I have been testing if there is a difference but I can't really tell if there is any.

if anyone reading this has a high-quality fast internet connection yet is still experiencing hiccups with denali data, try turning off compression while keeping everything the same and see if things improve. i know this is counter to sierrachart's advice but if the reason for the data hiccup is NOT due to your internet connection because you have sufficiently fast internet, turning off compression may help. it has for me but i do not know why.

I never experienced these issues with CQG and the exact same setup, even during 2020 shenanigans and halts.

this is how i figured out the aforementioned trick b/c i also never experienced these issues with CQG and CQG was faster. weird, right? not only do i have fast internet, i also do not need market depth or tick data at all so i only subscribe to top-of-the-book market data and set intraday data storage to 1 minute. that means bandwidth itself was never the issue, either with CQG nor Denali.

even when denali was working perfectly, 50ms chart update interval with Denali feels slightly slower than 50ms chart update interval with CQG feed. if i want the same speed and feel as i get with CQG feed set at 50ms chart update interval, i noticed i have to set Denali feed to 20-30ms chart update interval. and since in my case, bandwidth is trivial, the only difference i could think of between my current denali feed and cqg was that denali feed was compressed and cqg was uncompressed.

i still think compression matters if the reason for your slow denali feed is due to internet speed/bandwidth issues but if that's not the case, try turning it off to see if you can get somewhat of a closer experience to CQG's fast feed.

and before sierrachart counters this post by stating how the compression times are infinitesimally small so as to be barely noticeable to the human eye, yes i am well aware of the compression times. i am simply presenting my anecdotal experience in case it helps someone who's going through the same frustration i did. i do not know why this does or does not work but there is no harm in trying.
