This looks like a purposeful distraction from Citadel’s cash cow of “payment for order flow”, which essentially allows them to cache orders at prices delivered to consumers less profitable than what they realize when matching at slightly different times, advantageous to Citadel, from their cache. Consumers using Robinhood famously are handing profit to Citadel, and the Robinhood founders[edit]/shareholders. They kick back a fraction of their profit to ensure apathetically timed orders keep being funneled through Citadel.
