The Annual Math
A trader executing 10 trades daily at $1 hidden PFOF cost each pays $2,500 annually to Citadel. A highly active trader could pay $10,000+ per year in hidden execution costs.
Active traders are most harmed by PFOF in absolute dollar terms — more trades means more spread capture by Citadel Securities.
