I have completed chapter 6. Everything was working fine until I got to page 133 where you turn the static nockmarket tab into real-time. The problem is that the code doesn't work. The nockmarket tab is not updating in real-time -- the data remains static.

I have checked out chapter 6 from the code repo and I get the same behavior. i.e. the nockmarket tab does not update in real-time.

Can anybody confirm that after completing chapter 6 that the nockmarket is working in real-time?
