High Frequency Trading Debate: Mano a Mano

Posted by Larry Doyle on July 24, 2009 5:42 PM |

In the spirit of continuing the dialogue on high frequency program trading, please view this ‘mano a mano’ debate on CNBC.

In one corner is Joe Saluzzi of Themis Trading. In the other is Irene Aldrige, Managing Partner of Able Alpha Trading.

Mr. Saluzzi initially exposed this activity to the public in late June. Irene views this trading activity as a natural evolution of modern technology.

Please let me know how you score “the fight.”

    Larry, after listening to that video I think I honestly know less than I did before.

  • Larry Doyle


    Well, hopefully that will change after next Sunday evening as I have Mr. Saluzzi scheduled to join me on NQR’s Sense on Cents with Larry Doyle.

  • Jerry


    Please be fair and schedule Irene (at another time) to give her insight. She knows far more about High Frequency Trading than Saluzzi. Joe is confusing his (perhaps legitimate) complaint about Flash orders and co-location with HFT. They are really separate issues that are being lumped together. In my opinion she won. By the way, I am a retail investor and my discount broker is co-located on the exchange, ask Joe about that.

  • Larry Doyle


    In the spirit of full disclosure, I have already reached out to Irene this week to have her on the show August 9th. Regrettably she has not yet responded. I will persist.

    Believe me, my goal is to fully air and expose all the issues and topics from both sides of the argument so that people are more informed and educated.

  • Jerry


    Cool. That’s all I can ask for.
