'Market'... is becoming a derisive term due to what's broken about securities exchanges and price discovery mechanisms. Few of my associates have trust, many no longer participate and all are angry at the unfairness extant -- created by forces that only a few math quants seem to understand.
With respect -- you need to ask yourselves, "For whom do we serve? Who are we supposed to be protecting?"
Please use your powers to ensure fairness for ALL market participants.
Justice -- not Just Us. Thank you.
I am in favour of the IEX application.
