SO what is exactly is a tick when in comes to the stock market data and HFT?
A question from a newsletter subscriber:
Bryan, a very simple question…. what’s a tick?Is it a movement of a tick/pip that has the various associated volume metrics attached or is it a simply price change within the underlying instrument?
I think you answered your own question but I watch my ticks at subsecond.FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
