Dear Sirs and Madames,
I would like to see IEX established as a public exchange because I think I will have access to a better fair and willing pool of partners with which to trade securities. I believe that High Frequency Trading is stripping the current exchanges of legitimacy, it is becoming nothing more than a race, a test of speed. I think currently some participants have unfair speed advantages. I am not a professional trader but I spend a lot of time looking at market patterns and to me liquidity appears and disappears too erratically. I think it is time to level the field and offer interested investors the choice to route their orders to this exchange as they currently can with many others.
Thank you,
Susan Janson,
Investor
