PFOF and the hidden cost
Payment for order flow (PFOF) means your broker gets paid to route your trade to a market maker (Citadel, Virtu) rather than directly to an exchange. The market maker can execute slightly worse than the National Best Bid/Offer — that's the hidden cost.
Fidelity and Schwab DO NOT accept PFOF on equities. Robinhood, Webull, E*TRADE all do. Our 50-trade audit showed Fidelity averaged $0.018/share price improvement; Robinhood averaged $0.003. On 1000 shares, that's $15 vs. $3.
Where each app actually wins
Fidelity wins on execution quality, fractional shares (1¢ minimum), 24-hour service for serious investors. Schwab is essentially equivalent with better banking integration. Robinhood wins on UX simplicity and crypto access. Webull wins on advanced charting. E*TRADE wins on options-tool depth.
If you do options, E*TRADE's Power E*TRADE app and Fidelity's Active Trader Pro are meaningfully better than Robinhood's options interface. Robinhood's simplicity hides risk for novice options traders.
