Hi Patrick- I see you left TT and now work for Nodal Exchange. I had to look that one up. I was not familiar with it. You put this post in Trading Software. Are you only asking about Futures and automated traders? Most of our equity platforms use servers on AWS with a cross connect to the NJ matching engines. They are very fast but not hosted, institutional fast like being in a cage at NY4. On the Futures side, we use desktop software like CQG, TT, CTS T4, Rithmic and EZE EMS. These are also desktop platform, and you likely know their Roundtrip times and latencies better than most. You also know it is also a function of the customers location and path on the internet. So my questions to you are, are you only asking for automated hosted futures traders? What is the end game? The Nodal Exchange looks like it offers only institutional products and not for retail.
