This is an ongoing myth that needs clarification. Direct NQDS and SIAC feeds are typically no more than 30 milliseconds faster that a T1 Hyperfeed connection. That is a completely imperceptible difference. In fact, I've compared Watcher (which uses NQDS data and is considered by many to be the leanest and fastest order-entry platform in existence) tick by tick over the course of a week with an order-entry system using Hyperfeed (which will remain nameless). There was no visible difference in quote speed. Zero. None. I did the same comparison using REDI+. Our Hyperfeed driven software was actually visibly faster at times than REDI+. Hyperfeed does a lot of data scrubbing and calculating on its servers so end users don't need to do it on theirs. In the end, the latency difference is largely a wash.
The 30 ms delay may be true if you are in the East Coast, but the latency increases as you move further to the West Side. If you trade in San Diego for example, there will be multiple relay points if you subscribe your feed from vendors, and that increases the delay beyond just 30 ms...by getting NQDS/NTDS, they can provide that feed quicker and you can see the differences, especially on high volumes (I placed Realtick side by side with another software that takes NQDS, and I noticed a half second of a difference). Besides, speed is not the only thing in concern, reliability is better with direct feed because you don't have a middle man (vendor) that introduce another point of failure. The reason we trade with direct-access technology instead of online broker is to avoid the middle man, so why would we do differently when it comes to the feed?
