Here’s the difference: In TradFi, orders routed to lit exchanges can’t be front run. Period. If you trade futures on CME or ICE, nobody is able to step in front of your order and extract value from it. Of course, if you use a broker to trade stocks that sells your order flow, then the process becomes more opaque. But the rule is that orders must be executed within the NBBO if they are internalized and otherwise routed to the venue with the best price. This isn’t at all similar to MEV, which in many cases explicitly enables front running.
