DTN Satellite Products » Satellite feed to personal app (how?). May 8, 2007 12:26 AM (Total replies: 24)

I've asked this question several times over the phone but could never get a solid answer. Basically I want to be able to stream all 3000+ symbols off nasdaq in real-time tick by tick. Is this possible using the satellite feed? Please outline any drawbacks or issues. I've seen some people saying they are streaming 50,000+ symbols at once from various exchanges but does this include every single tick for each of the symbols? Also how does the historical data stream work? Does it broadcast the data once per night/week/month? And does the historical feed include tick data for all exchanges and symbols and include trades. bids, asks and volume?

Why on earth do you charge $400 for the sdk? If it were free I would certainly subscribe to the satellite service but $400 is a bit of an insane price to pay for data you have already paid to have access to.

Ok but if you're saying that Ensign or InvestorRT can process this data and possibly export it then there must be a way to feed the data from the receiver into my app. I am a low level/reverse engineer by profession so have no problem in making an effort at trying to figure out how to decode the data. How does the data from the receiver get to those apps (Ensign and InvestorRT)? I heard that you need some kind of serial interface so is there some kind of serial software plugin for those apps? Is the protocol anything like the data that is streamed into dastrader pro (dastrader.com) which also uses bit swapping and cross referencing when they formulate packets?

Is it possible to get some sample data from the satellite feed coming from the receiver so that I can take a look at it and with some info on what symbol data it contains? I really want this service but if it's not going to work for me I'd rather not waste my time with it.

Thanks for the lightning response! What I meant by "all of the data from the exchange" is simply the trades, bids, asks, volume etc. for each symbol on nasdaq for example. Does the satellite feed deliver this? So the data is binary? Is it decrypted before being passed from the receiver to the pc. I don't mind spending time figuring out the protocol that encapsulates the data but if it's encrypted then thats another thing.

What I want to do is collect streamed data from the satellite feed for use in my personal app later on. What hardware (cables, adaptors etc.) do I need to accomplish this? Once the data has come through the receiver box is it still encrypted or is it in a form where it can be decoded or seen in plain text? Does ALL of the data for all exchanges come through the receiver box or is there some kind of filtering system? I am seriously considering subscribing to the satellite feed but need to have these questions answered before doing so. Thanks.
