Notes on Switching from Steidlmayer Updating to Aspen/DTN

Aspen has put a fix on their website to facilitate composite contracts (merged pit session with a night or electronic contract). Go to the Aspen site to download the fix.

As of 8/20/2002 the Steidlmayer Servers no longer distribute data for Capital Flow 32 or Capital Flow 3.7. THe servers can be still used for the time being to fill in history up until that date. 

This page will continue to be updated  with information about the changeover process.

Some Answers to Obvious Questions:

Q: Aspen/DTN seems to be able to bring up a lot of data in a chart but Capital Flow doesn't seem to pull it in. Why is this?
A: We are working on this, it is a Capital Flow restriction and not related to Aspen. At some point in the next month or so (July, 2002) we should have a version on the server that will pull in up to 2 years of history from Aspen.

 

Q: Why don't some contracts like Crude Oil and Australian Dollar update from Aspen?
A: This could be due to the Alternate Symbol having been entered in lower case letters. DTN assumes that this indicates an exchange code and attempts to interpret the rest of the symbol after the initial lower case letter as the symbol on that exchange. Unless you are interested in Sydney, Canadian, or other exchanges, it is probably better to enter Alternate Symbols in upper case.

 

Q: Why don't I get the last two periods when updating from Aspen?
A: The Aspen/DTN servers are on Eastern time, Steidlmayer servers are on Central time, so there is an hour time difference between the two. For this reason, it is probably not good to mix updating from Aspen and Steidlmayer on the same day. 

 

Q: I signed up for delayed quotes on some exchanges, and these contracts do not update. What's up?
A: Aspen/DTN uses a symbol prefixed with "d_" for delayed data. This is the symbol that must be used by Capital Flow. See the page on Aspen/DTN Symbols for more information.

 

Q: Why don't E-mini and euro contracts from the CME don't update from Aspen?
A: The symbols for these contracts are different in Aspen. See the Aspen/DTN Symbols page for more information.
A: Users who update using CQG will still be able to use this option. You may have to get an enablement from our server for CQG to appear as a feed option. Contact our office if you have any problems.

 

Q: Who do I contact about getting Aspen/DTN as a feed option?
A:  Jim Miclot at 312-360-0619

 

Q: Are there differences in symbols between Steidlmayer and Aspen?
A: Most stocks will use the same symbol. There are a number of futures contracts that require a different symbol be used to request data from Aspen. See the page on Aspen/DTN Symbols, or go to the Aspen Symbol Lookup function directly on the aspen site.
