A-Book vs. B-Book Prop Firms: Decoding the Models for Trader Success
The core difference between A-Book and B-Book prop firms lies in their execution model and fundamental conflict of interest. A-Book firms route trader orders directly to real markets (liquidity providers), earning revenue from commissions and fees, thus aligning their success with the trader's profitability. Conversely, B-Book firms act as the counterparty to their traders' positions, meaning they profit directly from trader losses, creating an inherent conflict.
