Which is better?
Payment for order flow (PFOF) offers brokers revenue by routing orders to market makers, often resulting in tighter spreads for retail investors but raising concerns about conflict of interest. Liquidity rebates incentivize traders to provide market depth, improving price discovery and reducing overall trading costs while promoting more transparent market dynamics. Evaluating efficiency depends on market structure priorities: PFOF benefits retail access and broker compensation, whereas liquidity rebates enhance market quality and fairness.
Connection
Payment for order flow incentivizes brokers to route orders to specific market makers, enhancing their order flow volume and enabling them to offer liquidity rebates. These liquidity rebates improve market liquidity by rewarding market participants for adding depth to order books, creating a symbiotic relationship that lowers trading costs and optimizes market efficiency. Consequently, the combined effect of payment for order flow and liquidity rebates fosters a more competitive trading environment with tighter bid-ask spreads.
