Explain the Difference between PFOF in Options versus Stock Trading.

PFOF is generally more prevalent and lucrative in options trading than in stock trading because options often have wider bid-ask spreads, providing a larger margin for market makers (wholesalers) to offer price improvement and still pay the broker a rebate. Stock trading spreads are often very tight (penny or sub-penny), leaving less room for the wholesaler's profit and the PFOF payment.

The complexity and higher risk of options also contribute to the wider spreads.
