All participants contribute to price discovery. A nanosecond order book helps with price discovery the deeper it is, regardless of whether orders clear.

I think you're trolling with this one. But you had an advantage typing your comment into a web browser compared to all the people who wrote theirs on paper and put it in an envelope with a stamp.

This is a claim, it is not being backed up by evidence.

This analogy doesn't make any sense. Why would a person care about nanosecond price discovery? The only benefit is for whoever controls the computers that are able to do it and profit off of it.

If that's not true then why are these firms paying so much money to have nanosecond advantages?

Why do people doing normal trading want to avoid the exchanges that have HFT computers skimming money off their trades?

There is no mutual benefit here. If there was you would be able to explain it clearly and with evidence instead of just making claims about 'price discovery'.

The price is going to get discovered either way just as it has for hundreds of years, it happening a billion times per second does normal traders no good.
