I'm sorry I'm late getting back to this thread! Hopefully I can clarify a few things.
First, I'm not sure where I talked about 'HFT' in the context of this post on our new FIX service. I wasn't arguing that our FIX adapter on the new platform competes with HFT algos directly. I was only pointing out that as far as FIX services go, I believe it is one of the, if not 'the', fastest one of those. If you can point out which statement I made that claimed this FIX solution competes with HFT, please let me know so I can clarify.
Second, our automated trading solutions on our new platform are more competitive than ever before. For example, our Autospreader has been clocked in production re-quoting (wire to wire time inside our network) well below 30 mics and auto-hedging well below 50 mics. So, to say we are not in the space is simply incorrect. We also know that we are competitive because of the many users we have around the world using our automated trading tools. We have more engineers than you may realize, and certainly more than we did in the past, who have come out of HFT prop firms and so many of the strategies used (including pre-creating orders as you mentioned) are known to us and will certainly make their way into the product in the coming months.
It's important to note that all our recent talk about performance is not referring to X_TRADER but to our new platform which has slowly been gaining traction over the last 18 months. It grew significantly in terms of volume and number of users in the second half of 2016, largely on the back of the performance improvements we've made in TT over X_TRADER.
