  1. Hi Khader,

    I am trying to learn more about FIX scenarios and I liked your FIX presentation that you have posted online. But I need few more scenarios as examples. Can you please let me know where I can find them? I did not find them on the FPL website.


  2. Ashish,

    Download FIX Protocol 4.3 specifications. There are 7 volumes in it. Volume 7 has FIX usage for all supported products. It may be bit complex initially but once you start following it, you may find it easy. There are few things before you start –
    – Your organization role; either you are Buy side, sell side or exchange
    – Products that you are dealing with
    – Trading process of those products

    If you need any further info let me know.


  3. Hi Khader,

    Your materials on YouTube is just great.

    I am planning to develop a new FIX engine, for which I would like to ask you where can I find inputs/discussions, regarding

    – Whats lacking in current FIX engines in market?
    – The latency, stress tolerance & reliability figures for existing FIX engines in market.
