We not too long ago mentioned how fragmentation undoubtedly provides to competitors for venues.
In fact, it additionally provides mounted and alternative prices for merchants.
Nonetheless, a few of our current research recommend it could scale back competitors for quotes.

A value setter needs to seize spreads
If we take a look at how inventory markets labored within the Nineties, and the way futures markets nonetheless work immediately, buying and selling was consolidated on one venue. In these single marketplaces, if you wish to seize unfold, you both have to attend till you get to the highest of the queue or make NBBO costs higher.
Buying and selling and routing are additionally a lot less complicated in that context: Everybody is aware of what and the place the most effective costs are — and all merchants have equal entry to commerce at these costs.
One vital participant in that ecosystem is the dealer who units the NBBO costs, the market maker. As a result of market makers need to seize unfold, they sometimes:
