Market Quality Metrics

Read these first

1. 01Measuring Price Efficiency

   An efficient price reacts to new information once, correctly, and then holds still, measuring how far real prices fall short of that ideal is how researchers put a number on market quality.

2. 02Measuring The Effect Of A Market Structure Change

   When an exchange changes a rule, a new tick size, a new order type, a new fee schedule, proving what the change actually did requires comparing the affected market to one that didn't change, not just watching a before-and-after chart.

3. 03What Makes A Market Good?

   A "good" market isn't just one with a tight spread, it lets traders transact cheaply, in size, without the price bouncing around for no reason, and it stays that way even under stress.
