients route A-book, small or inconsistent accounts may be internalized.

Pricing: Spreads, Commissions & Swaps

• Spread: Bid–ask difference. Can be fixed or variable.
• Commission: Per-lot fee common on ECN accounts with raw spreads.
• Swap: Overnight financing charge/credit for holding positions past rollover.

Compare costs when evaluating a regulated forex broker. Spreads tighten during liquid sessions (London–NY overlap).

Execution & Liquidity Providers

Orders aggregate through a liquidity pool (banks, non-banks, ECNs). Smart order routing seeks the best quote, but slippage can occur in fast markets. Use realistic expectations when following forex signals.

Regulation & Safety of Funds

Choose brokers with strict oversight, client fund segregation, reporting, and complaint handling. Regulation reduces counterparty risk but does not eliminate market risk.

Account Types & Platforms

• Standard vs ECN/Raw: Wider spread/no commission vs tight spread/commission.
• MT4/MT5: The most common platforms for manual and signals-based trading.
• Swap-free options: Available with specific terms; check product disclosure.
