Hot Topics in Tech: Smart Routers

• Today's topic was inspired by the following listener question: Question from See16: Can you please do a deep dive into smart routers on a future program? They are the secret sauce of the market these days but no one really seems to understand how they work. Shedding some light on the otherwise dark world of routing would be a great service. Smart Routing Deep Dive: Quite a few things happen after you hit the trade button in the options market - probably much more than most people realize. Your order has to get routed from your broker/execution platform to the exchange. But it's not a simple path. That's where smart routers come in. What is a smart router? What do they do? What makes them smart? What are the different rules/filters/configurations that most smart routers have to consider? - NBBO, exchange fees, size, exchange pricing model, PIP auctions, payment for order flow rates, etc. What about resting orders? Are the smart routers constantly monitoring them and rerouting if necessary? Why do we need them in the options market? How do options smart routers differ from equity smart routers? Why have smart routers become so controversial in the options market? Spreads: This is the Achilles heel for many "smart" routers since every exchange has its own spread book and they don't talk to each other. So you could easily work a spread order that lines up on one exchange but, because your order was routed to a different spread book, your trade isn't filled. How do we overcome the spread routing issue in 2018? Is it a tech problem or a regulatory problem? Final thoughts/takeaways on smart routers?

The Inbox: Listener questions and comments

• Question from Nikes T: Hey Options Insider! Love the network particularly the tech talk. We need more episodes! On an upcoming show do you think you guys could talk about why dark pools don't exist in the options market? Is it a tech limitation or something else?
• Question from LaLaLad: Does block chain have any practical use on the trading front or is it all just back office stuff?

  In response to tweet: Are exchanges shooting themselves in the foot by continually hiking market data fees?
