Datafeed

Not sure I understand your question "on every pulse". Satellite is a completely different method of delivery compared to Internet. It is a true Broadcast, meaning the client cannot "request" anything from the satellite. We send every tick, and if you aren't ready to catch it, you will miss it. There is no backfill (but most software will capture and store off the data for you). So, during a weather outage (has to be a very big storm to block the signal), you will miss data and you have no way to tell the satellite "hey... resend that for me".
Our DTN Real Time service which is $129/mo, is the exact same feed we provide to our Redistribution customers (Brokers, Websites, other streaming data providers). So, it would be akin to the customer having a Reuters datafeed going direct to your computer.
Hope this answered your question.
DTN.IQ is our retail product which includes the software. IQFeed is a datafeed service only (no client interface included) compatible with 3rd party software.
Neither has automatic bad tick filtering. In DTN.IQ you can right click a bad tick to remove it. IQFeed is a feed only, so it would be up to the 3rd party client software to provide a filtering mechanism.
I have a friend that uses your service from a rural location: from their ranch. The service is quite nice and they are happy. During a really big weather outbreak they dont rely on the feed: but the feed at their location performs well even during poor conditions.
It works well enough that I am considering putting it out at one of our properties as a second backup location.
In theory. You can watch 1300 symbols, depending upon how active they are. DDE is an old technology that relies on messages being sent. DDE is limited in the number of messages, so if you have to many symbols with too many fields displayed, the messages can overwhelm your system. I have run a few hundred symbols without problem on DDE, but going much higher may cause slowdowns.
As for the 1300 symbols, depending upon how active they are, you can flood your internet connection as well (even broadband). 100 of the most active symbols will use 25-50Kb/s. The main reason we allow so many symbols is for customers who want to watch an entire future or option chain. A chain on QQQ for example could watch nearly 700 symbols for example.

What is % difference between number of ticks that DTN satellite and eSignal in average provide for the session?
For example: ES Z03 Sep 19th â eSignal 45,097 ticks and DTN satellite â more than 50,000 /did not catch a full session/
