It will not be implemented, of course. But it's a bit interesting to bring up MEV and the NBBO rule together. The situation in the US is that retail order flow is goes to wholesalers, and wholesalers subscribe to the SIP feed (which is substantially delayed) and the direct feeds from venues, and they can decide whether they want to offer price improvement compared to the *delayed SIP feed* based on the more recent data from the direct feeds. It doesn't seem like retail is getting a great deal in that situation.
